Lady Styx's origins are at this time unknown, though the Guardians of the Universe (clearly distressed by her presence) believe she originates from somewhere outside the known cosmos. Worshipped as a goddess by her followers, the Lady sends forth her legions to ravage planets and transform their populations into her undead slaves. This is known as the "Stygian Passover". In her twisted mind, this is a way of bringing order to a chaotic universe, uniting all peoples as one race with a single purpose, the worship of her.
