Poseidon

Poseidon was a god of waters worshiped by some in Impiltur in northeast Faerûn. However, like the sea, he was fickle in nature.

History
In the late 1350s DR, twelve clerics of Poseidon served aboard Rilaunyr's Warship, which was based in Sarshel. Their duties were to heal the crew, provide supplies, and update Lord Rilaunyr on the current state of the sea and Poseidon's attitude.
