The 41st Millenniumpre-Rift
imperium
Industrial World of twenty-three hive cities and planet-wide manufactoria
A heavily industrialised world, its surface smothered by vast factorums and hugely overpopulated hive cities, to all intents one planet-sized manufactorum. Its poverty-stricken people work the mines, and it ships shells, tank armour, aircraft glacis, plastek, fuel and chain-weapon teeth to every corner of the Imperium, guarded by a standing army of bastions, blockhouses and patrolling gun-cutters. In the underhive of Molior lie the settlement of Kabullah, the impact chasm called the Well, and the gladiatorial Seven Points Arena. Around 980.M41 a small party of Salamanders comes here in search of an errant fire-born.

Map frame: 358.6, 82 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 441 units ≈ 47k light years, north of the galactic core.
Height above the disk plane: 7.8 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.

settinghigh
wh40k.lexicanum.com/wiki/Sturndrang Lexicanum (read directly in a browser, 2026-10-05), citing only Rebirth (Novel) chs. 4, 9, 19, 23; Lexicanum Zartath ('He accompanied Agatone and Exor to the world of Sturndrang in search of Tsu'gan', Rebirth ch. 3), Exor, Xarko, Clovius ('the hunt for Tsu'gan on the world of Strumdrang') and Forge Hammer ('sent to the Hive World of Sturndrang'). Black Library's blurb (Wayback, https://web.archive.org/web/20141009230015/http://www.blacklibrary.com:80/all-products/rebirth-ebook.html) gives the thread without the world: 'a small party have ventured out in search of a certain errant fire-born'. NAME-COLLISION CHECK: no index record uses the id or label; Lexicanum has one Sturndrang article ('Strumdrang' on the Clovius page is a misspelling).
typehigh
'planet': 'Sturndrang is an Industrial World' (Lexicanum Sturndrang); 'the Hive World of Sturndrang' (Lexicanum Forge Hammer).
classmedium
'hive', chosen from the description words, NOT the 'Industrial World' infobox tag: 'Sturndrang's surface is smothered by a blanket of vast factorums and hugely overpopulated hive cities', 'its 23 hives', 'to all intents and purposes one planet-sized manufactorum' (Lexicanum Sturndrang, ch. 4). The hive palette is this dataset's grey-brown built sprawl with city light on the night side, which is what that describes. 'forge' was refused: in this dataset it paints a soot crust cracked by magma (Nocturne), and no volcanism is described here.
segmentumhigh
null, stated rather than guessed: Lexicanum's infobox gives Segmentum, Sector, Subsector and System as 'Unknown', and no other page read gives a bearing.
gposlow
inferred: named in the novel (Lexicanum Sturndrang and five character and vessel pages) and unplaced anywhere, with no segmentum, sector, subsector, bearing or theatre published. Unsurveyed rim (rim_xy('sturndrang') = [358.6, 82.0], r = 441.3 of the 470-unit disk, outside every stylised segmentum polygon; the function evaluated on its own, reproducing gabal, hive-prome and shau-har exactly; build_locations.py not run), no positional information. Z 7.8 is the zPolicy value (compute-z.mjs sturndrang 358.6 82).
systemIdlow
'sturndrang', named for the world because no system is published. no-system-survey: Lexicanum lists System as 'Unknown' and no page read names a star or another body, so no systems/sturndrang.json is authored.
erasmedium
m41 only, dated with the novel: Rebirth is set five years after the war on Nocturne (Black Library blurb), 980.M41 (Lexicanum Heletine). Allegiance 'imperium': an Imperial manufactory world under its own standing army (Lexicanum Sturndrang); the Chaos ritual shrine found under the Seven Points Arena (ch. 19) is kept off the record as a plot point.
