Chapter History

Notable Campaigns

  • The Night of a Thousand Rebellions (992.999.M41) - Carefully seeded and stoked by Chaos forces, hundreds of uprisings all broke out on a single night across Segmentum Pacificus which became known as the Night of a Thousand Rebellions. Unrest raced like wildfire, consuming many outlying planets, but also supposedly secure worlds like Enceladus, Darkhold, and Minisotira. Imperial worlds thought impervious to unrest were beset by mass violence. Even the homeworld of the Lions Defiant Space Marine Chapter was lost to the anarchy caused by the coordinated activity of secret cults and frenetic agitators. Contact was lost with large swathes of the Segmentum as Chaos Space Marine forces moved in to take advantage of the discord they had orchestrated.
