This area is notable for housing a large number of Guardian ruins, second only to the original Guardian space itself. The center appears to be the IC 4673 planetary nebula, which used to be accessible to explorers in the early years of exploration, but was locked down by the Pilot's Federation a couple of years later.

Today, systems within 100 ly of the nebula cannot be entered. However, outside of this area, in the Graea Hypue sector, there are several clusters of ancient Guardian ruins, some of them right outside the permit-locked area. The closest one found to date is the Graea Hypue QL-V b19-15 system, which has three planets (C 3, C 4, D 2) where ruins can be found.

While most of the known Guardian sites can be found in the Gamma Velorum not far from human space, explorers have found clusters of ruins around distant nebulae, such as this one. It's unclear whether these remote sites held any sort of unique significance to the aliens: they are only mentioned in passing in what data could be recovered from the Guardian obelisk network.

This area is larger in size than the other distant Guardian clusters, and houses significantly more ruins than them, but it seems to hold no differences otherwise.

The list of currently known Guardian sites can be found in the Catalog of Guardian Structures and Ruins.
