The Assassin's Blade
The Assassin and the Desert
Celaena recalls the meeting with Arobynn Hamel in which she explained what she and Sam did to free the slaves in Skull's Bay. A furious Arobynn summoned Tern, Harding and Mullin into the room, then commanded Harding to close the office door. Tern and Mullin followed Arobynn's orders to restrain Sam; Harding stood in front of them and threw his arm in Sam's path when Sam began struggling as Arobynn beat Celaena.
The Assassin and the Empire
Celaena hears Tern, Harding, and Arobynn discussing an apparent retaliatory strike against Ioan Jayne and Rourke Farran. Harding observes that the crime bosses will anticipate retribution for Sam's death from the Assassin's Guild. Arobynn proposes to kill Jayne and Farran in their beds, but Harding argues that reaching the second floor will be no easy task and suggests that the assassins enter via the second-floor window. Tern disagrees, but Arobynn asserts his leadership on them and instructs them to have the other assassins prepared and to be secretive about their mission.
