Thedus was a mining world located in the Epsilon Reticuli System approximately 59 light years Trailward from Earth.

History

Initially mistaken for a small gas giant, Thedus was in fact a terrestrial planet loaded with heavy metal veins that were quickly and heavily exploited by the Weyland-Yutani Corporation for more than a century, leaving much of the planet's surface riven with huge gouges and deep canyon–like trenches. Alongside Anchorpoint Station, Thedus was a transit point for exported materials being moved from the Frontier to the Outer Veil and Core Systems.

During the Torin Prime uprising in 2106, J'har advisors fomented a labor dispute on Thedus to disrupt the United Americas' military supply lines to Torin Prime; this dispute lasted four months.

In 2109, Thedus suffered a severe environmental accident that rendered parts of the planet uninhabitable for decades, followed by a miners' revolt over poor living conditions. The incident forced the United Americas to deploy the United Americas Outer Rim Defense troop carrier UAS Archangel on a peacekeeping mission to Thedus. On December 25th, 2109, for unknown, classified reasons, the Archangel crashed into an atmospheric processor, destroying the site and killing 15,293 civilians and marines. The incident vetoed the UAORD expansion initiative and led to its restructuring into the Outer Rim Defense Fleet.

In 2121, Thedus was the last port of call for the commercial towing vehicle USCSS Nostromo before the ship went missing alongside the Tesotek 2100-B refinery it was towing in 2122. As of the 2180s, most of the historic damage effected on Thedus' surface had been repaired via terraforming.

Climate and terrain

Though cold, Thedus' atmosphere was breathable for humans, with a mean temperature of 8°C. Thedus was mainly terrestrial, with the planet containing various heavy metal deposits.

Economy

Thedus' key resources included yttrium, niobium, helium-3, and other rare earth metals.

Population

As of 2183, Thedus' human population stood at 2,000,000.

Points of interest

The United States Colonial Marine Corps Eridani Marine Space Force garrison was stationed on Thedus. The Weyland–Yutani Corporation maintained one of its main offices on Thedus.
