Krade

Krade is an Ultima Imperial world the Iron Warriors turned into a delaying fortress against Guilliman's march in the Horus Heresy. This pin is that Slaves to Darkness meat-grinder, not a random Krade hive with no primarch on the ledger.

Perturabo spent months here stopping Ultramarines and Imperial Army veterans from reaching Horus's rear. Argonis arrived with orders to drop the siege, find Angron, and muster at Ullanor. The Lord of Iron withdrew most of the IV and left Soltarn Vull Bronn holding a war he had already paid for in warsmiths.

Krade still matters as a named Iron Warriors roadblock on the road to Terra. Unofficial fan summaries keep the Ultima parent and do not pretend the pin is Olympia, Medrengard, or a later 40k backwater with the same hiss.
