The 41st Millenniumpre-Rift
chaos
Thousand Sons warship, Hacathai's command ship
A ship grown rather than built: raised on the Planet of the Sorcerers after the Heresy by the sorcery of Magnus the Red and the Legion's machine sects, more a thing of the warp than of realspace and described as half-alive. It carries Hacathai, Magnus's emissary, and a force of Rubric Marines out from Sortiarius to aid the Thousand Sons against the Pyrodomon (Ahriman: Undying). What becomes of it is kept off this record because it would spoil the book.

wh40k.lexicanum.com/wiki/Scales_of_Truth (read directly in a browser on 2026-10-03): 'a Thousand Sons warship. "Grown" at the Planet of the Sorcerers after the Horus Heresy through the magic of Magnus the Red and machine sects of the Thousand Sons, it is more a thing of the Warp than the Materium and is described as half-alive. The ship acts as the command ship for Hacathai, emissary of Magnus' (Ahriman: Undying ch. 2). https://wh40k.lexicanum.com/wiki/Hacathai: sent 'with a force of Rubric Marines aboard the Scales of Truth from Sortiarius by Magnus' (ch. 2). NAME-COLLISION CHECK: no index record uses the id or label.
offMaphigh
No position can be given: it sails from Sortiarius, but the page gives no system for the book's action. Not docked at sortiarius because nothing places it there during the book.
classhigh
a command ship of no stated class (Lexicanum Known_Vessels_of_the_Thousand_Sons: 'Command Ship ... Under the control of Hacathai'), so no archetype beyond the generic ship schematic is set.
erashigh
m41 only (Lexicanum Hacathai: 'In M41'). Allegiance 'chaos'. Its course after the Pyrodomon reaches it (Hacathai, ch. 2) is a spoiler and is kept off the record.
