  • Naiads, Nereids, Nerites, Oceanids

All are from Greek mythology. Naiads are water nymphs of rivers, springs, and waterfalls. Nereids are 50 daughters of two water spirits. Nerites are the brothers of the nereids. Oceanids are the three thousand daughters of the Titan Tethys, and each was the patroness of a particular spring, river, sea, lake, pond, pasture, flower, breeze or cloud. They look mostly human with normal legs.

  • Merrow

They're an Irish myth. Look a lot like mermaids because of their fish tails, but they have a distinguishing magical cap. If the cap is taken out of their posession, the merrow is obligated to follow the new owner's orders until they can retrieve their cap.

  • Selkies

Selkies are from Irish, Scottish, Faroese, and Icelandic folklore. They can transform between a human form and a seal form by shedding or donning their seal skin much like a coat or a wetsuit. Much like the merrow, if a selkie's skin is stolen, they cannot return to their seal form unless they retrieve it and must follow the thief's orders until they can retrieve it.
