Forge world
A heavily polluted forge world whose masters live deep underground, closer to the core the higher their rank, while scavengers pick over the ruined surface. Known for heavy armour and home to the Titans of Legio Destructor. Belisarius Cawl recruits one of its Constructor-Artisans for his Attilan Gap project.
Position
Map frame: 772, 648 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 310 units ≈ 32.9k light years, south-east of the galactic core.
Height above the disk plane: -9.7 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.

segmentummedium
wh40k.lexicanum.com/wiki/Accatran 'a major Imperial Forge World of the Adeptus Mechanicus located in the Ultima Segmentum', 'Situated on the edge of the Ork Empire of Charadon' (read through a search-engine extract of the page on 2026-09-30 (a direct browser read was not available that run, and Lexicanum refuses WebFetch/curl); needs a direct read to confirm).
classmedium
wh40k.lexicanum.com/wiki/Accatran heavily polluted, rulers underground, 'a hellscape of a surface' (read through a search-engine extract of the page on 2026-09-30 (a direct browser read was not available that run, and Lexicanum refuses WebFetch/curl); needs a direct read to confirm). `forge` is the palette for an industrial, polluted world; here the tag and the look agree.
gposlow
inferred: segmentum-level. Ultima Segmentum is published and so is 'the edge of the Ork Empire of Charadon', but the index holds no Charadon record to place against, so the marker sits in open Ultima space south of the Rift, clear of existing records. The position means only 'somewhere in Ultima'. Z from compute-z.mjs.
erashigh
Only `indomitus` is carried because that is the only era a tracked book names it in; the world is older (Lexicanum: settled in the Dark Age of Technology) and a later book may add earlier eras.
