The Cursed One was a being bestowed with the curse — visions —[1] and prophesied by the Covenant of Trombli to arise to restore the monarchy in Pylea as their princess.[2] The Cursed One was meant to com-shuck with the Groosalugg as a mating ritual[2] so her visions would pass to him.[3]
The Cursed One turned out to be Cordelia Chase,[1] who refused to gave up her visions and left Pylea; however, her last act as princess was to abolish slavery and appoints Groo as the new ruler of Pylea.[3]
