My Shifter "Night Bane" was recently accepted into a game, so he'll be taken for a while. However Kane the Human Hexblade is still up for some gaming.
Like most Hexblades, Kane realized the magic side of his powers at an early age of 6. After he and his mother moved to waterdeep, his powers began springing forth at a rapid rate. He was enrolled in martial arts schools, and by age 11-12 could take down most adults in his academy. His hexblade powers grew at a normal rate though, since he didn't receive much training in that area.
He has a very judgemental personality. Most Hexblade prefer being with very intelligent and independent people, like themselves. Kane is the same way, except he takes it to the extreme, to the point that he can't function in a party of dependent people, or beings that do not fit his qualifications of being able to live.
