Maveren as a playable race

Homebrew

Maveren (mixed human and sea elf)

Technically, Maveren is a social/cultural identity, not a racial one; it’s possible for anyone to become Maver (though it's hard, and hasn’t happened in more than a hundred years). However most Maveren are descended in part from the original settlers/raiders, who were of mixed human and sea elf heritage; also, there are some people with sea-elf ancestry in Malfa who are from families that stopped being Maver years ago. Some of them are Maveren's thralls.
