Thedus (Earth-5875)

Thedus was a human Outer Colony with numerous facilities to mine rich and natural resources.

History
Founded in 2299, Thedus was immediately proven to be an invaluable planet to claim resources for the Inner Colonies, with companies such as the Weyland-Yutani Corporation mining it extensively during the 2320s. The planet had a population of 700 million.

In 2528, the Weyland-Yutani freighter Nostromo returned from a mission at Thedus when they discovered a mysterious signal at the moon Acheron.

Thedus was glassed and lost to the Covenant in 2543, during the First Contact War, with most of its population dying.
