A surface elf that praises the dragon god. Good. Haha.
Bears everywhere. It'll affect things, gonna make a bear Hunter.
Magic is pretty varied, there is virtually no limit to what you can and can't do, except super powerful stuff. Also that, I'll probably change as far as dark magic, that was just a hold over from before. So if you want a elf that does some dark magic stuff, cool. Also yes, mostly necromancy and poison type stuff.
Currently yes, those are the only outward using magic types, well, goblins and dragonoids too.
And paladins are allowed. Not a lot is restricted as far as classes, except no well trained warriors and mages, whose whole life has been one war after the next. At this point, they have some training due to the circumstances, but in the beginning they were fucked.
