Talassar

Talassar is Ultramar's storm ocean, a world of rock islands and one continent, Glaudor. Word Bearers hit it in the Shadow Crusade, Night Lords later occupied Castrum Velx and stole gene-seed, and Cato Sicarius still takes his ducal title from its nobility. In 999.M41 Calgar destroyed the daemon prince M'kar on its shores, and the Void Tridents of the Ultima Founding now call it home.
