Space hulk; Ghazghkull's exodus ship
A space hulk with a warp rift where its engines should be, packed with daemons. It emerges in orbit around the dying Urk, Ghazghkull's horde secures it to a moon with traktor kannons and harpoon rockets and ferries billions aboard; the young Prophet defeats a Bloodthirster, headbutts the rift shut and names the hulk Wurld Killa. It carries the Waaagh! through the warp to Armageddon, where a force-field built in transit lets it crash-land, in Ghazghkull Thraka: Prophet of the Waaagh!.
Position: Zornian System (Urk) A daemon-infested space hulk emerging over the dying Urk; Ghazghkull's Orks lash it to one of Urk's moons, board it, beat a Bloodthirster and headbutt its warp rift shut Cited in Ghazghkull Thraka: Prophet of the Waaagh!
A mobile record: it carries a position timeline rather than a fixed point. The archive places it in 1 of the four eras (M41); each era section above carries that era's entry.

wh40k.lexicanum.com/wiki/Wurld_Killa (raw wikitext through a browser, 2026-10-05): 'a Space Hulk famously acquired by Warboss Ghazghkull near Urk in order to invade the world of Armageddon', infested by daemons through a warp rift at its centre, the Bloodthirster defeated and the rift headbutted shut (Ghazghkull Thraka: Prophet of the Waaagh!, Chapter 4), crashing into Armageddon at the second invasion (Waaagh! Ghazghkull supplement, Exodus). Lexicanum Urk and Ghazghkull_Mag_Uruk_Thraka, Exodus, cite the moon-mooring and the boarding to Chapter Six. NAME-COLLISION CHECK: no index record uses the id or label.

VISITED for Ghazghkull Thraka: Prophet of the Waaagh!: the boarding, the Bloodthirster and the departure from Urk's orbit are told in Chapters 4, 6 and 8 (Lexicanum Wurld_Killa, Urk, Makari: 'Aboard the Space Hulk known as Wurld Killa, Makari witnesses Ghazghkull defeat a Bloodthirster of Khorne', Chapter 8).
positionshigh
m41 in the Zornian System (orbit of Urk) and then the Armageddon system (Lexicanum Wurld_Killa; Ghazghkull_Mag_Uruk_Thraka, Exodus and Second War for Armageddon). The warp transit between has no position.
classhigh
No archetype: the map's hull table has no space-hulk family, and the nearest ('rock', an Ork asteroid fortress) would draw the wrong thing. Left absent, as 29 other ship records are, until a hulk archetype exists.
erashigh
m41 only: the exodus and the crash both precede the Second War for Armageddon in 941.M41 (Codex: Armageddon p. 25 via Lexicanum Ghazghkull_Mag_Uruk_Thraka). Allegiance 'ork'.
