Mer-People
Mer-people live in the ocean of Dreamland primarily in the city of Naroobi. There are both mermaids1 and mermen. They have a mostly human torso attached to a dolphin or fish like lower body. There is a wide variety of types for each half of their bodies. They are able to cast a spell to give other races mer-people attributes2 until the visitors return to land which causes the spell to end.
They have long had a friendly relationship3 with the elves who frequently trade with them using the Naroobi Shell to aid communication. Specifically, the Mer-king is close to Oberon Ashenheart and Titania Ashenheart and was one of the last people to see them before their disappearance.
