Blair

Shut-in necromancer, research institute basement inhabitant, only works with dead flesh. Hates coming out of his room. Turned himself into an undead to avoid ever needing to come out of his room. 

A child found near-death and almost feral in his parents' basement, until the police discovered and rescued him. Was unable to integrate into the regular school system, and was thus placed into the special schools until his genius and tendency towards experimenting on fellow students became apparent. Then he was taken in by the dark magic branch of the magic research institute, where he became one with the basement. 

Reasonably happy, all things considered. Super unreliable. His familiar Solil does all the talking for him.
