As shown here, arcane magic does not exist. Therefore, any arcane class is not allowed except for Bard, who is now spirit based. I will absolutely entertain theme changes to other characters if they make sense, but wizard/sorceror are full out, no matter what.
In addition, the Primal power source is now known as Spirit. The connection to the Spirit realm is what powers those classes, items, and effects.
Shadow is still Shadow, though it does not connect to the shadow plane, which does not exist. It connects to the Spirit Realm.
Divine classes do not necessarily need to pick a god to follow specifically. But they absolutely can if they wish.
Teleportation effects originate in the Fey Realm. Teleporting will technically bring a character through the fey and back into the prime.
