Eirene was a human colony world.
The Covenant found Eirene at some point. This lead to Kelly-087 being deployed on the planet in Operation: PALE SHADOW. Here, she entered a Covenant forward operating base and caused a leak in the base's reactor, resulting in a 50 megaton explosion going off. She single-handedly saved the city of New Kona for an unknown amount of time. However, the planet was still glassed by the Covenant some time before 2537.[note 1]
- ↑ To have been in the field during the Human-Covenant War, Jonah must have been a graduate of either Alpha or Beta company, as Gamma was still in training by late 2552. Beta Company was initiated in 2537, meaning the planet was glassed some time before it.
