These mansions are buried in the hills beyond the Rivers of the Dead. Legend has it that the mansions were built before the Inland Sea was formed. They were buried when the massive earthquakes created the Inland Sea by sinking the land to the west. It is said that Ut-Napishtim prophesised that the land would be destroyed due to the depravity of its inhabitants. Others believed that he himself brought about those earthquakes and floods and so became known as the Keeper of the Waters of Retribution.
