wh40k.lexicanum.com/wiki/Járnhamar_Pack (read 2026-10-12 with fetch-page.mjs, section 'The Stormcaller', citing Stormcaller (Novel), Chapters 6-12): 'the Wolves aboard the asteroid station confirm the Festerax is heading towards the Hive World of Kefa Primaris … Olgeir is dispatched ahead in the System Runner Hlaupnir to warn the Planetary Governor … Olgeir arrives at Kefa Primaris and warns the Governor of the impending threat'. Also https://wh40k.lexicanum.com/wiki/Ingvar_Orm_Eversson (Chapters 18-19: 'the nearby Hive World of Kefa Primaris') and Mycelite (Chapter 14: 'culminating at the Hive World of Kefa Primaris'). https://wh40k.lexicanum.com/wiki/Kefa_Primaris has no text (read 2026-10-12). A planet. NAME-COLLISION CHECK: no index record uses the id or label.
book-joinmedium
VISITED for Stormcaller: Olgeir's run to warn the Governor (Chapters 11-12, Lexicanum Járnhamar_Pack); the hulk's goal throughout the second half.
segmentumhigh
null, stated rather than guessed: no permitted page gives a segmentum, sector or system for Kefa Primaris.
classlow
'hive', from the only description any permitted page gives: 'the Hive World of Kefa Primaris' (three Lexicanum articles). No terrain or colour words are published, so the palette follows the hive designation itself rather than an invented look.
gposlow
inferred: no position is published. Placed 16 units from ras-shakeh on the unsurveyed rim because Lexicanum Ingvar_Orm_Eversson calls it 'the nearby Hive World' (Stormcaller, Chapters 18-19); ras-shakeh's own position is an unsurveyed-rim point (rim_xy) that carries no information, so this one carries only that relation. Not rim_xy('kefa-primaris'), which would put a world called nearby on the far side of the galaxy. Z 9.3 is the zPolicy value (compute-z.mjs kefa-primaris 408.2 67.6).
erasmedium
m41 only, with the novel. Allegiance 'imperium'. Its fate is not stated on a permitted page.
systemIdlow
'kefa-primaris', named for the world because no system is published.
