Still the weave. I decided not to rewrite how magic works.
Correct.
Homebrew crystal sphere, don't really feel like making it into its own independent universe yet. The Protigonus make spelljamming in or out near impossible, so it is isolated from the other spheres.
The Nawiht started as a fusion of the Astral Plane/Sea and the Shadowfell. So any spells or abilities that would normally be associated with one of those places is now associated with the Nawiht.
Current plan takes us to level 14, possibly 15 if we wander off on a large side quest. I like the idea though.
I like the concept. Right now it mostly comes across as an aesthetic change, we will want to add a bit more to it. What happens if the character goes too long without a dose of fey food?
However, keep in mind that one spot is reserved for my friend Charybdis1618 who is playing a wild magic sorcerer (in full plate), so if enough applicants finish making characters I might not choose a wizard for the sake of having a well rounded party. Currently there are only 5 players that have done more then roll stats so it might not be a problem.
