Well, technically characters are supposed to be self-inserts but you can also just have the character personality take over and essentially play something canon or a non-self insert OC.

I may or may not, it's harder to fit them into this setting.

Also, how, how when you actually stated one of them was YOU and this entire roleplay is centered around self insertion. That character is pretty much built around the concept beyond the whole "use your forum avatar" thing that can be readily ignored. As an aside, I think your attempt at having godly metamagic that totally lets you shut down magic but isn't magic itself and having vampires with no meaningful vampiric characteristics beyond sucking blood is fairly awful, but they'd still fit into the game rather easily.
