Void port and neutral ground
A scrapyard station welded together from the wrecks of every expedition that tried to take the fortress by force. Humans and xenos both live on it because it is the only place within reach that neither side can afford to burn.
Position
Map frame: 95, 640 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 429 units ≈ 45.6k light years, south-west of the galactic core.
Height above the disk plane: -11.1 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.
Every fact in this record, and where it came from. Editorial derivations say so.

wh40k.lexicanum.com/wiki/Precipice 'a space station in Segmentum Pacificus that has been cobbled together from the wreckage of numerous ships that have tried to forcibly claim a nearby Blackstone Fortress'
typehigh
station: the source calls it a space station outright, and every book stages from it
gposlow
derived: Segmentum Pacificus, no sector published. Placed near the Pacificus rim because the books repeatedly describe the site as being on the edge of the galaxy, far from Imperial oversight
archetypehigh
catalogue entry 5, fragment-built refuge station — the reference tag is this station by name, and the brief's 'improvised deep-space habitat' is the wreck-welded description quoted above
