Subrace: Sea Elves

The sea elves fell in love with the wild beauty of the ocean in the earliest days of the multiverse. While other elves traveled from realm to realm, the sea elves navigated the deepest currents and explored the waters across a hundred worlds. Today, they form small, hidden communities in the ocean shallows and the Plane of Water.
