Maiar of Ulmo, The Lord of Waters
Ulmo is the Vala responsible for water and was a close friend of Manwë. He was one of the Aratar, the eight most powerful Valar, and it was said that Melkor feared him almost as much as he feared Varda because the sea could not be tamed. Ulmo had dominion over all water on Arda, including the waters that flowed beneath the earth. His palace called Ulmonan was located in the bottom of the ocean, and he maintained contact with Middle-earth through rivers and streams.
Ulmo was served by multiple Maiar including Ossë and his wife Uinen, who were friends with the elves that dwelled along the coasts. Another Maia who served Ulmo was Salmar, who was in charge of Ulmo’s great musical shell-made horns, the Ulumuri. Additionally, a primeval whale named Uin is mentioned as a servant of Ulmo in Tolkien’s early works, though it’s status as an Ainu is unclear. The "River-Woman", the mother of Tom Bombadil's wife Goldberry, is also speculated to be a servant of Ulmo based on the fact that she is a watery entity, though her exact nature is unclear.
