Glacia

Glacia was a New Covenant colony within the Eros System. The planet consists of large frozen oceans, large islands covered in ice and snow. The moon of Glacia known as Di'aira, is close enough to the planet to make tides shift at a dangerous level for four hours out of the day. The atmospheric conditions are stable enough for humans, and Unggoy to breath without major , (though the latter must have at least one hour of methane breathing treatments, which usually means the Unggoy wear their body armors outside of their living quarters).Glacia was the first colony to actually harbor both Humans, Sangheili, and Unggoy. Of course the population is unbalanced due to the fact Unggoy breed extremely fast.
