identityhigh
wh40k.lexicanum.com/wiki/Yulzond_Cross (read directly in a browser on 2026-10-02): 'an Imperium world that is home to war-ravaged cities. It was once invaded by the Tyranid, and among the Imperium's forces that came to its defense were the Battle Sisters of the Order of the Bloody Rose', citing The Bloodied Rose (Novella), Chapter 1; infobox Affiliation Imperium, Segmentum, Sector, Subsector, System and Class Unknown. NAME-COLLISION CHECK: no index record uses the name.
segmentumhigh
null: Lexicanum's infobox gives segmentum, sector, subsector and system as Unknown (category 'Segmentum Unknown').
gposlow
inferred: the world is NAMED but canon never locates it, so the record claims no segmentum and sits on the unsurveyed rim at the generator's rim_xy('yulzond-cross') = [792.3, 179.0] (the function in build_locations.py evaluated on its own, which reproduces regallus and lautis; the script itself was not run). The position carries no information and must not be read as one. Z -11.2 is the zPolicy value (compute-z.mjs yulzond-cross 792.3 179.0).
classlow
'temperate' as a neutral default: the only description is 'home to war-ravaged cities' (Lexicanum Yulzond_Cross), which is not enough for 'hive' (no hive is named) and names no terrain or colour. Lexicanum's Class field reads Unknown.
eraslow
indomitus only, the era of the one book that names it (The Bloodied Rose, filed M42 — Post-Great Rift); the Tyranid invasion is undated and lies somewhere in Augusta's twenty-year career. Allegiance 'imperium' from Lexicanum's infobox; the status avoids words the status-prose rule repaints, because the invasion's end is not recorded.
systemIdlow
editorial: 'yulzond-cross', the world's own name; Lexicanum's System field is Unknown. No survey is authored: the world is only mentioned.
