The confessional room is small and cramped, offering access to only a single person at a time.  Once inside this small, wooden room, A person is alone with nothing but the cardinal and their own sins.  The confessional room has a single wooden bench and small table holding a candle, with a sliding window that allows words to pass through to the other side.  The cardinal waits on the other side, ready to absolve someone of their sins.

I stay hidden near the old bridge. I guard the old bridge and harass un-expecting passers. I am short and ugly and no one wants to make me angry.
"Why you bring me here?" I wish to offer you a chance to confess before you are brought to the town square for your execution. "Me guard bridge, me home. Is that sin?" According to the King it is, sir Troll. "Is king the decider of sin?" He is the decider of law. And I am his vessel, carrying out the law. Without laws, all would devolve into sin. "Is against the law to own a bridge?" No. The King owns the bridge, not you or any other troll. "Why king own bridge? Me father live under that bridge and his father too" I am afraid that appeals to freedom are useless. You will confess, or not. You will be executed. Are the ready? "Is killing not also sin?" Perhaps. But that hardly matters now.
