I've been GMing for so long, I've been itching to get back to playing and I can see this has potential. I've made a skeleton thing of a CS but there's more info I need that I can't really get from the Information section:
1. What exactly is the Arcana Demense? Like the Mages Guild or something akin?
2. Is there an age of adulthood? Can anyone under said age be an adventurer?
3. How old are the Divided Kingdoms? Are they varying ages?

I've GMed a couple of games IRL and on this site before the legendary crash of Xmas 2013. Like I said above, I can see potential and, if you'd like, I can help you flesh out some aspects of your world. Ain't trying to hijack, really wanna jump back into a PC.
