History
The Iron Knights, formed before the Fourth Founding in M32, are a crusading Chapter. They send a champion to the centennial Feast of Blades and are the only Chapter to have won twice in a row. When the Iron Brethren turned to Chaos, the Chapter began a penitent crusade. In the War of the Beast they gave part of their strength to rebuild the Imperial Fists.
Notes
The Iron Knights treat war as a sport and like to test themselves in harsh environments against dangerous fauna and flora. Their homeworld Seheris consists of deserts and plains divided between several tribes.
