‘We entered the Eternal Fortress as a Legion,’ Ezrachi said. ‘We left as a multitude of Chapters. It pained the primarch to do this, but he knew it was necessary. Dorn himself presided over the first of the centenary Feasts. He wished successor Chapters to maintain good relations and a cult brotherhood. This commitment was re-honoured following the Daedalus Crusade. Our brothers from participating progenitor Chapters were invited to attend, and many of the Feast’s present rites and rituals were established. We know that Rogal Dorn broke the blade he’d used on Horus’s barge, after it had failed to protect his Emperor. His second sword, the weapon to which we refer as the “Sword of Sebastus” or the Dornsblade, emerged with the primarch from the Iron Cage. It is one of our most revered artefacts, a weapon carried and used by mighty Dorn himself. The Chapter that wins the Feast has the honour of retaining the blade and the solemn duty of presenting it at the next Feast – the contest they will host, at most, one hundred years later.’
