Many years ago, a highly advanced society known as the Lightning Lords found themselves the target of an invasion by two rival factions of aliens – the Mygorg and the Yorg. The Lords consulted with their sentient computer network, an artificial intelligence they dubbed The Keeper. The Keeper advised its charges to postpone military action against the Mygorg and the Yorg until they could learn more about their weapons strength. After analyzing the situation, the Keeper suggested that the Lords should continue to maintain a false front of neutrality, and chose a sorceress named Lady Djinn to act as a faux queen, while the true nobles went into hiding. The Lords trusted Lady Djinn to work in their best interests, possessing little idea of the woman's true power and ambition. She used her dark magic abilities against the Keeper system and turned its primary programmer into an addle-brained, mute. With the Keeper under her command, Lady Djinn became the planet’s true ruler.
As years passed, Djinn allied herself with the Yorg and maintained her position of power at the Lightning Lord citadel. The Mygorg meanwhile, took control of the surrounding valleys and began enslaving its human populace.
A warrior woman known as Starfire discovered the former computer programmer and freed him from his Mygorg slavers. Ignorant of the man’s history with Lady Djinn, she named him Thump, and invited him to join her band of rebels.
Starfire and her warriors began leading raids against many Mygorg camps and Lady Djinn recognized that her movement posed a threat to her control. She had Thump captured and brought back to the citadel. Starfire mounted a rescue mission and broke into the tower to free her friend. Lady Djinn and Starfire faced one another, but Djinn used her magic to keep Starfire from coming in close enough to deliver a fatal blow.
Meanwhile, the Keeper elected to betray Lady Djinn and used the power at its disposal to teleport Starfire and her allies away from the citadel. It then turned its attention on Lady Djinn. Using a form of molecular alteration, the Keeper transformed her into a living computer terminal. The Keeper activated a self-destruct program which destroyed itself, the citadel and Lady Djinn.
