Here is the updated version of the Cydian. I have made a few changes to conform it to the rules and layout of the new edition, removed some unbalanced or irrelevant abilities and adapted it for epic play by making many of its abilities advancable by HD. Since MR Draco has not approved of my alterations of the species it can only be considered partially (80% or so) official.

Combat
Cydians are formidable adversaries and usually vastly outnumber their opponents in any fight they have foreseen.
A Cydian's natural weapons, as well as any weapon it wields, are treated as lawful-aligned and epic for the purpose of overcoming damage reduction. Cydians often use powerful magical items to enhance their performance in battle.
Regeneration (Ex): A Cydian takes normal damage from epic chaotic-aligned weapons, and from spells and effects with the chaotic descriptor.
Quickness (Su): A Cydian is supernaturally quick. It can take an extra standard action or move action during its turn each round.
-Electricity regeneration (Ex): A Cydian regenerates 1 hit point for every ten points of electricity damage inflicted on it.
-Gravity/Magnetism sight (Ex): A Cydian can perceive gravitic/magnetic fields as through sight.
-Cydians can shift between corporeal and incorporeal forms as a free action (Ex). When incorporeal, Cydians are, in effect, great bolts of electricity, and can move at the speed of light, induce electromagnetic fields as well as any other task electricity is capable of.
Electrical Mastery (Ex):
A Cydian gains +5 attack and +5 damage if its opponent's nervous system uses electricity.
Gravity Manipulation (Ex):
A Cydian can manipulate gravity within 50 ft of it with pinpoint accuracy (+/- 300g). This is a free action.
A Cydian is unaffected by gravity levels below those of black holes (singularities).
A Cydian may focus its gravity control to damage another being/thing. This damage is 10d10 unless the target succeeds at a fortitude save DC 39 (10+1/2 HD+Con Mod) for half damage. This is a partial action.
Touch Attack (Ex): The touch of a Cydian can be lethal to unprotected creatures. Should the Cydian want to, it can make a touch attack against a living creature, if it hits, the creature must make a fortitude save DC 39 (10+1/2 HD+Con Mod) or die. This attack has no effect on other Cydians.
All of a Cydian's Electricity based attacks, spells, spell like abilities and special abilities can be infused with Divine energy. Half of the damage of any such attack or ability is therefore not subject to immunities or resistances against electricity, but is considered Divine damage. (Su)
Spell-like Abilities: At Will- Blasphemy, Chain Lightning (Maximised and Empowered), Detect Thoughts, Delayed Blast Fireball (Energy-Admixtured (lightning), Maximised and Empowered), Dictum, Greater Teleport, Improved Invisibility, Haste, Holy Word, Major Image, Plane Shift, True Seeing, Tongues. Caster level equals HD. The save DCs are Charisma-based.
Spells:
Cydians cast spells as a Sorcerer with a level of 2/3 of the Cydian's HD. Most Cydians with cast spells as 20th level Sorcerers.
They may also cast clerical spells, and those from the Air, Destruction and Law domains, as arcane spells.
Cydian Qualities (in addition to Outsider traits):
-Immunity to all mind-affecting effects.
-Immunity to poison, paralysis, stunning, disease and death effects.
-Immunity to electricity (this includes Cydian electricity), cold, fire, acid, and sonic energy.
-Not subject to critical hits, ability drain, or energy drain.
-Cydians do not breathe, eat or sleep.
-Cydians do not age beyond adulthood, though they may advance in HD.
Cydian Biology:
Cydians are basically (and that is vastly simplified) complex sapient electrical charges. Their origin is obviously magical, though magic is not necessary for their survival.
Cydian appearance can be unsettling to mortals. Their native form is that of a ten-foot tall 10-armed human made entirely from a single bluish white spark of electricity. Each of them appear identical to the others of their sex and perfect in form and beauty, their voices are also identical and though they are generally cold and dispassionate they can convey whatever emotion they find expedient flawlessly. Cydians have no difficulty identifying individuals among their own species, though.
Cydians are by nature extremely lawful and hierarchical creatures, though they are individuals with separate consciousness and are very capable of making instantaneous decisions on their own, they are most fulfilled when working for the greater good of their society, following the orders of their superiors. Their industriousness is legendary. Religion is bred into them at the moment of conception, they are mentally and physically incapable of worshipping any other Gods than the God-Emperor and Kas who are revered in almost equal measures, the first slightly above the second.
Cydians are generated by sexual reproduction. The two parents merge for a time into one larger entity, a spherical shape of 10 foot diameter. That entity expands by absorbing electric power from its surroundings and then divides into three individuals, the two parents and a new being consisting of a mix of their pseudo-genetic codes. The speed of the process depends wholly on the amount of electricity available during the growth phase and can last anything from 100 years to 1 second. The electrical output of a dozen Groundpounder Generators is needed for a pregnancy of 1 second, while the natural power generated by the parent-entity makes the pregnancy require 100 years. The speed of the growth of the Cydian into physiological adulthood also depends on the availability on electricity from 1 week to 1000 years, the mental growth into adulthood ranges from 1 month to 50 years.
Since one of the primary goals of the Union of Worlds is to create as many Cydians as possible and since electricity is very easily generated there is rarely any shortage of electricity, and never any shortage of Cydians.
