Salmire

Far from the star Salmire is a small moon whose surface is completely covered in a deep ocean. The planet is warmed by the constant volcanic activity that keeps the water temps world wide at near 80 degrees. The tropical marine life has adpated to the low light levels by generating their own making the light from the oceans brighter than that from the sun. The humanoid inhabitants live on floating cities and a group of aquatic elves live in stable regions under the seas.
