An island in the Unnamed Sea west of The Shield formed from a large chunk Portund during the final battle of the War That Ended the Peace. The hole where the land was sitting before formed the rich Portunian Valley.
It turns out that the underside of Portund (which was just barely not a desert for most of its history) was incredibly rich and arible, so the island quickly grew lush vegitation of all sorts.
A collective of Sleep Elemenstors took up residence there, building a small village dedicated to the advancement of the manipulation of the Sleep Element. These Elemenstors of Horth became well known in the practice of their craft and when the Unlight War broke out, they were called upon to bring their mighty Bedding Golems and assist the Elves int the battle against the Vampyre scourge.
