With the last of the invaders dead, Kyra lowered her bow and looked towards Parum and the prisoner. Without a word she walked over to the two, picked up the raider and went inside the fortress. There was no time to waste; once the door was open Kyra took the raider to the prisons. As she walked past everyone she let them know where she was going to be at. "I'll be interrogating this one at the prison. If you'd like, I could use your help getting some answers from her. I'd certainly like to know who leads this army and why they're doing what they're doing." Kyra dragged her guest away, and once they reached the prison she wasted no time binding the unconscious raider in chains. Kyra was actually quite familiar with the mechanisms, as they used a similar sort of thing when slaughtering cattle. And if this prisoner doesn't cooperate, her fate would be just the same.
Kyra waited at the prison for the raider to awaken or for the others to come, which ever came first. There was already some "tools" here she could use to begin the interrogation, though it still relied on the prisoner waking up first. So Kyra just sat in a chair across the prisoner, waiting.
