This archive tracks four layers. A record present in 3 of them (HH, AoI, M41) is silent in the rest, and says so.

Flagship of Perturabo and the IV Legion
Built at Olympia and, by canon's own claim, able to end a fleet or a planet on its own. Perturabo helped design it and left the viewports out — he held that seeing the enemy added nothing to the arithmetic — then watched the Battle of Phall from an open launch bay in his armour because he could not help himself.
Position: Phall System (Phall) Perturabo's flagship at the Battle of Phall against Dorn's Imperial Fists Cited in Shadows of Treachery
Position: Iydris System (Iydris) Carried Perturabo into the Eye of Terror alongside Fulgrim on the expedition to Iydris Cited in Angel Exterminatus
Position: Sol System (Luna, Mars, Terra, Titan) Led the Iron Warriors' retreat out of the Sol System at the end of the Siege of Terra, badly damaged. Cited to Ashes of the Imperium ch39, which links.json drops as a galaxy-wide Scouring narrative with no single world — one chapter aboard this ship is not enough to overturn that

wh40k.lexicanum.com/wiki/Iron_Blood also records the ship at the First Siege of Hydra Cordatus, and this dataset carries Hydra Cordatus — but that record's era set starts at aoi and the siege reference sits in the Heresy narrative, so the position is not drawn rather than forced into an era the host world does not have
