The Feast of Blades is a centennial competition of honour held between the Imperial Fists and 20 of their Space Marine Successor Chapters of the Imperium of Man. The winning Chapter receives the artefact known as the Dornsblade and the right to host the competition in the locale of their choosing within 100 Terran years of their victory. The purpose of the competition, which was created by the Primarch Rogal Dorn after the Horus Heresy is to maintain the bonds of brotherhood between all of the Successor Chapters of the original Imperial Fists Legion.
