In 3302, a video transmission of an unknown site was intercepted, which showed evidence of ancient non-human ruins. Using the stars visible in the video's background to guide him, Commander Basch Fon Ronseburg (also known as XDeath) was able to locate the site on Synuefe XR-H d11-102 1 b and became the first known person to discover the ancient ruins of the Guardians: an advanced space-faring species that has been extinct for over a million years.

There is a tourist beacon overlooking the site that commemorates his achievement.

After this first discovery, many more Guardian Ruins have been found. Professor Melville posited in the derelict megaship Cete's logs that this system represented "some kind of end point or ‘last colony'". As it turned out, he was right: the first Guardian ruin that humans have discovered was also the last site that the Guardians built, before they were driven to extinction by their own AI.

While hundreds of such ruins have been found over the years, they are all built in three different layouts only. (These are not to be confused with the Guardian Structures though.) These were dubbed Alpha, Beta, and Gamma site, and this site is of the Beta variety.

The site contains a number of active machines called Obelisks that can be scanned, as well as Guardian Relics that can be retrieved from towers that rise from the ground. Numerous small items can be found scattered around the site.

Additionally, bodies 5 b, 5 c, and 5 d all have thin carbon dioxide atmospheres and contain biological samples with a value exceeding 18 million credits per body.
