The Bloodborn was an alliance of the Forces of Chaos comprised of multiple Chaos Space Marine warbands and rogue regiments of Planetary Defence Forces and Imperial Guardsmen. The Bloodborn was jointly led by the Iron Warriors Warsmith Honsou and the Daemon Prince M'kar the Reborn. The rest of the Bloodborn's elite forces were comprised of Chaos Space Marine warbands which included the Skulltakers, the Apostles of MinthRas, the Claws of Lorek, and the Death Shadows. In 999.M41, the Bloodborn assaulted the Ultramarines' Realm of Ultramar in the campaign remembered simply as the Invasion of Ultramar.
- Invasion of Ultramar (999.M41) - The Invasion of Ultramar was launched by a large Chaos warband known as the Bloodborn, who invaded the Ultramarines' Realm of Ultramar. The invasion was jointly lead by the Iron Warriors Warsmith Honsou and the Daemon Prince M'kar the Reborn, both servants of the Ruinous Powers who had sworn revenge against the Ultramarines for past wrongs they believed had been done to them. The Chaos invasion occurred roughly concurrently with Abaddon the Despoiler's 13th Black Crusade in 999.M41. The Bloodborn's invasion was not officially a part of the Black Crusade's forces. Ultimately this quest for vengeance was foiled, as Honsou escaped and M'kar was banished back to the Warp by the Ultramarines.
The Bloodborn warband used a variety of colours because of its mixture of Iron Warriors and other Chaos Space Marine warbands.
