Emperor's Children warship, seized by Fulgrim
A warship the Daemon Primarch Fulgrim takes from its previous owner in M42 and uses as the meeting place for the scattered Emperor's Children he calls back to his side, the Perfecti warband among them, before the campaign against Crucible.
Position: Crucible System (Crucible) Fulgrim's seized warship, where he gathers the Emperor's Children he summons for the challenge of Crucible. Docked at the campaign it summons them to; no source gives the ship a position Cited in Fulgrim: The Perfect Son
Position

wh40k.lexicanum.com/wiki/Vexation (read directly in a browser on 2026-10-03): 'an Emperor's Children's warship, that was seized from its previous owner by the Traitor Legion's Daemon Primarch, Fulgrim, in M42. Fulgrim later used the Vexation as a meeting site for the Emperor's Children's forces he summoned to his side', cited to Fulgrim: The Perfect Son (Novel), ch. 1; Lexicanum Mauvais and Marduk_Tamaris (ch. 1): Mauvais tells Tamaris that Fulgrim is summoning the Emperor's Children to him aboard the Vexation. NAME-COLLISION CHECK: no index record uses the name.
archetypelow
'battleship', the generic capital-hull shape: Lexicanum calls her only a 'warship' and names no class, and a Primarch's seat is a capital ship; none of the named hull families (gloriana, rock, craftworld) is claimed for her.
positionslow
inferred: no permitted source places the ship. She is docked at Crucible because that is the campaign Fulgrim summons his sons aboard her to fight (Lexicanum Vexation, Mauvais, Marduk_Tamaris, ch. 1; Crucible_(World)). The dock is editorial and says only 'with the Legion she gathered'.
erashigh
indomitus only: Lexicanum dates the seizure to M42 and cites only this novel. Allegiance 'chaos'.

A ship gets no `systems/<id>.json`: the map draws ships as holographic schematics docked in the system their era-position names, never as a world with a body list.
