I actually not care what art they are. The "Art" I think is a later came up and very subjective definition. I m more into their personality, I will talk to them first, and let all of my companions know we going to have a new friend soon. also I would individually connect with them to feel is they happy and fine about it. So far I haven't got an NO. but so make sure, I would give house rule, and tell them we all big family, please loving each other, for me, never cause harm to each other. As far as I know, they all are highly intelligent being, I think they won't just punching each other for I don't like you. And yes, I got angel, and demon in the same house. They are actually fine to work together. They are just different being, but not againsting each other. but of course, ask the conjurer first would be nice. I got some spirit from few other conjurer I trust, but that before I fully devoted myself on the Dark path. Now I m totally devoted myself to Akelta, as she is so nice and lovely like a mommy
