 The last Guardian fled to an alternate dimension, and began work on a third force to replace the Manhunters.Hundreds of years later, pseudo-Lantern Hal Jordan rediscovered the lost Central Power Battery on Oa, now a mining planet at the heart of the Manhunter's empire.The Guardian contacted Jordan through the Battery and, after telling a slightly distorted version of the history of the Guardians, Corps and Manhunters, instructed him to summon the last remaining ringbearers to Oa and create a feedback loop between their power rings and the Battery, thereby destroying the Lanterns and the Manhunters, allowing the Guardian to return with all threats to his power removed.
