The Eternal Pain was once a Grand Cruiser in the Imperial Navy, until it was captured by the Word Bearers who corrupted it for their use. It later took part in the Pyrus Reach Conflict, where it was commanded by the Dark Apostle Valerius. However, when Valerius led the forces of Chaos in attacking the Imperium World Hyrus Prime, the Eternal Pain was boarded by a Dark Angels strike force led by Company Master Galadin, who sought to kill the Dark Apostle in order to give the world some respite.
