Ossorus

Ossorus was a beautiful underwater city in the religion of the Gungan species on the planet Naboo. It was believed to be the home of the Gungan deities known as guds, including the chief deity Oma-Oma. The god of destruction, Mekamok, also lived in Ossorus even though he was considered the only gud outside of Oma-Oma's authority. As such, the other guds avoided him.

According to legend, Ossorus was protected by Balam, the first Gungan warrior. Upon Balam's death, Oma-Oma took him to Ossorus and granted him immortality in exchange for teaching the other guds the art of warfare. Balam also created the city Otoh-D'in, where the bravest Gungan warriors arrived after their deaths. The legions there were pledged to defend Ossorus if it ever came under attack from Mekamok and his acolytes. The Gungans also believed that Ossorus was protected by enchanted sando aqua monsters and giant Gungan warriors atop loyal kaadu mounts.
