Author has written 8 stories for Magical Girl Lyrical Nanoha, Black★Rock Shooter, Bloodborne, and RWBY.
For RWBY fans, I now have a Tumblr account (sunder-the-gold tumblr com) where I post articles about the world of Remnant. I'd link it here, but FF.net apparently doesn't like that.
Originally, it was just Semblances: those of the canonical characters, those for characters crossed over into Remnant, and those for completely original characters. If you have a hard time coming up with a really cool Semblance that seems like it might fit in with the others, come on over, ask a question, and browse what's available. I don't even mind if you borrow ideas, though I prefer getting whatever credit is due.
But I've also written a number of articles about Aura in general, the Grimm, Dust, the Four Great Kingdoms of Remnant, and more.
