Sedra is an outer colony world in the Orrichon star system. Despite the heavy toll taken on human colonies as a whole throughout the Human-Covenant War, Sedra was among the colonies that were lucky enough to have escaped the conflict virtually unscathed. This has allowed Sedra to remain largely autonomous from the UNSC, though the colonial government has maintained relatively close ties in regards to military hardware acquisition. As a result, the Sedran Colonial Guard has been able to remain relatively well-equipped in efforts to safeguard their colonists.
