Name: Esra Sheillkar
Age: 431
Sex: Female
Status: Chaos Sorcerer Lieutenant, Delta class Psyker
Looks: Thin and pale, with abnormally odd color hair, Esra seems like a frail, fragile creature. She has no tattoos, and no insignia of any kind, binding her to any one flavor of fell power, but she writhes with pure psychic energy. Her armor is light in comparison to a Chaos Marine, but effective against most human firearms, the black leathers plated with ceramite underneith. She carries no guns, and instead depends on a force sword capable of extending itself with chain links, controlled by her psychic powers.
Wargear: Ceremite leathers (Equivilent to Best quality Xenomesh armor), Tal-Faern the Living Blade (Force sword capable of extending itself similar to Ivy from Soul Calibur's sword), Best quality Photo-contacts, Vox bead, Gruesome Talismans (Chaos Charms)
Bio: Esra has been a prodigal psyker all her life. At the age of 5, she was taken by the Black Ships to train her to become sanctioned, but the ritual could not hold. The Powers that Lie Beyond forced the sanctioning ritual to appear to bind her, and allowed her to train as a young girl. She quickly became very powerful, the Primaris Psycana eventually decreeing her too powerful for her own good, and tried to have her killed. All that remained of the anti-psyker kill team had to be removed with high pressure hoses from the walls and cielings of the complex.
Many centuries have past since then, and her power has only grown. Dealing with various Empyrean denizens, and the Powers themselves, she has decided to play as a neutral party, a mercenary to all sides.
Fighting Style: She uses her telekinesis powers to block, disable, maim, and otherwise force people up close to her, where she then unleashes Tal-Faern the Living Blade.
