*points to the crescent moon mark on his head* judgeing from the placement of the crescent on his head and looking at it in conjunction with the lunar cycles... Starrk would be either a waxing or waining Theurge. The Crescent moons' abilities to speak with spirits and converse with nature make them likely members for ghostly councel.... details are below:

waxing theurges are ones who are usually the ones who offer up sagely councel and honorable partnerships to spirits when they make fetishes.

waning theurges are more duplicitous in their nature, teaching others by "round about" spiritual logic and sometimes binding spirits into fetishes by coercion, blackmail or otherwise unsavory methods.

anyways, if you are going by his namesake, I'd make him more of a new moon or a gibbus moon. regaurdless, he still should have those two fetish firearms you talked about earlier.... you know. the ones that make with the pew-pew laser talons that have firefly spirits bound into them.....
