Ark Mechanicus of Satzica Secundus
An Ark Mechanicus from the forge world Satzica Secundus, named in the war for the lost forge world Velchanos Magna. No permitted source says where she sails, so the map admits her rather than placing her. What becomes of her is kept off this record because it would spoil the book.

wh40k.lexicanum.com/wiki/Ark_Mechanicus (read directly in a browser on 2026-10-01): 'Encoronada — From the Forge World Satzica Secundus', citing Adeptus Mechanicus: Tech-Priest (Novel), 1000, DENTRICA I OF I, +NECESSITY BEGETS INVENTION+. NAME-COLLISION CHECK: https://wh40k.lexicanum.com/wiki/Encoronada has no article ('There is currently no text in this page', read 2026-10-01), and no other index record uses the name (it appears only in satzica-secundus's identity provenance).

No permitted source gives her a position in any era: the Ark_Mechanicus line says only where she is from and who controls her. She is not docked at velchanos-magna or satzica-secundus because nothing states either.
Allegiance 'imperium' for the ship of a loyal forge world at the book's opening, as for Opus Machina. Her published status, 'Controlled by the Dark Mechanicum' (Lexicanum Ark_Mechanicus, citing Tech-Priest ch. 1000), is part of the book's treachery and is kept off the record as a spoiler.
