The 41st Millenniumpre-Rift
imperium
Remote hive world
A long way from anywhere, its plains worked over by scavengers digging up the technology of whoever was here before. A quiet place to grow up, and the entire reason it was worth attacking.
Era Indomituspost-Rift
necron
Destroyed; torn apart by the Necrons
Ketatrix Dynasty ships arrived over it without warning and took the planet to pieces. The survivors left in whatever would fly.
Position
Map frame: 120, 712 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 435 units ≈ 46.3k light years, south-west of the galactic core.
Height above the disk plane: 8.2 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.
System: Targian System

derived: Segmentum Pacificus, no published sector, and described as remote. Placed in the segmentum's southern reach, well clear of the Sabbat Worlds cluster, since nothing published ties it to that region
era-indomitus-statushigh
wh40k.lexicanum.com/wiki/Targian 'The planet was then destroyed by the Necrons'. The status led with 'Torn apart by the Necrons', which is the same claim in words app/src/stages/palettes.js STATUS_CLASS does not match, so the world went on rendering as a live hive world through its own destruction. 'Destroyed' now leads and the manner of it qualifies
era-conflictmedium
wh40k.lexicanum.com/wiki/Targian dates the Necron invasion to 'sometime after the Great Rift's creation', which is Era Indomitus — but the tracker tags Attack of the Necron as M41. Both are honoured: the m41 entry is the intact hive world, the indomitus entry is its destruction, and the book link carries the tracker's era
