Betrayal of Krona

Manipulation
While documenting the Multiverse, the guardian Krona makes contact with Mobius, who resides in the Antimatter Universe. Mobius, now calling himself the Anti-Monitor, wishes to destroy the multiverse in order to gain revenge on his former master, the Presence.

The Anti-Monitor manipulates Krona, instructing him to gather the three entities that escaped the White Lantern, following its destruction. Once the entities are gathered, Krona must enter the House of Heroes, the nexus point of the Multiverse, and create a portal to the Antimatter universe, so that Mobius can return.

Krona, fueled by a hunger for knowledge, agrees to help Mobius.

Diversion
Krona succeeds in gathering two of the entities: Ion (Will), and Parallax (Fear). He harnesses their power in a gauntlet which he creates. In order to distract his fellow Guardians, Krona reprograms the Manhunter robots, sending them on a killing spree throughout the universe.

The rampage is known as "The Massacre of Sector 666", where the robots commit genocide across numerous planets, including the planet Ysmault.

Intervention
Though only having two entities, Krona prepares to cross into the House of Heroes, but is stopped by a small group of guardians led by Appa Ali Apsa. A fight ensues, where Krona kills Appa, but his gauntlet is destroyed by the guardian Ganthet, releasing the entities. Ganthet's will allows him to contain the Ion entity, but Parallax escapes. The Manhunters are stopped, but Krona's damage is already disastrous.

On Ysmault, the only survivor of the massacre, Atrocitus, is greeted by the entity of Rage, the Butcher, who fuses with him.

The Guardians use Ion's power to create a Central Power Battery, where they imprison Krona for millennia.
