Jungle death world; Ork incursion
An Imperial world settled for several generations and only recently reclassified as a death world, its jungle of venomous plants and predators growing more lethal by the year. In Death World an Ork incursion has the Imperial Guard garrison calling for reinforcements, and a squad of Catachan Jungle Fighters is sent into the jungle after the Warboss.

wh40k.lexicanum.com/wiki/Rogar_III (read directly in a browser on 2026-10-01): 'Rogar III is an Imperial Jungle Death World', Affiliation Contested (Imperium/Orks), Class Death World, Jungle World, sole source Death World (Novel). https://wh40k.lexicanum.com/wiki/Death_World_(Novel) (read directly in a browser on 2026-10-01): Black Library's description, 'a squad is sent to the death world of Rogar III in response to an ork incursion'; plot summary, 'Rogar III has been settled for several generations, but was only recently classified as a Death World'. Also named in Warhammer Community's Sunday Preview of 19 Apr 2026 (kvkfu6pq) and Saturday pre-orders of 25 Apr 2026 (8qvxr2ay). NAME-COLLISION CHECK: Lexicanum's search for 'Rogar' returns only this page; no other index record uses the name.
classhigh
'death' (this dataset's green-jungle palette) from what the sources say it LOOKS like: Lexicanum's 'Jungle Death World', and the plot summary's jungle of 'semi-sentient poisonous plants', insects, 'jumping lizards' and birds. Here the infobox tag (Death World, Jungle World) and the description agree, which is not always so (see ADDING-A-BOOK Step 5a2). The volcanic eruption in the caverns at the climax is a late, local event and was refused as the world's look.
segmentumhigh
null: Lexicanum Rogar_III leaves Segmentum, Sector, Subsector and System blank and files the page under 'Segmentum Unknown' (read 2026-10-01). No other permitted source places it.
gposlow
inferred: no published segmentum, sector, subsector or bearing. No segmentum is claimed; unsurveyed rim, no positional information. [211.5, 165.0] is build_locations.py rim_xy('rogar-iii') (the function's arithmetic reproduced and checked against jumael-iv's [205.2, 822.6], the script not run); Z 7.1 from compute-z.mjs under zPolicy.
erasmedium
Only 'm41' is carried: Death World (December 2006) is undated in every permitted source and the shelf files it M41 — Pre-Great Rift with the rest of the classic Imperial Guard run. 'contested' from Lexicanum's Affiliation (Imperium/Orks).
systemIdmedium
'rogar' from the world's designation (Rogar III, a third body of a Rogar system); Lexicanum's System field is blank. systems/rogar.json is authored because this is the novel's PRIMARY setting: the third planet and two unnamed inner worlds implied by the numbering, list TRUNCATED.
