Out of curiosity, how would it be handled if, in a character's role, his stated goal for joining scion was to mooch their benefits and give as little as possible in return? Sounds like believable RP for an evil character.

Obviously the archmage, scion imms and scion members would be outraged if this player's true motives were to be exposed. Should imm-tervention be required to expose these motives, though, or should it be left to the scion mortals?
