Voidship carrying pilgrims of the Spiral Dawn
A voidship on which a weary former Guard officer has taken passage on his long journey home. Some three months into the voyage a congregation of the Spiral Dawn's pilgrims comes aboard in his section of the hold, and he goes down with them to Redemption.
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/Ambrose_Templeton (read directly in a browser on 2026-10-03), section 'Iron Calliope', citing Cult of the Spiral Dawn (Novel), ch. 1: 'Roughly seven years into his journey home, Templeton took passage on the ship Iron Calliope. About three months into the journey on the Calliope, a group of pilgrims had entered the ship in his section, members of the 42nd congregation of the unfolded'; he builds himself a shack from the cargo hold and meets Ariken Skarth there.

m41, docked in the Vytarn (Redemption 219) system: the pilgrims she carries 'journey down to Redemption 219' by shuttle in chapter 2 (Lexicanum Ambrose_Templeton, ch. 2). That she is the ship in orbit when they do is read from the sequence, not stated.
classmedium
No `archetype`: no permitted source names her class or hull, only that she carries passengers and cargo (a cargo hold, Lexicanum Ambrose_Templeton, ch. 1). The map draws the default schematic, as for the unnamed penal transport of Perdition's Flame.
erasmedium
m41 only, the era the shelf files the novel in. Allegiance imperium: an Imperial passenger voyage of a sanctioned sect.
