Half-Elves

Elves continue to interbreed occasionally with their human trading partners, and half-elves have similar status in both societies as they always have. However, half-elves often find they fit in better among the mongrelfolk than they do in either elven or human society, and often join mongrelfolk crews or move to Gus when they’re old enough to leave home.
