Marahai
Marahai is a crescent-shaped island in the Sea of Jade with no known cities, lying between the Isle of Elephants to the west, the Manticore Islands to the east, and the shores of Yi Ti and Leng to the north.
It holds a place on the atlas's maps because a lord of the Crownlands sailed past it and wrote it down: without that account, it would be little more than an outline on the chart of the Jade Sea.

Two volcanic islets rise in its bay, twins of each other, their smoking peaks spitting molten rock day and night without pause.
Corlys Velaryon passed by it on his voyages and set the island down in his letters as a green garden hemmed in by those two burning masses, an image that has outlasted any formal record of the place.
