I guess we could. They don't have an awful lot of depth, but that's not a problem. I know I could play Gallus at least. If you're referring to picking one of Sabine's friends rather than specifically a scholar's loft colleague, then I would ask that you play as that character. Playing all of Sabine's friends gets boring. I'd rather more of Sabine's interactions be done over posts rather than me writing all of it.
