Loken freezes, as if in shock, then goes silent for a moment, as if uncertain how to express himself well in this moment. He decides unvarnished, non complex truth is best. "Yes, I have. That has been the hardest war of the many I have fought, in fact, and the one that has threatened the Imperium of Man." He just leaves out the fact that he's seen his best friend, the only woman he ever loved, and the very beginning of the fall all described as exactly that, at varying points in his battles.
