Solomon Drake, here. I really like the distinction between the two, not just because it gives players something more to strive for, but also grants the opportunity for a unique realm back story!
Weclome to the forums, Drake. If you like the idea, then I encourage you to start up a an RP or two. Even better, if you want to help me generate some content for and refine the Wiki, I think we'll need to have Obia'Syela subpages for both forces
