Deenja is the holiest place in Zambaso. It is guarded by freshwater tritons who see it as their sworn duty to protect this place.
It is a ruined city from ages long ago, back when the gods still roamed the planet and this was said to be their last home before they took their place in the sky.
It is located on an island in the middle of a great lake, Pel-Holina, which bears three rivers out to sea.
