Regallus was a Hive World of the Imperium. The Crimson Sabres Chapter fought there with eldar pirates raiding its hive spires.[2a] The planet's Hives were enormous, astonishing even a seasoned Space Marine.
Later, the Crimson Sabres returned to the planet as the fallen Chaos Space Marines of the Crimson Slaughter during Abaddon the Despoiler's 13th Black Crusade; Regallus was invaded by the forces of Chaos and laid to ruin.[2b]
