Sorry for the bad scale.
In the back there’s the New Eden Cluster.
For orientation: Poitot is to the left of the center, HED-GP below the center.
Assuming New Eden lies relatively flat on a plane and we’re looking at it from Top/Down, then just “above” and in the “south east corner” in the distance there are Jspace and Abyssal DeadSpace, which are relatively close together but clearly distant from New Eden.
The region PR-01 lies somewhere in the “top right corder” far away from the Cluster.
I hope that makes sense. 
In the top picture you see New Eden as you’re used to from the map. Roughtly. My scale’s off, but it’s actually better that way. In the second picture the camera’s zoomed faaar out, and the tiny dot in the top right …
… that’s PR-01.
I know it’s just fluff and does not offer any actually relevant information, but assuming i get this right, then PR-01 is a several millions (?) of light years away from the cluster, just like Jspace and ADspace, though they’re closer. For some reason, unlike the other two, PR-01 lies on the same plane as the cluster does, while the other two don’t. They’re “higher up”.
