When the 6th Founding commence, the Imperial Fists, led by Captain Mocar of the 3rd Company, founded a chapter called the Imperial Centurions. One of their closes allies at the time was the Chapter that is now known as the Knights of Chaos. The Knights of Chaos betrayed the Imperial Centurions by attacking their homeworld of Fellon. Only aid from the chapter’s successor chapters came to save them driving off the traitors. Since then the Imperial Centurions have sworn vengeance after the death of their Chapter Master Mocar.
Imperial Lancers are a special unit in the chapter. They consist of marines on bikes with large lances that are identical to power swords. They are led by a sergeant and usually form tight formations during a charge, only to separate when they near the enemy.
Unlike other chapters who have successors, the Imperial Centurions and their successors share the same sector for recruiting and thus protect it as well.
