The Terminos Ocean is the largest and most expansive body of water in the world of Abmarah, a vast expanse of seemingly-endless ocean that stretches as far as the eye can see. The ocean is known for its deep blue color and powerful currents, which can be treacherous for even the most experienced sailors. Despite its size, the Terminos Ocean is relatively devoid of islands, with only a few scattered throughout its vast expanse. 

Only experienced sailors have dared to cross it, using the few islands the ocean has as stepping stones to cross the divide between Eteru and Eqos/Teer. This is the only known safe route through the ocean, as the distance alone makes it difficult to cross anywhere else. The Terminos Ocean does have one pocket of civilization all to itself, being the island of Te Motuaotea.
