History
The Invaders, an Imperial Fists successor, destroyed the Eldar Craftworld Idharae in 852.M41 at heavy cost. Forty-three years later Alaitoc retaliated and overran their homeworld Ogrys; only three companies survived and the Chapter took to space. In 913.M41 they lost nearly all their Marines in Ahriman's trap on Jollana, fought the World Engine in 926.M41 and Tyranids at Verdox II in 999.M41.
Notes
The survivors of Jollana were mind-wiped to forget the incident. Losses such as two Terminator squads at the World Engine show the Chapter's assault focus.
