hey, i'm thinking about submitting one of my fantrolls, who has a slight mutation (shared by her lusus). She has the troll equivalent of vitiligo, patches of her exosketeton is a darker shade of grey, and her lusus is a white tiger, with not black stripes, but a very light grey. would that be okay? ((also how do you guys feel about cannibalism?))

Vitiligo is fine! As for cannibalism it's technically allowed as a character choice, but it's about as taboo on Alternia as it is on Earth. It would only be disallowed on a meta level if it severely impacts a character's ability to play with other members trolls, or if it strays into godmode territory (offhandedly serial killing a bunch of NPCs with no repercussions).
