An immense giant garbed in a yellow robe, fully six times taller than   a human. Its bulbous face is a nightmarish combination of a giant  snail  and a malevolent male human, topped with a crown of four  eyestalks. In  one hand it hefts a massive black mace.
Ythog-Nthlei is an elder horror known as The Dark King by his handful of  aberrant and insane worshippers. He was imprisoned in sorcerous slumber  by a forgotten order of epic-level wizards. Some of the few sages who  know of Ythog-Nthlei fear that lost artefacts or buried temples may  remain that could allow his cult to reawaken him.
 Ythog-Nthlei's cult claim he is billions of years old, older even than    the multiverse (impossible though that be). One infamous poet wrote  that over Ythog-Nthlei's eldritch lifespan  "even death can die", thus  granting him a peculiar immortality. More rational scholars theorize  that   Ythog-Nthlei lives simultaneously in many bodies, and all have to  be   killed simultaneously in order to kill him. The wildest theory  among   sages is that Ythog-Nthlei has para-chronological immortality  and lives   simultaneously at many different 
times as well as places.
Nthog-Ythlei is 36 feet tall and weighs 60 tons.
COMBAT
Ythog-Nthlei is most effective in melee, so uses Dire Charge or 
greater  teleport to engage opponents with his 
Blacklight mace   and bite as  quickly as possible. Opponents outside melee reach may be   targeted by  his eyebeams. The Dark King relishes the effects his  bite's  slave venom  has on foes, especially enemy spellcasters, whose  spells  he often  counters with quickened 
greater dispel magic. If hard-pressed,  Ythog-Nthlei will 
gate in a powerful evil outsider to help, such as a  balor or pit fiend.
If Ythog-Nthlei is attended by a court of priests and eidolons they will    do all they can to assist their master, even if they're little more    than distractions to the Dark King's foes.
Aura of Desecration (Su): Ythog-Nthlei continuously produces a   profane aura that affects all creatures within a 30 ft. radius   emanation. This aura strengthens undead, evil aberrations, evil   outsiders, and any evil extraplanar creatures, giving them the following   benefits:
 
- +2 profane bonus on attack and damage rolls; 
- +4 profane bonus on saving throws and turn resistance; 
- +4 deflection bonus to AC; 
- blocks possession and mental influence as if it were a protection from good spell; 
- All non-evil creatures within the aura take a -6 profane penalty on Charisma checks to turn a qualifying creature; 
- Any qualifying creature created within or summoned into the aura of desecration gains +1 hit points per HD. 
Ythog-Nthlei  is considered a qualifying creature and receives all the  above effects,  including the hit point bonus, and these have been  incorporated into  his statistics.
 
 Ythog-Nthlei can exclude creatures from its aura of desecration,   however it chooses, denying them its effects. The aura of desecration   does not emanate into an 
antimagic field or a consecrated area with an altar (see the 
consecrate   spell). Ythog-Nthlei still gains the aura's benefits within such   prohibited areas, but other evil creatures can not bask in his aura.
 
Beyond Reality (Ex): Ythog-Nthlei is an uncanny being who belongs   to no known plane of existence, but is comfortable in all of them. He   possesses both the Extraplanar and Native subtypes on every plane,  using  whichever subtype is most advantageous on a case-by-case basis.  For  example, he could simultaneously answer the call of a 
gate spell as an extraplanar creature, then ignore that spell's control as a native creature.
Ythog-Nthlei can attack incorporeal and out-of-phase targets without penalty and ignores the effects of 
blink   or displacement powers. He sees all adjacent dimensions clearly,   including the Astral Plane, Ethereal Plane and the interiors of   extradimensional spaces such as a 
rope trick, 
maze or 
portable hole.
Blacklight Mace: This gargantuan weapon is a 
+3 life-drinker heavy mace when wielded by others creatures, but functions as a 
+5 life-drinking heavy mace for the Dark King Ythog-Nthlei. With a swift action, Ythog-Nthlei can command his mace to radiate 
blacklight  (supernatural darkness impenetrable to normal vision and darkvision) in  a 30 foot radius. Once activated, the 
blacklight mace continues to radiate 
blacklight    until The Dark King loses contact with it or commands it to stop    (another swift action). Ythog-Nthlei can always see through this 
blacklight     normally, even if he is outside the area of darkness. Blacklight     counters or dispels any light spell of equal or lower level. A 
daylight spell will temporarily counter this 
blacklight, but the darkness returns as soon as the 
daylight ends.
Furthermore, Ythog-Nthlei (but no other wielder) can command the 
blacklight mace    to summon undead once per day. The mace can  summon any of the   following, of the Dark King's choice: 1 devourer, 1d4+1 bodaks, or 4d6   walking dead. Walking dead summoned by the mace have the Extraplanar   subtype. This is   equivalent to a 
summon monster IX.
Ythog-Nthlei's 
blacklight mace is an artifact, not a normal magic item. It is as fundamentally indestructible as The Dark King himself.
Overwhelming evocation/necromancy [evil]; CL 20th.
Eyebeams (Su): Ythog-Nthlei's eyebeams are 300 foot range ray  attacks (no range increments) that do 1d4+1  Strength damage if they  hits. Ythog-Nthlei can make a single eyebeam  attack as a swift action  once per round or up to 4 eyebeam  attacks as a standard action, but he  cannot produce more than four  eyebeams in a round (one from each eye).
 
Hearty (Ex): When fully healed, Ythog-Nthlei always has the maximum number (8 + Con modifier) of hit points per HD.
Immunities: Ythog-Nthlei is immune  to disease, poison, energy  drain, cold damage and mind-affecting  effects. His Beyond Reality  ability give him special immunity to effects that banish extraplanar  creatures and certain extradimensional effects, such as the miss chance  of a 
blink spell.
Reflect Spell (Su): Any spell that specifically targets Ythog-Nthlei is reflected back onto its caster as per the 
spell turning spell.
Slave Venom (Su): Any living creature hit by Ythog-Nthlei's bite   attack must succeed at a DC 32 Fortitude save or be dominated by the   Dark King for 1d10 minutes. The domination functions like the 
dominate monster   spell. This supernatural venom can affect creatures immune to   mind-affecting attacks or poison, but such immunity grants the victim a   +4 bonus on their save (+8 if they're immune to both poison and   mind-affecting effects, such as a Plant or Ooze). Creatures with saving   throw bonuses against poison or compulsion effects (such as a dwarf's  +2  against poison or an elf's +2 against enchantments) apply these  bonuses  when saving against Slave Venom. Slave Venom has no effect on  nonliving  creatures such as Constructs and Undead. Its save DC is  Charisma-based.

Squeeze (Ex): Ythog-Nthlei's gelatinous body allows him to freely   move and fight through any opening large enough to pass a Large   creature. He can squeeze through openings a Medium creature can fit   through with a DC 30 Escape Artist check.
Transcendental Ythog-Nthlei
Those sages who know of the Dark King have long speculated why the   ancient mages who defeated him put the Old One in an enchanted slumber   and imprisoned him bodily within his temple when they could have   destroyed him with a 
sphere of annihilation or permanently trapped him with 
imprisonment, 
trap the soul   or a similar spell. Some of these scholars came to the conclusion that   Ythog-Nthlei proved impossible to trap or destroy, so placing him in  an  endless sleep was the best option.
If you wish this to be the case with Ythog-Nthlei, add one or both of the following special qualities:
Beyond Death (Ex): Ythog-Nthlei can not be killed. If brought to    -10 hit points his body melts away,  leaving nothing but an  unspeakable  stain, but he will reappear at some  later time or on some  other plane  without suffering any penalties for  having died. He  reappears even if  the his body and spirit are  annihilated. The  time-delay and distance of  Ythog-Nthlei's reappearance  after death is  at the DM's discretion, but  may be considerable (e.g.  1d100 years  later on the spot he died, or  immediately on the lowermost  layer of  the Abyss).
Any effect that permanently incapacitates Ythog-Nthlei or renders him    helpless for more than a month (petrification, being ability drained to    Wisdom 0 or Dexterity 0, long-term paralysis, polymorphing into a    non-combative form, et cetera) is considered to have "killed" him and    triggers his rebirth. Note that sleep effects do not trigger Beyond    Death.
It may be possible to circumvent Beyond Death and permanently destroy   Ythog-Nthlei, but what the means to do this have been left to the DM.   The method is likely to be a deep secret requiring intense research or a   hard quest. Suggested examples are: Ythog-Nthlei will stay dead for   good if he is killed by a creature with divine ranks, a blow from a   lawful evil titan wielding the Dark King's 
blacklight mace,   poison from a creature with both the pseudonatural and paragon template,   or an epic spell that does more than 555 hit points of damage.
Beyond Time and Space (Ex): Ythog-Nthlei transcends spatial and temporal limitations. Any effect that would trap Ythog-Nthlei in time or space, such as 
temporal stasis, 
trap the soul, 
imprisonment, or a 
wish to banish him to another plane will only last for 1d100 days, after which Ythog-Nthlei reappears as if by 
greater teleport or 
plane shift.
Finally, if any creature uses 
time stop within 150 feet of Ythog-Nthlei he can attempt to interrupt the 
time stop as a free action. If Ythog-Nthlei succeeds at a Will save against the DC of the 
time stop, he can choose to have the 
time stop fail or actually enter the 
time stop with the other creature. If Ythog-Nthlei and another creature share a 
time stop they can target each other attacks or spells as if they were both in normal time, but creatures outside the 
time stop are invulnerable to their attacks and spells.
This ability does not hinder Ythog-Nthlei using time- or space-manipulation powers on himself.
Maddening Mind (Ex): Although Ythog-Nthlei is immune to  mind-affecting powers, anyone targeting him with a mind-affecting or  telepathic effect makes direct contact with his utterly alien mind. The  attacker must make a DC 32 Will save or take 2d12 points of Wisdom damage.  An attacker is subject to Wisdom damage on every attempt, whether the  attack is successful or not. The attacker is driven permanently insane  if this Wisdom damage reduces their Wisdom to 0. The save DC is  Charisma-based.

An immense giant garbed in a yellow robe, roughly three times taller   than  a human. Its bulbous face is a nightmarish combination of a giant   snail  and a malevolent male human, topped with a crown of four   eyestalks. In  one hand it hefts a massive black mace.
Ythog-Nthlei, like most deity-level creatures, is able to create lesser avatars of himself. A few scholars fear that at least one Aspect of Ythog-Nthlei may have survived to the present day, trapped within some forgotten temple to the Dark King.
The Aspect of Ythog-Nthlei presented above is intended for use in a 3E conversion of the 
Temple of Poseidon module in 
Dragon #64, since the CR 22 demon lord version is too powerful for the reccommended character level of that adventure.
An Aspect of Ythog-Nthlei is 18 feet tall and weighs 15,000 pounds.
COMBAT
 An Aspect of Ythog-Nthlei uses much the same tactics as The Dark King himself. He has fewer spell-like abilities than a fully manifest Ythog-Nthlei, so is even more reliant on his formidable melee abilities and seeks to engage his opponents in hand-to-hand combat as quickly as he can.
Beyond Reality (Ex): Ythog-Nthlei is an uncanny being  who  belongs  to no known plane of existence, but is comfortable in all  of  them. He  possesses both the Extraplanar and Native subtypes on every   plane, using  whichever subtype is most advantageous on a case-by-case   basis. For  example, he could simultaneously answer the call of a 
gate spell as an extraplanar creature, then ignore that spell's control as a native creature.
Ythog-Nthlei can attack incorporeal and out-of-phase targets without penalty and ignores the effects of 
blink    or displacement powers. He sees all adjacent dimensions clearly,    including the Astral Plane, Ethereal Plane and the interiors of    extradimensional spaces such as a 
rope trick, 
maze or 
portable hole.
Blacklight Mace: This gargantuan weapon is a 
+3 heavy mace when wielded by others creatures, but functions as a 
+5 heavy mace for an Aspect of Ythog-Nthlei. Three times a day, as a swift action, the Aspect can command his mace to radiate 
deeper darkness (as the spell) in  a 30 foot radius (20% miss chance, impenetrable to normal vision and darkvision). Once activated, the 
blacklight mace continues to radiate 
deeper darkness     until The Dark King loses contact with it or commands it to stop     (another swift action). Ythog-Nthlei can always see through this 
darkness      normally, even if he is outside the area of darkness. Deeper   darkness    counters or dispels any light spell of equal or lower level.   A 
daylight spell will temporarily counter this 
deeper darkness, but the darkness returns as soon as the 
daylight ends.
Furthermore, the Aspect of Ythog-Nthlei (but no other wielder) can command the 
blacklight mace   to summon 4d6  walking dead with the Extraplanar  subtype. This is   equivalent to a 
summon monster VII.
The 
blacklight mace crumbles to black powder and evaporates  into  nothingness if the Aspect of Ythog-Nthlei is killed or if it is   separated from the Aspect for more than 24 hours. The Aspect can   recreate a destroyed 
blacklight mace as a full-round action.
