Forge world of the Adeptus Mechanicus
A forge world of the Adeptus Mechanicus and sibling to the lost forge world Velchanos Magna. The STC that Magos Explorator Omnid Torquora recovers is brought here, and its Fabricator Locum, Engra Myrmidex, flies the Ark Mechanicus Opus Machina. What the STC does to it is kept off this record because it would spoil the book.

No record for this location in Era Indomitus.
Position
Map frame: 92, 325.6 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 444 units ≈ 47.2k light years, north-west of the galactic core.
Height above the disk plane: -2.8 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.

identityhigh
wh40k.lexicanum.com/wiki/Adeptus_Mechanicus:_Skitarius_(Novel ) (read directly in a browser on 2026-10-01): the STC 'is found and returned to the forge world Satzica Secundus'. https://wh40k.lexicanum.com/wiki/Omnid_Torquora (read directly in a browser on 2026-10-01): 'After returning the STC to the forge world Satzica Secundus', citing the novel. https://wh40k.lexicanum.com/wiki/Ark_Mechanicus (read directly in a browser on 2026-10-01): 'Opus Machina — Flagship of Fabricator Locum Engra Myrmidex of Satzica Secundus', citing the novel's 0011, and 'Encoronada — From the Forge World Satzica Secundus', citing Tech-Priest. NAME-COLLISION CHECK: https://wh40k.lexicanum.com/wiki/Satzica_Secundus has no article (read 2026-10-01), and no other index record uses the name.
classmedium
'forge': every source calls it a forge world (Lexicanum novel page, Omnid_Torquora, Ark_Mechanicus) and none describes its surface otherwise. No infobox exists to compare.
segmentumhigh
wh40k.lexicanum.com/wiki/Adeptus_Mechanicus:_Skitarius_(Novel null: no permitted source gives Satzica Secundus a segmentum, sector, subsector or system. Read 2026-10-01: ), https://wh40k.lexicanum.com/wiki/Omnid_Torquora, https://wh40k.lexicanum.com/wiki/Ark_Mechanicus, https://wh40k.lexicanum.com/wiki/Standard_Template_Construct; Lexicanum has no Satzica Secundus article.
gposlow
inferred: no published segmentum, sector, subsector or system, and nothing places it against a neighbour except as Velchanos Magna's 'sibling' (Lexicanum Omnid_Torquora), which gives no distance, so the two are not drawn together. No segmentum is claimed; unsurveyed rim, no positional information. [92.0, 325.6] is build_locations.py rim_xy('satzica-secundus'); Z from compute-z.mjs under zPolicy.
erasmedium
Only 'm41' is carried, on the same reasoning as Velchanos Magna (released April 2015, shelf filing M41 — Pre-Great Rift, no published date). Allegiance 'imperium' at the book's opening. The world's fate in the novel (Lexicanum Omnid_Torquora) is a spoiler and is kept off the record.
systemIdlow
editorial: 'satzica-secundus', the world's own name; no permitted source names its system or star, or a Satzica Primus. No survey is authored: it is a visited setting, and the synthesiser draws it from this record's class.
