This is a plain stone room with many trunks piled high.  There's tables with paper records stacked high along with writing instruments.

I am a worker and I work outside of the village.  I do any job that comes my way, sometimes for money, sometimes for food.  I do not have a family yet, I am waiting until I have a steady form of work.
I may be able to help you with that, as I take on a wide range of jobs. But, do you have anything to offer me if I get you out? I will give you all of the paper in this room if you help me escape! Ah but what are these papers records of? And what have you done to be imprisoned here? I have been falsely accused of stealing. These records are maps of all the treasures in the land. Only I am able to decode these maps. If you help me escape the treasures are yours! Let's write up an agreement with one of these pens. Do we have a deal? But, Will you decode them for me? If not how will I be able to find the treasure? I have a daughter and two sons who need me! If I don't get out of here they will starve. I will teach you how to decode them once I am free. How can I trust you? Here, I shall write up an agreement, that you must sign with your blood. You have my word. These maps contain the locations of all the riches your heart can desire. I will gladly do so! Okay, whilst you sign this agreement with your own blood, I will carve these trunks into kegs that will unlock the door. Thank you, kind worker! You will never have to work again after finding all of the treasure!  I wish to have a family one day, I would never want to keep you from yours. You are kind! Thank you so much. I never thought I would see them again.
