Just a quick comment: Surely if there's no light she can't use ANY light magic? Not just the more powerful techniques? I mean, you manipulate actual light.

Also the more I think about it the more glad I am you aren't in a guild.

Two of Necropolises three members gets countered by sage magic since the third rule doesn't apply. It's kinda spooky. Although I assume a fight between Phoebe and Rucks would be interesting if sage magic happens. They both do kinda the same thing, literally bending the fabric of existence to fight other magic.
