The young man shakes his head. "I kept the keep in order as is my duty. Nothing more."
"Did you take part in the slave trade done here?"
"Lucas, my [lord/lady]. I have served here since the forging of my chain in Oldtown. As a maester is tied to his keep, not its owners, consider me at your disposal."
"Be warned. At the first sign of treachery, I will mount your head on a pike."
"I trust your story, Lucas. Please, allow me to introduce you to my family."
