Moon Base

Continued excavations of the ruins on … have revealed that the abandoned base was once a massive military installation built by the "Armistice Initiative." They were a semi-permanent alliance of at least five large and very advanced interstellar powers active in this galactic region some 75,000 years ago.

The exact nature of this alliance is unknown, but it appears to have been committed to bringing an immediate end to several long-running galactic wars. Large military contingents from each Initiative member were stationed at the base on this moon.

The shielded planet in this system was the capital of one of the warring empires the Armistice Initiative was formed to stop. This empire's name is still unknown - they are referred to simply as "Belligerent Party C" in all Initiative records recovered so far.

Apparently, the Armistice Initiative sought to make an example of Belligerent Party C. After invading their space and winning several hard-fought battles, the Initiative permanently imprisoned the homeworld of Party C behind an energy shield. A military base was established on the nearby moon to maintain the shield and act as a response force in the unlikely event of containment failure.

The Initiative moon base was kept operational for several centuries, but with no signs of containment failure the forces were gradually scaled back. Shifting alliances and infighting between the various Initiative members eventually left the base completely deserted.

Automated systems were left in place to maintain the shield surrounding Party C's homeworld, and they have, incredibly, remained functional up until now. Alas, a critical power cable was severed when our archaeologists dug their way into the subterranean generator chamber. After 75,000 years of continuous operation, the shield is no more.
