Ambrosia is fey, and is the only other one in the group who isn’t humanoid, I think.  I’m hoping that doesn’t get house-ruled, since that was the overwhelming majority of my reasoning behind making Gorun a monstrous humanoid race to begin with.  I would’ve just made a gnoll and not even worried about putting a race together, otherwise. Even so, there’s still the spell resistance (which, granted, is low, but still needs rolled for).
