The 41st Millenniumpre-Rift
imperium
Cardinal world
A very rich shrine world, thick with pilgrims and Ecclesiarchy money, and a warp-route junction for everything moving through this part of the Segmentum.

Position
Map frame: 230, 570 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 279 units ≈ 29.7k light years, west of the galactic core.
Height above the disk plane: -0.1 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.
System: Gathalamor System
