Sea Elves

The Sea Elves are an aquatic race who are similar to Elves, but live in the sea. Some biologist somewhere must have worked hard on that one. Like most aquatic species, they have been enslaved by the Kua Toa, for whom they often serve as emissaries, due to their resemblance to (and hence lack of revulsion from) terrestrial humanoids. The only Sea Elf encountetred thus far has been Rollo, who was clearly capable of at least limited amphibious breathing, a rarity among the extant non-Kua aquatic races.
