The Soul's End Islands are an archipelago far to the southwest of Meklaw, poorly mapped and unknown to most of the world. The tengu pirate Andan Cuyucha reached the islands with a small fleet in Y9777*, and many who attempted to find him later ended up stranded there as well.
Until Y9976*, the nascent demon lord Huzrotho was entombed under the Refuge, one of the islands in the archipelago.
