An alternate timeline of the Raiders Universe. After the bombing of Nagasaki at the end of World War II, a grieving mage, his whole family dead, wandered into the blast zone and cast a death curse, its power amplified by his rage and the weakening of nature there. He cursed the world so that each generation would turn upon its elders, becoming worse than the last.
In the 1990s, a desperate group of mages tried to summon the Raiders; they pulled in Constellation instead. He beat back that world's Lord Ebon (who profited from the curse), traveled across the Astral Plane, and recruited the Raiders after a typical Superhero Misunderstanding Fight. Together, they managed to defeat Ebon and lift the curse.
The Curseworld contained alternates of both LNH characters and LNH Writers, including Brian Perler, Victoria Fike, and Percival Happersen. The Curseworld version of Constellation eventually migrated to 000SUPERGUY.
