Ulutiu

Ulutiu, also known as The Lord in the Ice or The Eternal Sleeper, is the Lawful neutral father of the giant-kin races and the god of glaciers, polar environments, and arctic dwellers. His domains consist of animal, law, ocean, protection and strength. Ulutiu's symbol is a necklace of blue and white ice crystals and his divine realm is where he sleeps in the Astral Plane.

Worshippers
Ulutiu is worshipped by the arctic Ulutiun peoples of the Great Glacier and the Sea of Moving Ice of Icewind Dale.

Relationships
Ulutiu voluntarily exiled himself from Faerûn when his affair with the giant goddess Othea was discovered by Annam, and he sank into the Cold Ocean and has slumbered ever since.

Auril, the frostmaiden is siphoning power from him, slowly as not to wake him, but she is continually weakening him so that eventually he will die, then she may subsume his portfolio.
