imperium
Knight world of House Cadmus
A lush Knight world of evergreen forest so dense that only the plateaus that pierce the canopy are clear. House Cadmus rules it from Golem Keep, and every midsummer its Knights hunt the abhuman tribes of the forests in the Cull, whose winner rules the house for a year.

imperium
Knight world of House Cadmus
House Cadmus still holds Raisa from its fortified keeps on the forest plateaus, now sworn to the Adeptus Terra rather than the Adeptus Mechanicus since the fall of Gryphonne IV.

wh40k.lexicanum.com/wiki/Raisa (read directly in a browser on 2026-10-03): 'a Knight World of the Imperium' (Codex: Imperial Knights 6th Edition, Notable Knight Worlds; 10th Edition pg. 30). https://wh40k.lexicanum.com/wiki/House_Cadmus (read directly in a browser on 2026-10-03): House Cadmus's Knight World is Raisa, and its pre-battle feast tradition is held on Raisa at Golem Keep, cited to Knights of the Imperium chapters Roland and Weaknesses. NAME-COLLISION CHECK: no other index record uses the name.
segmentumhigh
'tempestus': Lexicanum Raisa infobox 'Segmentum: Segmentum Tempestus', citing Codex: Imperial Knights (6th Edition). Sector and system 'Unknown'.
classmedium
'feral' from what the page says it LOOKS like: 'The native flora of this lush world grows with such virility that only the vast plateaus that pierce the evergreen canopy are free from their touch', 'canopies of continent-spanning forested wilderness' (Lexicanum Raisa, Codex 6th and 10th Editions). That is dense green forest under cloud, which is the feral palette (dense jungle greens). 'death' (this dataset's hostile green jungle) was weighed and refused: Raisa is a ruled Knight world whose forests the house hunts for sport, not a world that kills its settlers; the infobox tag 'Knight World' is a political class and says nothing about how it looks.
gposlow
inferred: Segmentum Tempestus is published, the sector and system are not. Codex: Imperial Knights (6th Edition), via Lexicanum House_Cadmus, calls Gryphonne IV 'the nearby forge world', so Raisa is placed a short way from Gryphonne IV's marker [470, 875] in the southern Tempestus interior, at [490, 895]. Region-level only. Z -5.6 from compute-z.mjs under zPolicy.
erashigh
m41: the forests, plateaus, Golem Keep and the Cull (Lexicanum Raisa, Codex 6th Edition; House_Cadmus, Codex 6th Edition). indomitus: the keeps on the forest plateaus (Raisa, Codex 10th Edition pg. 30) and the house's allegiance to the Adeptus Terra (House_Cadmus, Codex 10th Edition pg. 30). No hh or aoi entry: House Cadmus fought in the Great Crusade and at the Siege of Terra, but nothing permitted places Raisa itself in those eras.

No systems/raisa.json: Raisa is a `mentioned` join in the only book that brought it here (Knights of the Imperium), not a primary setting, and canon names no star, sibling or moon. Upgrade candidate the day a book is set there.
