The Maelstrom World is a world infected by the Malestrom.
It looks like all the major worlds combined into one Stromling-infected world. Even some Space bases, but wrecked, appear in the hills. The Darkitect's Lair is in the center of the Stromling Circle. There, players could defeat the Darkitect's right-hand man, Ampthro, and access the unreleased Darkitect Instance.
