This archive tracks four layers. A record present in 2 of them (HH, IND) is silent in the rest, and says so.
The Horus HeresyM30–M31
imperium
Imperial world, its verdant soil guarded by great orbital defence platforms
Settled by humans millennia before, in the golden age of antiquity, by colonists who outlasted the ancient xenos civilisations they fought. In the time of the Great Crusade and the Horus Heresy great orbital defence platforms were raised over its then-verdant soil, and they held for thousands of years.

ork
Ork-conquered world in nuclear winter; the camp of Waaagh! Big Zag
Once an Imperial world of several billion people, now held by Waaagh! Big Zag. His ships dropped out of the Warp mere miles above the surface, inside the orbital defences, and turned them on the Imperial fleet. The last stand of an Astra Militarum force and a Mentors Astartes in Hive Septimus ended when the kill kroozer Da Original Biggun crash-landed on the hive. No human was left alive. In the nuclear winter that followed, Big Zag rules from a captured Capitol Imperialis over a Blood Axe encampment and its walled Mektown, where the painboy Stimma finds the grots behaving far too well.

wh40k.lexicanum.com/wiki/Karanos_V (read in a browser, 2026-10-05), citing Da Gobbo Rides Again: 'a former Imperial world, overrun by Orks' in the Karanos System; settled in the golden age of antiquity; orbital defence platforms of the Great Crusade and Horus Heresy bypassed by Waaagh! Big Zag; the Astra Militarum and Mentors last stand in Hive Septimus crushed by the kill kroozer Da Original Biggun; several billion killed (Prologue); Big Zag's Capitol Imperialis in the nuclear winter (Chapter 2); Mektown (Chapter 3); 'the site of a Revolushun sparked by an incarnation of Da Red Gobbo' (Chapter 4). Corroborated by Lexicanum Stimma, Big_Zag and 'Say_Yes'_Yag; Black Library's description (via Lexicanum Da_Gobbo_Rides_Again_(Novella)) gives 'the bitter cold of a nuclear winter' and 'a Blood Axe encampment'. NAME-COLLISION CHECK: no index record uses the id or label, and Lexicanum has one Karanos V.
classlow
Painted `ice` because the only surface any permitted source gives for the book's era is 'the bitter cold of a nuclear winter' (Black Library description) that followed the conquest (Lexicanum Karanos_V, Big_Zag, Chapter 2): a frozen, ash-dimmed world. Lexicanum's infobox leaves Class blank, so there was no tag to copy. `dead` was refused because the world still holds a whole Ork Waaagh! and its grots. `temperate` belongs to the HH era only, from 'then-verdant soil' (Lexicanum Karanos_V, Prologue), and is authored as eras.hh.class. This is a reasoned look, not a published one.
segmentumhigh
wh40k.lexicanum.com/wiki/Karanos_V null, stated rather than guessed: leaves Segmentum, Sector and Subsector blank and files the page under 'Segmentum Unknown'. No Warhammer Community article (22 Oct 2023 Sunday Preview, 28 Oct 2023 Black Library pre-orders, 3 Nov 2023 Da Red Gobbo's Surprise) names the world or a region.
gposlow
inferred: named in the book, unplaced everywhere else, with no segmentum, sector, subsector, bearing or theatre published. Unsurveyed rim (rim_xy('karanos-v'), r = 437.1 of the 470-unit disk, outside every stylised segmentum polygon), no positional information. Z 5.1 is the zPolicy value (compute-z.mjs karanos-v 840.1 225.5).
systemIdhigh
'karanos', the Karanos System of Lexicanum's Karanos_V infobox (System: Karanos System). Surveyed in systems/karanos.json as one world, TRUNCATED: the numeral implies four inner bodies that no permitted source names.
eraslow
hh from Lexicanum Karanos_V (Prologue): settled in antiquity, orbital defence platforms set up 'During the time of the Great Crusade and Horus Heresy' over 'then-verdant soil'; allegiance imperium. indomitus is INFERRED with the run: no permitted page dates the conquest, and Lexicanum's List_of_Media_set_during_the_Era_Indomitus does not list the novella (read 2026-10-05; it lists Da Gobbo's Revenge). It is filed beside Da Gobbo's Revenge and Da Gobbo's Demise in M42. Allegiance ork: no human was left alive (Prologue), though fighting was 'not yet over' (Lexicanum Big_Zag, Chapter 6). m41 and aoi are left unauthored because no source says when the Waaagh! arrived. NEEDS CHECKING against the novella.
