The Sunrise Sea from the eastern coast of Ya'ardamat.
The Sea of the Rising Sun is the world's easternmost sea as far as scholars know. Though scholars know that the world is round, the exact size and span of the Sea is unknown. Many attempts have been made to traverse it, but none have found its conclusion. It seems to be an endless expanse of ocean, not even dotted with a single island.
Violent and harsh storms are common in the Sea, making it nigh-impossible to traverse safely. Most adventurers who have attempted to cross the Sea have perished to storms before they even had time to run out of provisions and starve.
Sailors' legends tell of a cursed land at furthest east of impassable forests of dark rot, fungus, and blood magic. These lands are unknown to exist, as no man has ever seen them and lived, which naturally begs the question of how the legends exist at all. Some believe that Furthest East is a land of Apollyon, while others believe that it may be the primordial world before Bouwen and the Worldshaping.
The Sea is covered by the World's Eye, a gigantic and violent hurricane which has raged for all of known history. Inside the Sea resides the Storm Giant.
