Rogue Trader - The Koronus Expanse
The group's brains
An old friend of Felix and one of the original crew of The Stalwart Venturer, Callidon is effectively the second-in-command of the group. As a scion of the vastly powerful and wealthy House Benetek, Callidon pursues the path of becoming a Navigator beyond compare, a goal that is slowly but surely being realised.
A man of opposites, Callidon is courteous and deferential to the point of being self-effacing in formal, high-class situations, but views the vast majority of common, lower-class people as expendable cattle. Callidon is not a nice person, and his servitor bodyguard (amongst other things) makes him dangerous to cross.
