Seycha's bay is a large body of water surrounded on three sides by land which connects directly to the eghean sea. It is situated on the west coast of East Eghea just below the center of the western coastline. The ghynzuan capital Miraiy lies on the eastern shore of the bay.
Most of the bay's shoreline is made up of beaches. The only exception is found on the northern shore where tall cliffs rise up out of the sea. To the east land rises up slowly at first, then steeper until it eventually meets the [name] Flats.
