Under the faltering Waaagh! of Beastboss Bakmun
The target of Beastboss Bakmun's Waaagh!, a rampage that is threatening to peter out when Mad Dok Grotsnik arrives with his orderlies and his colossal Painwagon. No permitted source says who holds the hive, what world it stands on, or where it lies.

www.blacklibrary.com/all-products/ebook-grotsnik-da-mad-dok-eng-2025.html Black Library's own description (, Internet Archive capture 20250805045605): 'Grotsnik comes to the aid of Beastboss Bakum on Hive Prome' and 'Beastboss Bakmun, whose rampage on Hive Prome teeters on the brink of going out not with a Waaagh! but with a whimper'. Warhammer Community reveal (12 Feb 2025, https://www.warhammer-community.com/en-gb/articles/xqwu6c0l/da-mad-dok-is-in-grotsnik-puts-on-a-clinic-in-a-new-black-library-book/): 'the beleaguered Bakum, whose faltering Waaagh! against Hive Prome is threatening to peter out'. Lexicanum Bakum (read in a browser, 2026-10-05): 'commanding a Waaagh! against Hive Prome'. NAME-COLLISION CHECK: no index record uses the id or label; Lexicanum has no Prome article ('There is currently no text in this page') and Hive_Prome redirects to Bakum.
typelow
'planet', standing for the hive and the unnamed world it is on. 'Hive Prome' is the only name any permitted source gives; none says whether Prome is a hive city on an unnamed world (the 'Hive Primus' pattern) or a hive world. The record is not made unplaceable on the Broucheroc precedent because there the sources name the city AND call its world 'the planet'; here the book names Hive Prome as the place the Waaagh! is fought ('on Hive Prome'), which is SCHEMA.md's 'a world the book NAMES but canon never locates'. NEEDS CHECKING against the novel.
classlow
Painted `hive` because 'Hive' is the one descriptive word any source gives for the place; no permitted source describes its terrain, climate or colour. `dead` (the dataset's unnamed war-world default) was refused because the name itself says hive; `fortress` because no fortification is described. A reasoned look, not a published one.
segmentumhigh
null, stated rather than guessed: no Lexicanum article, Warhammer Community post or Black Library description gives a segmentum, sector, subsector or system.
gposlow
inferred: named in the book's own description and unplaced anywhere else, with no segmentum, sector, subsector, bearing or theatre published. Unsurveyed rim (rim_xy('hive-prome'), r = 432.2 of the 470-unit disk, outside every stylised segmentum polygon), no positional information. Z -6.3 is the zPolicy value (compute-z.mjs hive-prome 289.8 122.4).
systemIdlow
'hive-prome', named for the place because no system is published. no-system-survey: canon enumerates nothing about the system (no star, no other body, not even a body count) on Lexicanum, Warhammer Community or Black Library's description, so no systems/hive-prome.json is authored; an invented one-star-one-planet file would claim more than the sources do.
eraslow
indomitus only, and the date is the shelf's, not the book's: no permitted source dates Bakmun's Waaagh!, and Lexicanum's List_of_Media_set_during_the_Era_Indomitus does not list the novel. The book is filed M42 — Post-Great Rift with the run's other undated modern Ork novels (Warboss), after Prophet of the Waaagh!, whose forging of Ghazghkull it names as already done; Lexicanum Grotsnik carries his history into the Dark Imperium. Allegiance 'contested': an Ork Waaagh! is being fought against the hive; who holds it is not stated. NEEDS CHECKING against the novel.
