In the span of fifteen days, Boreas and his [[Librarian]] assistant Samiel pried at Astelan's mind with pain, torment, psychic abilities, and questions designed to undermine Astelan's view of the events that occurred, trying to get him to admit his sins and repent. Astelan struggled and survived, explaining much about the past of the Chapter and the old Legion before the Heresy. He explained that it was his order that set Caliban's guns ablaze against Lion El'Jonson's fleet when it returned, and he revealed that it was his voice that was lent to [[Luther]] when the [[Space Marines]] on Caliban were uncertain that they were being led in the right direction while watching over the planet.
