Okay, so I've gone and made two avatars.
Shathash, and Shathash Unmasked.
The vast majority of the time Shathash is in masked mode. He pretends to be a horribly burned, drunken/addict half-orc necromantic caster of very dubious personal grooming.
Shathash unmasked is a cold, meticulous plotter.
I'm guessing most people are not going to know Shathash unmasked. If there is someone who would be comfortable hanging around with an undead then tell me!
Otherwise Shathash is mostly going to pretend to be that drunken caster I mentioned above.
He needs cash at the moment and will take jobs for that reason.
He's very gullible (doesn't understand emotions) and would be very happy to hang out with those who are good with people.
Krixus: Shathash actually speaks quite passable orcish. Interested in a "half-orc" workmate? He's weak for a half-orc, but tough - and he's got magic when you need it.
