Dolphin

Dolphins were plentiful in the waters of Abeir-Toril.

They were the allies of the aquatic elves and particularly old and intelligent dolphins could be found living with them in Myth Nantar. Dolphins were sacred to the elven god Deep Sashelas and the deities Istishia and Valkur.

Bay of Dancing Dolphins
They could be found in the Bay of Dancing Dolphins in Dambrath where they could be seen performing the Dance of the Dolphins every evening at dusk. This display would attract spectators from all around Faerûn. The locals thought the dolphins were responsible for the calm waters of the bay. They were allies of the triton that lived in a hidden underwater city.
