This archive tracks four layers. A record present in 4 of them (HH, AoI, M41, IND) is silent in the rest, and says so.
The Horus HeresyM30–M31
imperium
Homeworld of Lorgar and the XVII Legion
A world of faith long before the Imperium found it, and the seat of the Covenant that raised Lorgar. Elements loyal to Kor Phaeron seized it in 008.M31 and purged it in the Word Bearers' name.
Age of the ImperiumM32–M40
none
Destroyed
Bombarded from orbit after the Heresy; its own geology did the rest and the planet came apart. Its location is an Inquisition secret.
The 41st Millenniumpre-Rift
none
Destroyed
There is nothing left to visit, and officially nothing to look for.
Era Indomituspost-Rift
none
Destroyed
Unchanged, and the Inquisition would prefer it stayed that way. The world that taught Lorgar to believe is still in pieces at a coordinate nobody is supposed to have.
Position
Map frame: 118, 660 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 414 units ≈ 44.1k light years, south-west of the galactic core.
Height above the disk plane: -4.5 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.
System: Colchis System

wh40k.lexicanum.com/wiki/Colchis infobox Class = 'Dead World, Destroyed 035.M31', which is the world's state AFTER this record's aoi entry, not its baseline. The destruction is carried by the aoi and m41 statuses instead. For the living world the class is editorial: no source we hold states a terrain type, and the published descriptions are of an arid world of ancient temple-cities, so it is rendered desert. Low confidence and flagged as our reading, not a transcribed value
gposlow
wh40k.lexicanum.com/wiki/Colchis derived: Segmentum Pacificus, south-west of Hydraphur. Note the canon irony — states the planet's location is a secret guarded by the Inquisition, so any placement is editorial by definition
era-indomitushigh
this entry exists to close a rendering gap, not because a new source appeared. app/src/stages/system.js draws a planet in every era whether or not its record carries that era, and derives a destroyed world's grey from eras[era].status — so an era key the record does not carry falls back to the survey class and the world comes back to life in it. With the baseline moved to this world's LIVING appearance, a missing indomitus key would have done exactly that. The status carries forward what the preceding era already states, on the same source; nothing new is claimed
