As long as the Mark isn't the thing that turned them into Beastmen, it's perfectly fine. And Seraph is the closest thing to a GM that there is when Halvtand and I aren't around. This is the final verdict: As long as the Mark is an actual Mark, Aristo's characters can stay the way they are. Find something new for the Mark to be, and have them get cursed into becoming Beastmen through some other means. Conversation over.

Parker, I'm grateful that you paid attention to all the rules and minor details. As I said before, your mind works like mine and Halvtand's. xD But that side, just let Aristo either agree to, or disagree to the conditions I have applied.
