Besieged jungle world of the Gallows Cluster
A war-torn jungle world whose bastions the Imperium must hold while the whole Gallows Cluster buckles under enemy attack. Its jungle is as deadly as any enemy. In Hell's Last the Cadian 101st, Minka Lesk's regiment, are sent to break the siege there.
Position
Map frame: 692.2, 97.5 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 446 units ≈ 47.5k light years, north-east of the galactic core.
Height above the disk plane: -2.6 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.

identityhigh
Named as the novel's setting in Warhammer Community's own posts for Hell's Last, read directly in a browser on 2026-10-02: the reveal (World Championships Preview, gw3wcpc7, 22 Nov 2024: 'defend vital bastions on the war-torn world of Alia'), the Sunday Preview (ndhfp4zl, 16 Feb 2025: 'the deadly jungle world of Alia') and the Saturday Pre-orders (fwhdwwag, 22 Feb 2025: 'the deadly jungle world of Alia'); the same blurb on Lexicanum Hell's_Last_(Novel). Lexicanum has no article for Alia (the page is empty) and its full-text search for 'Alia' returns only the novel page and an unrelated 'inter alia'. NAME-COLLISION CHECK: no other Alia on Lexicanum and no index record uses the name.
book-joinhigh
PRIMARY for Hell's Last (minka-lesk::ml-main::5): every official account sends the Cadian 101st to Alia and sets the push through its jungle and the siege there as the book's action (Warhammer Community gw3wcpc7, fp9d9s5n, ndhfp4zl, fwhdwwag).
classmedium
'death' for what the sources say it LOOKS like and is: 'the deadly jungle world of Alia' (Sunday Preview; Saturday Pre-orders), 'a jungle as deadly as any enemy' (reveal), 'pushing through a deadly jungle' (LVO Preview fp9d9s5n). This dataset's `death` palette is the toxic jungle canopy, which is the description; `feral` (the unspoiled green world) was refused because every source stresses the jungle is lethal. No infobox exists to copy.
segmentumhigh
null: no permitted source names a segmentum, sector or subsector for Alia or the Gallows Cluster. The Sunday Preview says the threat in the Gallows Cluster endangers 'the entire sector', which is unnamed.
regionmedium
In the Gallows Cluster: the Saturday Pre-orders put Lesk's company on Alia 'when darkness rises in the Gallows cluster', the Sunday Preview has the Gallows Cluster threat fall to Lesk 'on the deadly jungle world of Alia', and the reveal pairs the Alia bastions with 'the entire Gallows Cluster buckles under relentless enemy attack'. None says 'Alia is in the Gallows Cluster' in so many words, hence medium. The cluster's capital is Potence (Lexicanum Potence: 'an Imperial Capital World in the Gallows Cluster'), already in this index.
gposlow
inferred: placed WITHIN THE PUBLISHED REGION (SCHEMA.md: 'sector, subsector, cluster'), i.e. beside Potence, the Gallows Cluster's capital and the only located member of the cluster in this index, at a 2.5-unit editorial offset toward the core (Potence [693.3, 95.2] -> [692.2, 97.5], r 446.0, inside the disk). Potence itself sits on the unsurveyed rim because canon gives the cluster no position, so this coordinate says only 'same cluster as Potence' and carries no galactic information of its own. The offset distance and bearing are editorial. Z -2.6 is the zPolicy value (compute-z.mjs alia 692.2 97.5).
erasmedium
indomitus only: the Minka Lesk novels follow the Cadian 101st after the fall of Cadia (reveal: 'the tumultuous times following the fall of Cadia'; Lexicanum Cadia_(Novel_Series)), and the shelf files the run M42 Post-Great Rift. Allegiance 'contested': a war-torn world whose Imperial bastions are under siege (reveal; LVO Preview).
