imperium
Civilised world; Ibram Gaunt's homeworld
The world Ibram Gaunt grew up on, in the Khulan Sector: the family house stood on Mount Resyde, looking out over waterfalls falling into the Northern Rift and, on clear days, the vast Lanatre Fields spaceport. He left it as a boy, and it survives in his memory rather than in any campaign.

wh40k.lexicanum.com/wiki/Manzipor (read directly in a browser on 2026-10-03): 'a Civilised World of the Imperium, notable for being the homeworld of Ibram Gaunt'; the Gaunt family home on Mount Resyde, the waterfalls into the Northern Rift, the Lanatre Fields spaceport (citing First and Only, 'A Memory: Manzipor, Thirty Years Earlier'); Sector 'Khulan Sector' (citing The Vincula Insurgency, Chapter Seventeen). https://wh40k.lexicanum.com/wiki/List_of_Gaunt%27s_Ghosts_Characters gives Manzipor as Gaunt's home and his earliest chronological appearance. NAME-COLLISION CHECK: no other index record uses the name.
classmedium
'temperate' for what the page says it LOOKS like: a mountain-top house above waterfalls cascading into a rift valley, with a great spaceport in view on clear days (Lexicanum Manzipor). The infobox's 'Civilised World' is a status, not a surface; nothing suggests ice, desert, jungle or hive.
segmentumhigh
wh40k.lexicanum.com/wiki/Khulan_Sector: null: Lexicanum Manzipor's infobox leaves Segmentum, Subsector and System empty and files the article under 'Segmentum Unknown'; its sector, the Khulan Sector, has no Lexicanum article ( 'There is currently no text in this page', 2026-10-03) and no index record.
gposlow
inferred: no permitted source places the Khulan Sector or Manzipor, so the record claims no segmentum and sits on the unsurveyed rim at the generator's rim_xy('manzipor') = [943.3, 550.2]. The position carries no information and must not be read as one; it exists so the world the novel names has a marker. Z 3 is the zPolicy value (compute-z.mjs manzipor 943.3 550.2).
erasmedium
m41 only: Gaunt's boyhood there 'thirty years earlier' than First and Only (Lexicanum Manzipor), and The Vincula Insurgency names it (ch. 17) in M41 — Pre-Great Rift. Mentioned in the novel, not visited.
systemIdlow
'manzipor': no source names its system; no systems/manzipor.json is authored (a mentioned world with nothing enumerated, ADDING-A-BOOK Step 5b 'When NOT to author a survey').
