The Redoubt

The Redoubt was a Kig-yar keep. It was found on the moon Metisette, in the 23 Librae system, and was made out of parts of old ruined ships, and could house hundreds of thousands of Unggoy. It was built by Reth, and has a large river of liquid Methane that runs into a large crater. There were giant reactors around the crater, which heated it and turned the liquid into gas, making thick mist which were perfect conditions for Unggoy to live in. It also served as a breeding ground for the Unggoy and was also surrounded by several Covenant buildings.

During the Battle of Metisette, ODST's and two SPARTAN's from Gray Team landed in the Plaza via SOEIV's, not far from the river of liquid methane. They destroyed all the Anti-Aircraft guns in the plaza, then planted a SHIVA Nuclear Warhead in the sensor control building, before being picked up by Pelican Dropship's and taken to UNSC Midsummer Night. The nuclear blast destroyed the sensor building allowing The Redoubt to be destroyed by several of The Rubble's asteroid habitats. Reth, the leader of the Kig-yar forces, was killed by one of the asteroids, when it collided with the ship he was attempting to escape in.
