imperium

[RECORD LOST]
No record for this location in Era Indomitus.
Contested record
Ultima in the wiki infobox; Pacificus in its category. Primary codex verification is still needed.
Position
Map frame: 235.5, 852.2 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 440 units ≈ 46.9k light years, south-west of the galactic core.
Height above the disk plane: 9.4 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.
System: Orestes System

Every fact in this record, and where it came from. Editorial derivations say so.
identityhigh
wh40k.lexicanum.com/wiki/Orestes explicitly the forge/knight world, not Orestes (Sergeant); Titanicus is its primary story setting in the official Warhammer Community reprint descriptions.
wh40k.lexicanum.com/wiki/Orestes Unresolved. infobox says Ultima Segmentum and attributes Codex Imperial Knights (8th Edition),p13; its category says Segmentum Pacificus. The codex page was not directly inspected. Neither claim is silently preferred; segmentum:null denotes this conflict, not proof that no source names a region.
gposlow
inferred: conflicting segmentum claims above remain unresolved. The deterministic unsurveyed-rim marker rim_xy(orestes) carries no positional information and claims neither Ultima nor Pacificus membership. Z is the compute-z.mjs policy value.

editorial: orestes names the survey after its known primary world; the Orestes infobox leaves System blank. This is a rendering identity, not a sourced system name. See the explicitly truncated one-world survey.
