Ishiar (pronounced IH-shee-ahr) is the great underwater Abyssal realm of the demon lord Dagon. Teeming multitudes of terrifying aquatic monsters haunt its lightless depths, but none is as fearsome as Dagon himself. He resides in a sunken city called Ugothanok, sending out his minions to the oceans of Golarion to wreck havoc and spread his foul seed. The demon lord Gogunta's realm of Mephizim lies on a huge, marshy island on the surface of Ishiar. Compared with Dagon's realm, however, Mephizim is tiny in comparison, and the Shadow of the Sea is content to let Gogunta conduct his blasphemous rituals there.
