"We've lived in a state of perpetual war, surrounded by enemies. We were born fighting."

— Talitha Macer on Sedrans

Sedra, also known as Orrichon III, 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. As of 2556, the planet's population was reported as 92% human. Signage in Sedra City was written in both UEG English and Sangheili, indicating facilities were intended for use by both humans and ex-Covenant.

Overview

Topography and ecology

The area around Sedra City features lush vegetation, mountainous forests, and abundant running water. It had cultivated parks, gardens, and ornamental plants used as part of its landscaping. Some of the areas outside the city were linked to the urban center by systems of underground waterways and access tunnels. The planet was home to many species of fern, grasses, low-growing shrubs, flowering plants, terrestrial mosses, and lichens. Its native trees included species that were visually identical to Earth species of ash, beech, birch, oak, spruce, larch, willow, maple, cedars, yew, and Douglas fir. Other notable plants included Rhododendron, elderberry, blackberry, and dandelions. Sedrans were likely involved in some form of forest management, as timber markings could be seen on some of its trees. Sedra is home to a type of plant called the "Sedran red fruit", which was an ingredient in the Have S'Moa "Ground Pounder" burger.

Morning Lake, located just outside of Sedra City, is home to imported white sturgeon and mourning warblers from Earth. Small flying insects could be seen around its waterways, which were preyed on by fish which fed by jumping out of the water to catch them.

History

Human-Covenant war

During the Human-Covenant War, Sedra experienced economic turmoil, which led to an unemployment rate increase throughout the planet. Unlike many Outer Colonies, Sedra survived the Human-Covenant War unscathed. By the end of the war, Sedra held economic stability. Believing that the Unified Earth Government and the UNSC had abandoned them and other Outer Colonies during the war, Sedra sought to become more independent and by 2556, the colony was largely autonomous. The Sedran colonial government attempted to increase the strength of their military branch—the Sedran Colonial Guard—to further eliminate the planet's reliance on the UNSC.

Post-war

On January 24, 2556, border security at Checkpoint Rhoen was forced to enact eight seizures on incoming ships. One of these raids yielded highly refined fissile material. The pilot was arrested and the material was brought to a Sedran laboratory for testing. In response to the influx of passing attempts at the planetary borders, Laban Neir of Rhoen Border Security requested an increase in equipment and personnel. At some point, the UNSC was notified of the fissile discovery. On February 3, 2556, Checkpoint Rhoen was given management of planetary access in sectors four, five, and seven after two Office of Naval Intelligence D79H Pelicans were sent to Sedra. The Pelicans carried an ONI unit led by Jameson Locke, with orders to investigate the discovery of fissile material and prevent any possible terrorist attacks. The team refused formal screening, claiming executive autonomy, and demanded to view the colony's sensor manifest. Upon arrival, the ONI unit also asked for twenty-five percent of Colonial Guard assets to aid them in th
