Okay, so I will go with Obsidian magic, and the main reason I suggest some kind of summoner magic since Legion magic is a thing I saw on the wiki. Though that is more chess pieces, and now that I think about it, it's a bit strong, so yeah, Obsidian magic for me. And for the exiled bit, I just wanted a reason why a Hino noble is living in Clover. But either way, expect a cs soon.
