Sedra

Sedra is a distant human Outer Colony planet, located in the Orrichon system. A majority of the planet's colonists hold disdain for the Unified Earth Government.

History
In the post-Covenant War era, an Office of Naval Intelligence unit led by Jameson Locke traveled to Sedra to investigate terrorist activity. However, while on the planet, the unit was caught in a horrific terrorist attack. The ONI unit was forced to work together with a Sedran Colonial Guard commander, Randall Aiken, to stop the terrorists. The origin of the bioweapon was soon tracked down to a shard of Installation 04 that attempted to escape the ring's destruction at the hands of John-117 years prior.

Government and society
Sedra is a relatively poor colony, with most of its industries based on agriculture and industrial manufacturing. The colony has little political significance within the Unified Earth Government. During the Human-Covenant War, the citizens of Sedra felt abandoned by the United Nations Space Command. Although Sedran colonists held resentment towards the UNSC, they still continued to heavily rely on them. The colony is protected by the Sedran Colonial Guard, led by Colonel Randall Aiken. Humans comprise 92% of the planet's total population.

Trivia
In keeping with several mythological references in the Halo universe, the colony of Sedra seems to have Norse influences. While belittling the people of Sedra as "200 years behind [the UNSC]," one of Locke's team members makes mention that the Sedrans "still believe in Valhalla." Valhalla, in Norse mythology, is the High Hall of the god Odin, and one of several afterlife destinations in the Norse belief. Valhalla is also the name of a multiplayer map in Halo 3.
