Amon

Amon served as equerry to Magnus the Red, a captain of the Thousand Sons trusted with duties that reached far beyond the battlefield. It was Amon to whom the Crimson King entrusted the guardianship and tutelage of matters closest to the Legion's soul, and he came to occupy the role of a conscience at his primarch's side, the voice that questioned where others simply obeyed. A capable warrior and a gifted adept in his own right, he was nonetheless defined less by his sorceries than by his loyalty and his unease.

For Amon saw, more clearly than most, the dangers in the powers his primarch courted, and he wrestled with the tension between his devotion to Magnus and his dread of where that devotion might lead. When Prospero burned, that inner conflict was consumed along with everything else, the equerry forced to fight for a Legion already sliding toward damnation. In the tragedy of the Fifteenth, Amon stands as a figure of divided loyalty, a warrior who loved his primarch enough to doubt him, and who followed him into ruin all the same because he could conceive of no other path.
