THALASIA

The source and destination of the River Oceanus is Thalasia, Elysium’s fourth layer. Thalasia is a mighty ocean, deep blue and dappled with sunlight at all times, with hundreds of beautiful and bountiful islands dotting its surface. Many of these islands are the home to heroes and kings enjoying a final rest, some waiting for the day to be called back to the Material Plane, while others simply enjoy an eternity of restful solitude in a paradise of golden beaches, sweet fruits, and merciful skies.

Below the waters, Thalasia is just as beautiful. Several colonies of tritons and sea elves from the Plane of Water rest in great coral reefs, and the relatively low number of predators in the azure waters makes it easy for the fish to grow to enormous proportions. Luna jellies that rise up from the River Oceanus on all layers are said to originate in Thalasia, in the nest of Hhallashaa the great luna jellyfish of the sea.
