Tolk (Tol)
Tol(y)k is the paramount sea spirit of the Nivkh of Sakhalin and the Sea of Okhotsk coast, appearing as a sea serpent or whale with scales shimmering like dark water, or as a towering humanoid rising from the sea. Mercurial and powerful, it controls the sea's bounty—generous when respected, capsizing boats when angered. Its cult reflects the centrality of sea-mammal hunting to Nivkh life.
