Ezku (pronounced EZZ-koo) was a sprawling Itothani locatah reef-city within the Wonder of the Seas. Like most other large Itothani settlements, its population was highly diffuse, the city stretching across many miles of the reef. After the initial demonic invasion of the Old Twins, Ezku was the first aquatic settlement to be attacked. Though its inhabitants fought fiercely and valiantly across several demon-seasons, the survivors were eventually forced to abandon their homes, the fragments of the Wonder of the Seas they took with them some of the only living remains of the reef now known as the Corpse.
