There’s little chance Daud and Corvo would ever have been friends. One’s an assassin who killed an empress, the other’s a bodyguard who failed to protect one. Two inherently opposing forces, with blood and Outsider marks on their hands. Put them in a room without bladed weapons though, and they’d find they had a lot in common. Corvo is fighting to redeem himself in the eyes of the city. Daud accepts his damnation, and is just shooting for a little personal redemption. Both men get their chance.
