A thing from my setting that intervenes when someone tries to change history by traveling through time without permission.
Time Killer CR 35
A mighty automaton stands before your eyes. Made of silvery metal and shaped like an elf, it appears to be gazing somewhere in the air, as if seeing things you don't notice. Suddenly there is a glow and it disappears.

Alternate Self (Su)
Even if a creature find a way to overcome the Eternal ability, a time killer has a backup plan. When a time killer is permanently destroyed, it has a chance of being replaced by an exact duplicate of itself from an alternate timeline. If the time killer decides to invoke this power, the chance it works is 50%, plus a percentage equal to the time killer’s Charisma score (92% for a typical time killer; maximum 99%). If the power is successful the original time killer ceases to exist (and cannot be raised or restored by any power short of direct deific intervention of an Elder One with Double Time Portfolio). Instead, a new version of the time killer comes into existence from an alternate timeline. This time killer has the same memories and history as the original time killer, and is game-mechanically identical. If the body of the original time killer still exists and is in a location and situation that the new time killer would find acceptable, the new time killer appears in that place (wearing whatever the original time killer’s body was wearing). If not, the new time killer appears as close to the original time killer’s body with no equipment.
Alter Probabilities (Su)
The time killer may spend an aevum to bend future timelines towards a preferred set of results. The time killer may skew by 25% the chance of something happening that is determined by a percentile die roll. The percentile roll can represent something the time killer is aware of (like the chance of a creature being missed due to blink or displacement to 25% or 75%), or something more smoky, like an encounter on the table of the random encounters during a travel. If the percentile roll applies to an ongoing condition or effect, the skewed percentile lasts for 1 round per time killer HD. This ability cannot reduce the chance of something happening below 0%, nor increase it above 100%.
Back to the Future (Su)
The time killer can spend two motes to fling itself briefly into the future to observe the results of proposed acts or decisions in its present. The base chance for receiving meaningful information is 99%. This roll is made secretly by the GM. If the ability succeeds, the time killer gets one of the following four results:
Weal (if the action will probably bring good results).
Woe (for bad results)
Weal and woe (for both).
Nothing (for actions that don’t have especially good or bad results).
If the ability fails, the time killer gets the “nothing” result. There is no way to tell if a “nothing” result is the consequence of an action with no particular results or a failed use of this ability. This ability can see into the future only about 1 hour per HD of the time killer, so anything that might happen after that does not affect the result. Thus, the result might not take into account the long term consequences of a contemplated action. All efforts to use this ability by the same time killer about the same topic use the same die result as the first use of the ability.
Cancellation (Su)
A creature or object reduced to 0 or less hp by a time killer is disintegrated by the flow of time.
Chronal Cannon (Su)
The time killer can shoot a cannon of time energy from its chest as a standard action. The time killer can choose to fire the cannon as a 240-foot line or a 120-foot cone. A successful DC 45 Reflex save halves the damage from this attack. The save DC is Charisma-based.
Do Over (Su)
As a swift action the time killer may spend 1 aevum to mark a moment as a restore point. All changes made during the next turn (damage dealt, resources spent, movement taken) should be noted by the GM. At the beginning of the time killer’s next turn, before taking any other actions, as a full-round action the time killer may spend two additional aevum to jump back in time to his restore point. This undoes everything that has happened in the past turn, since it marked a restore point. Creatures within 60 feet of the time killer remember the events of the now-erased round of action, while creatures further away are oblivious to the brief time jaunt.
Eternal (Ex)
The time killer always was and forever will be. So long as time continues to flow, the construct cannot truly be destroyed. If it is destroyed, another instance of the construct from elsewhere in time replaces itself. The construct can replace itself instantly, but it usually chooses to wait at least 1 week to study its attackers before it chooses to reappear. Because this ability require the time to flow, it’s deactivate in a time stop spell, a plane with the timeless trait or any other environment in which the time is stagnant.
Flaw of Time (Ex)
A time killer, despite slipstream and the time subtype, is not immune to the slow spell and suffer a -6 penalty to save against it.
Foresee Battle (Su)
As a free action when rolling initiative, the time killer can spends 2 motes of time to roll twice on the initiative check and take the higher result.
Greater Starflight (Su)
A time killer can survive in the void of outer space, and flies through outer space at incredible speeds. Although the exact travel time will vary from one trip to the next, a trip within a solar system normally takes a time killer 2d6 hours, and a trip beyond normally takes 2d6 days (or more, at the GM’s discretion).
Immunity to Magic (Ex)
A time killer is immune to any spell or spell-like ability that allows spell resistance, except as noted below.
• A slow spell negate the displacement, freedom of movement, and haste spell-like abilities, the improved evasion defensive ability and the time dilation special quality for its duration.
Insight (Su)
While its foresight ability is active, the time killer gains its Wisdom as an insight bonus to all saving throw (already calculated in the statistics).
Legendary Reflexes (Su)
A time killer can, 1/day, act first in initiative. The decision must be made before initiative is rolled. Two beings with the ability to act first would roll for initiative normally against each other.
Magnetar (Ex)
Once a time killer has identified a target for elimination, the two beings are inextricably linked, and the time killer can follow the target anywhere and in any time. Treat this as an infinite-range Spell Stowaway attuned to any magical methods of movement.
Mythic (Ex)
A time killer has Mythic Power (10/day, surge +1d12) and counts as a 10th-rank Mythic creature. A time killer can use any of its spell-like abilities as the Mythic versions of those spells (if a Mythic version of that spell exists), expending Mythic Power as normal. It can also expend Mythic Power to use the augmented versions of these spells.
Motes of Time (Su)
Every time killer has a pool of temporal energy generated by its interaction with the dimension of Time. A time killer can draw a number of motes from its temporal pool each day equal to 3 + its Charisma modifier. Regardless of the action taken or the number of motes spent, a time killer can only spend motes of time three times per round.
By spending 1 mote of time as a free action, the time killer can use one of the following mote powers.
Spare Second: Take a swift action that does not count against the time killer‘s normal limit of one swift action per round.
Take Two: Act in the surprise round when the time killer would not normally be able to do so.
Fast Suffering: Reduce the duration of any negative condition or effect from which it is suffering by 2d6 rounds.
Personal Action: Take a move action as a swift action.
Sudden Action: Grant an ally within 60 feet that it can see an additional move action on that ally’s next turn. In addition, the time killer can spend 1 mote of time as a swift or immediate action to grand itself or an ally within 60 ft. a +3d4 mote bonus to certain checks (see below). The time killer can decide to add this bonus immediately after seeing the result of the original die roll but before the result is revealed.
Defensive Retry: One saving throw.
Detailed Retry: One skill check or ability check.
Offensive Retry: One attack roll.
Time of Battle: One damage roll, or armor class (as a dodge bonus) until the beginning of its next turn.
Personal Time (Su)
The time killer can take risky actions and, if things go badly, simply reverse its personal timeline to before it made the effort. At the beginning of its turn, the time killer spends an aevum as a free action. It then takes one normal round of actions, with all results noted temporarily. After its round of activity, before the next creature’s turn begins, the time killer must decide if it is going to keep the round of activity or just took, or rewind itself.
If it keeps the round of activity, any changes made to any character during its turn become permanent. If it decides to reverse it timeline, it goes back to the moment it spent the aevum, and all changes that occurred during its round are erased from all creatures and items. The time killer is left with a standard action, but is considered to have spent an aevum and made use already of its 2 move action and one standard action. No one but the time killer remembers actions that took place during a round of time it reverses, and only divination spells of 9th level or higher can reveal such events. If a time killer is killed or knocked unconscious during a round of personal time, it automatically reverses back to the beginning of its turn.
Sense the Fracture (Su)
A time killer automatically know if in the dimension where it is currently, a creature travel in time. The time killer automatically know the name and position of the creature and can teleport in his position (in any time) as a swift action using greater teleport, interplanetary teleport, or plane shift, automatically marking him for magnetar.
Slipstream (Su)
A time killer is unaffected by temporal effects (such as temporal stasis), cannot be undermined by time travel (someone cannot go back to its past and simply kill him for instance). If a time killer is within the area of a time stop spell then it gains access to the additional rounds.
Swap (Su)
The time killer may spend 1 aevum as a swift action to stop time and trade places with a creature within 60 feet before restoring the flow of time. The creature must be one the time killer could reach with the movement available to him at the time the power is used. The creature must also be one the time killer could lift and carry (neither too heavy for the time killer to move at all, nor grappled, entangled, or otherwise anchored in place). If the time killer readies to use this power in response to an attack, he may make the Swap after the attack is announced, but before the roll is made. The attack cannot be aborted (because the time killer waits until it is already begun), and the attack roll is made against the new target. A time killer may spend 2 aevum to use this ability as an immediate action (which normally functions as if the time killer has readied to use the power).
Temporal Displacement (Su)
As a melee touch attack, a time killer can send a creature some rounds into the future. A DC 45 Will save negate the effect. On a failed save, the creature disappears in a flash of temporal energy only to reappear in the same space 3d4 rounds later. This effectively removes that creature from combat for the duration. If the space is occupied when the creature returns, it suffers no damage and is shunted aside. The save is Charisma-based.
Temporal Doppelganger (Su)
The time killer can spends 1 aevum to call a duplicate of himself from some time in the near past or future, from a time when the time killer wouldn’t have been doing anything important. The duplicate is controlled by the time killer as his own body, and the time killer can hear and act in both bodies (which use a single initiative check in combat). The duplicate lasts for 1 hour, and must remain on the same plane as the original time killer, or it dissipates (as if the duration of the ability had ended). The time killer may extend the duration for a second hour by spending two more aevum, extend it to a third hour by spending three more aevum, and so on. Although the time killer is literally in two places at once, his split mental attention means he can’t operate both timeline’s bodies at full efficiency. All actions taken by either body counts against the time killer’s total action for a round. For example the time killer could have one body take a move action and the other take a move action and a swift action, or he could have one body take a full-round action and the other just a 5-foot step (but remember time dilation). Similarly, any attacks of opportunity made by either body count against the time killer’s maximum number of attacks of opportunity per round. However, the time killer may take as many free actions as each body is capable of, rather than be limited to the number of free actions the GM considers reasonable for a single body to take. Also, since both bodies are the same physical form, just from two points in time, any damage dealt to either (including ability damage and ability drains) count against both. However, any effect suffered by one body affects only it as long as the two bodies are separate, but all effects still active on both bodies are added to the time killer’s single form when the Temporal Doppelganger ends.
Temporal Feedback (Su)
By spending an aevum when adjacent to an ally who recently used a limited resource ability, the time killer can grant that ally the use of their ability back. If the ability is limited to uses per day (such as smite evil), the ally regains 1 use. If the ability is drawn from a pool (such as channel energy, ki, bardic performance, or rage), the ally regains a number of uses of that ability up to 2d6 + the time killer’s Charisma modifier (16 for a typical time killer). This cannot give the ally more uses of their ability than their maximum allowed. The time killer can use this ability on itself for recharge the mote of times but not the aevum.
Temporal Island (Su)
As a free action, the time killer can spends 1 mote of time to charge its touch with the ability to block access to the timeways. Once within 1 minute, the time killer can make a touch attack against a creature. If the attack hits, the time killer can interrupt the target’s flow of time, raising the cost for that creature to activate abilities with motes of time by 1 mote for 1 hour. If the time killer spends 2 mote of times, it can use this ability to affect the target’s arcane pool, arcane reservoir, grit points, inspiration, ki pool, or panache points instead of its temporal pool. The effects of this ability do not stack, but multiple hits increase the duration by 1 hour for each hit.
Time
A creature with the time subtype has some connection to the Plane of time. They exist outside the normal flow of time and often age differently, sometimes not aging at all and other times actually aging backwards. They are immune to spells and effects that affect time. They also possess the following trait:
Foresight (Su)
Creatures with the time subtype are able to see a few seconds into the future preventing them from being surprised, caught flat-footed, or flanked. It also grants the creature an insight bonus to AC equal to its Wisdom bonus. This ability can be negated, but can be restarted as a free action on the creature’s next turn.
Time Break (Su)
When the time killer confirm a critical hit with its slam or a creature fail (or renounce the save) the Reflex save of trample, wild temporal energies risk moving the creature through time. The creature must make a Will save DC 45 or be hurled in a different time of the time killer choice. The time killer usually move the target millions of years in the past, when the planet was still a glowing ball in formation or when it didn't yet exist for the creature to die simply due to the hostile environment. If this is not enough to eliminate him, the time killer with sense the fracture can simple follow the target for finish the work. The save DC is Charisma-based.
Time Consummation (Su)
A creature or object that fail the saving throw of the chronal cannon must make a Fortitude save DC 45 or advance to the next age category. The target immediately takes the age penalties to Strength, Dexterity, and Constitution for its new age category, but does not gain the bonuses for that category. A creature whose age is unknown is treated as if the spell advances it to middle age. A creature advanced beyond venerable is disintegrated by the flow of time. Object, construct, undead, ageless or immortal creatures takes instead other 20d12 points of damage as time weathers and corrodes them if they fail the Fortitude saving throw. The save DC is Charisma-based.
Time Cross (Su)
The time killer can focus its timeline-stealing powers on a target, and steal from it a moment of success. It spends an aevum to make a ranged touch attack against any target it can see within 100 ft. + 10 ft./time killer HD (480 ft. for a typical time killer). If the time killer misses with this ranged attack it can try again (with each new attempt being its own standard action) for up to one minute per HD. Once a target is hit, as an immediate reaction, the time killer can force the target to re-roll a single attack roll, damage roll, skill check, or saving throw it is aware of that occurs while the time cross is active (a time period equal to one minute per time killer HD). The target must take the result of the second roll. After the target re-rolls once, the ability is discharged regardless of the outcome of the re-roll.
Time Dilation (Su)
The flow of time is distorted around the time killer. The time killer can take twice as many actions during the round than usual.
Time Runner (Su)
The time killer can move briefly through time, taking an action that does not exist in the normal sequence of reality. The time killer spends two motes as a free action to gain an additional move action. The time killer does not set off alarms or traps during this move action (though it may cause them to be triggered if, at the end of its run, the proper triggering situation still exists). It does not provoke attacks of opportunity during this move action, nor may other characters make Perception checks to notice the time killer during this move action. After the move action time catches up to the time killer, allowing triggered traps to go off and other creatures to immediately notice the time killer where it now stands.
Time Shift (Su)
When the time killer uses greater teleport, interplanetary teleport, or plane shift, it can arrive precisely at its decided location at any time in history (it can use them to transport other creatures to different points in time). Also, the time killer can use its plane shift spell-like ability for travel to and from the Dimension of Time.
Time Zone (Su)
The time killer generates a bubble of time-altering energy that slows existence around it. All of existence within 90 feet of it is paused from reality, allowing the time killer to act instantaneously relative to the reality outside of this area. All of reality within the bubble progresses as normal, allowing combat, exploration, and general life to continue normally. From an outsider view, this is perceived as all of the events within happening quicker than an instant and usually missed by outside creatures. This does not count as timeless for the eternal ability.
Unmaking (Su)
An opponent selected with magnetar slain by a time killer is unmade–erased from the very fabric of time. No memories or recollections of the unmade creature exist anywhere in reality. Past events the creature was responsible for are now attributed to an unknown–even if they recently took place. For example, suppose a great hero saved a kingdom from certain doom and then suffers the unmaking. The kingdom is still safe, but no one can quite recall who saved it. A creature that suffers the unmaking cannot be raised, resurrected, or restored to life by any means–not even a wish can restore an unmade creature. A creature of demi-deity or above power with the Time Portfolio remember the erased creature, as well any creature with the ability to travel through time. Only the direct intervention of a lesser deity (or higher) with the Double Time Portfolio can restore one who suffers this fate.
(the DM may consider an Epic quest of travel to the dimension of time to recover the shards of the erased creature as a viable alternative)
Will of Time (Ex)
The time killer treats its Charisma score as its Constitution score for the purpose of saves and calculating hit point and gains Reflex and Will as good saves.

Conjuration [Teleport, Time]
Level: Sorcerer/Wizard 9
Components: V, S, M (see below)
Casting time: 1 round
Range: 30 ft.
Area: Special
Duration: Special
Saving Throw: none
Spell Resistance: none
Upon casting this spell, a shimmering golden portal appears somewhere close to the caster (though the caster has no idea where the portal appears). The 10-foot circular opening appears to lead into a long tunnel filled with silvery-blue flashes of light. Creatures that gaze into the tunnel for more than one round begin to see glimpses of their past cascading past the walls of the tunnel, though these memories cause no damage. The portal remains for one round per level of the caster or until the caster enters the conduit, whichever occurs first. During casting, the caster names the age and year that the time conduit is to transport those who enter it. This spell allows travel only to the past, never to the future. For example, a wizard who wanted to visit Thassilon around the time of the schism berween the Runelords would state: “During the Age of Legend, in the year -1650 AR.” Items that do not yet exist in the time are removed. Stripped items are stored in the conduit and are returned during the voyage home to the time travelers (but the return trip likewise strips travelers of items they have collected during their stay, creating a storehouse on each end of the conduit where time travelers can leave their belongings). Spells that do not exist in the current age appear as blank pages in a spellcaster’s spell book and spontaneous spellcaster (like bard and sorcerer) cannot cast them. Scrolls that do not yet exist in the current time are likewise blank. Blank pages return to normal when the time traveler returns to his own time or when the spell becomes available during his stay in the new time (such as by it being created during the year in which they’re in the past). There is never a way to determine the precise destination when using a time conduit spell. The only thing for certain is that the time travelers appear somewhere in the lands that they seek. For example, travelers entering Thassilon might appear in the southern city of Xin-Eurythnia or they might appear as far north as Xin-Shalast. Time travelers always arrive during the festivities celebrating the new year; they always return to their own times during the final night of the year. Nothing can prevent a time traveler from being drawn into the time conduit at the close of the year, even spells that negate magic or shield against its effects. Upon returning to their own time, creatures discover that one month has passed since they left (though they have still aged one full year). Items obtained during time travel (including spells written on the spellbook), are not carried over to the present and are left in the past. Also, time travelers can not exist more than once in a particular time: once a traveler time-travels to a particular year, he can never return to that year again. Any attempt to do so simply fails. The material components for this spell are three scales from three differently aligned great wyrm dragons (one from each), the dust from a slain royal time elemental (Tome of Horrors Complete), soil from the destination land for the time conduit spell, and knowledge of the age and time to be visited. The physical components are consumed during the casting (the knowledge remains).
Special: Time Conduit is different from standard spells. A spellcaster gains access to Time Conduit only by uncovering its secrets in some other way. Some are guarded by jealous archwizard, while others are lost in missing libraries or molder on forgotten scrolls.
A campaign in which modern-day heroes travel back through time to a past age carries with it more than just the knowledge that the player characters bring with them. Fortunately‚ travel back into past is jealously guarded by the Overgods that carries the portfolio of time. They understood that time traveling would become an interest to spellcasters at some point. Instead of allowing spellcasters to come up with their own methods for time travel, they took it upon themself to establish how magic and time travel could work together. To this end, they created the time conduit spell to allow travel through time on their terms. Wizards who sought to create new spells that evaded the rules of time travel inevitably failed, their research leading them back to the conclusion that their time conduit spell was the only way to time travel. Its drawbacks, however, made it nearly impossible for time travelers to alter history (which, for many spellcasters, was the only reason to time travel).
The decision as to allow player characters the ability to alter the timeline is left in the hands of the Dungeon Master. The official timeline remains as detailed, assuming that player-characters were unable to make. Spellcasters and their companions who traveled back in time always arrived at the start of the new year‚ and they always left on the final night of that year. Nothing‚ not even anti-magic field or wish prevent the magic from pulling a time-traveler back to his current time. Armor and weapons that didn’t exist at the destination likewise couldn’t go with the time traveler. Spell books and scrolls could go back in time, but spells that don’t exist at the destination time simply appear as blank pages (such spells reappear when the time traveler returns to his own time). The time conduit spell, is an extraordinarily difficult spell to obtain; researching the spell could take many years. Abilities granted by a god in one time might not exist in the destination time period: the deities available in the past were few‚ compared to those existing in modern-day. Clerics‚ paladins‚ and inquistors of a deity who arrive in the past from the distant future find themselves in one of two positions. The first possibility is that their patron exist in this moment of the past. If this is the case‚ the follower loses only those spells that do not yet exist in this moment of the pasy. Divine classes that arrive during a time that their god didn’t exist lose all of their ability (like if thei become an ex member of their former class) until they find a god to worship. Since they are time travelers, Ouroboros (a great, great, great wyrm cometary dragon, Divine Rank 64, as a Demiurge Stage II) and Yog-Sothoth are willing to provide spells to them (since time travelers are technically part of their portfolio).
