Nordarus

Nordarus was human colony first settled in 2439, and prior to the activation of the it was likely inhabited by Forerunners. It was  by the in 2533.

The Forerunners
Little is known about the Forerunners' activity on Nordarus, other than that they built at least one structure there.

Human Colonization
The first human settlers arrived on Nordarus aboard the Rōtasupetaru in 2439. These settlers were of predominantly Japanese descent. Events on Nordarus were relatively undocumented for unknown reasons until 2461, when a second colony ship, the Kongen i Nord, which carried Norwegian colonists, arrived on the planet. By then, Nordarus was almost fully terraformed, and the population had increased greatly, with the planet's handful of cities now densely populated.

More settlers of assorted backgrounds arrived over the years aboard freighters and tourist ships, but the population of Nordarus remains primarily of either Japanese or Norwegian descent, or a mix of the two.

Early War
In the beginning of the Human-Covenant War, Nordarus's population remained relatively in the dark regarding the conflict, as the planet was located in an isolated area in the fringes of UNSC space, and was often overlooked. Some, though not a considerably large number of people by any means, but still worth mention, were unaware that any such conflict existed at all.

The Battle of Nordarus
The Nordari people remained fairly ignorant of the Covenant threat until March 2533, when a sizable Covenant naval force launched an assault on the colony, and protocol was enacted. While Nordarus was not of any real importance to the UNSC, the newly established required that some form of military response be undertaken. The 17th Naval Fleet, which was fairly close to Nordarus when the Covenant invasion began as it had been patrolling the Outer Colonies following the in 2531, arrived about 4 weeks after the initial attack, and immediately began to assist the overwhelmed local defense fleet and  forces.

The battle remained a fairly minor engagement until the Covenant Everlasting Profession of Zeal detected a Forerunner installation below the surface of the planet while landing troops for an assault on the city of New Osaka. After making this discovery, the Covenants forces quickly became much more aggressive and determined. The UNSC soon discovered the Forerunner relic as well, and would recruit the assistance of Sapphire Team and Addison Solaski in order to gain access to the installation, retrieve some information from it for study, then destroy it to prevent it from falling into Covenant hands.

Nordarus and approximately three quarters of its population was ultimately lost to the Covenant, who glassed the colony in early May.
