imperium
Hive world; capital of the Bethesda Subsector
The capital world of its subsector, orbited by the Exchequer tradestation and the ancient grand cruiser Stang Draak, permanently docked there as its garrison ship. An Ordo Hereticus inquisitor and the Battle Sisters of the Order of the Immaculate Flame sweep its system for a cult behind a wave of spree killings, and an Ork invasion is coming: the setting of Redemption Corps. What the invasion leaves of the world is in the book's spoiler.

wh40k.lexicanum.com/wiki/Spetzghast (read directly in a browser on 2026-10-02): 'an Imperium world', orbited by the Echequer tradestation and the garrison-ship Stang Draak, an Imperial Hive World that served as the capital world of its subsector; infobox Subsector 'Bethesda Subsector', Class 'Former Hive World', every statement cited to Redemption Corps (Novel), chs 2, 3 (pg. 67) and 7. Corroborated by Aurek_Herrenvolk, Diamanta_Santhonax, Order_of_the_Immaculate_Flame and 123rd_Pontifical_Strikes (the cult investigation 'within the Spetzghast System', ch. 2 s. 1-2) and Stang_Draak and Dread_Sovereign (the 'capital world of Spetzghast'). Lexicanum's ship pages spell the system 'Spetzghasf'; the world page and the character pages say Spetzghast, which is the label used. NAME-COLLISION CHECK: no other index record uses the name, and Lexicanum's full-text search returns only this world.
segmentumhigh
null: Lexicanum Spetzghast's infobox has Segmentum and Sector empty (only the Bethesda Subsector, which has no Lexicanum article) and the page is filed 'Segmentum Unknown'.
classmedium
'hive' for what the world IS while the novel is set there: an Imperial Hive World and its subsector's capital (Lexicanum Spetzghast). The infobox's 'Former Hive World' is the novel's ending, not its look, and is kept to the spoiler. No terrain or colour word exists beyond 'Hive World'.
gposlow
inferred: Lexicanum names only a subsector (Bethesda) with no sector, segmentum, neighbour or bearing, so the record claims no segmentum and sits on the unsurveyed rim at the generator's rim_xy('spetzghast') = [231.9, 850.8] (the function ported from build_locations.py reproduces beshic-v [509.7, 56.8] and cressida [791.0, 827.6]; the script itself was not run). The position carries no information and must not be read as one. Z 9.3 is the zPolicy value (compute-z.mjs spetzghast 231.9 850.8).
erasmedium
indomitus only: Lexicanum dates the cult investigation to M42 (Aurek_Herrenvolk, Brutus_Schenker, 123rd_Pontifical_Strikes, citing ch. 3 s. 3) and its List_of_Media_set_during_the_Era_Indomitus places the novel in the Age of the Dark Imperium (Mortensen's homeworld died in 999.M41 when he was a youth; the story is years later). Allegiance 'imperium' (infobox). The shelf files Redemption Corps M42 — Post-Great Rift.
systemIdmedium
'spetzghast': Lexicanum speaks of the 'Spetzghast System' (character pages) and the 'Spetzghasf system' (ship pages) of which this is the capital world, with no other body named. systems/spetzghast.json is a one-body TRUNCATED survey, authored because this is the novel's PRIMARY setting.
