Fey Touched, a D&D 5e homebrew origin for sorcerers

My next offering to D&D homebrew was supposed to be the half-elf variant I’ve created, but I’m still working on getting a good balance between human, elf, and half-elf abilities. The half-elf variant started out as the result of a specific historical event in my homebrew campaign, so I’m also trying to strip out the specifics to make a version that can work in any campaign setting.

So instead of a race variant, this time I present an origin for the Sorcerer class: Fey Touched.
