Uriel Ventris of the Ultramarines has saved the world of Tarsis Ultra from the monstrous tyranids, but at the cost of his honour. He has broken faith with the holy tome of the Codex Astartes, the worst crime an Ultramarine can commit. The masters of the Chapter call for his death, but there may be one last chance for Uriel to reclaim his honour and save his life. A short story from the Legends of the Space Marines anthology.
