Outer Colonies

The Outer Colonies are the most recent Human-colonized planets. Until the Human-Covenant War, disorder and rebellion reigned supreme and chaos. The majority of the Outer Colonies were glassed by the Covenant during the war.

History
Many of the Outer Colonies contained dangerous atmospheres, and some, such as Eridanus II had to have their environments controlled through artificial means.

During the Human-Covenant War, many Outer Colonies were glassed. Beginning in 2525, Harvest was the first world to fall to the Covenant's genocidal wrath. By 2535, with the destruction of Jericho VII, most Outer Colonies had been lost. By 2552, though some Outer Colonies still remained in UNSC hands, most were small and rather insignificant worlds. The significant colonies still under UNSC control lived in constant fear of Covenant invasion.
