Overrun by Chaos cultists
The world whose mysterious distress call draws Shield-Captain Cartovandis and a band of Custodians from Terra in the first days of the Great Rift (Auric Gods). They find it in the grip of self-annihilation, overrun by Chaos cultists. Canon says nothing else about it: not its place, its people or what it looks like.
Position
Map frame: 896.8, 713.6 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 451 units ≈ 47.9k light years, south-east of the galactic core.
Height above the disk plane: -5.7 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.

identityhigh
wh40k.lexicanum.com/wiki/Auric_Gods_(Novella ) (read directly in a browser on 2026-10-02), Black Library's description: 'When Shield-Captain Cartovandis receives a mysterious distress call from the planet Vorganthian ... they find a world in the grip of self-annihilation, overrun by Chaos cultists'; https://wh40k.lexicanum.com/wiki/Servants_of_the_Imperium_(Anthology) ('a mysterious distress call from the world of Vorganthian'). Lexicanum has no Vorganthian article (the link is red) and its full-text search finds only those two pages. NAME-COLLISION CHECK: no index record uses the name, and Lexicanum knows no other Vorganthian.
segmentumhigh
null: no permitted source gives a segmentum, sector or system for Vorganthian; Lexicanum has no article for it.
gposlow
inferred: the world is NAMED but canon never locates it, so the record claims no segmentum and sits on the unsurveyed rim at the generator's rim_xy('vorganthian') = [896.8, 713.6] (the function in build_locations.py evaluated on its own, which reproduces regallus [665.1, 898.2] and misbah [374.1, 934.0]; the script itself was not run). The position carries no information and must not be read as one. Z -5.7 is the zPolicy value (compute-z.mjs vorganthian 896.8 713.6).
classlow
'temperate' as a neutral default: the only description is 'a world in the grip of self-annihilation, overrun by Chaos cultists', which says what is happening there, not what it looks like. No terrain, city or climate word exists in any permitted source, so neither hive nor daemon is painted on it, as for misbah and nikaea.
erasmedium
indomitus only, the era of the one book that names it (Auric Gods, filed M42 — Post-Great Rift: its description opens 'when the Great Rift tears the Imperium apart', and Lexicanum's List of Media set during the Era Indomitus lists it). Allegiance 'contested': an Imperial world calling for help while 'overrun by Chaos cultists'; its fate is not recorded, so the status avoids words the status-prose rule repaints.
systemIdlow
editorial: 'vorganthian', the world's own name; no source names its system. The survey systems/vorganthian.json is ONE WORLD and TRUNCATED.
