A bland and not very imposing door is the only means by which one exits the tower. There is nothing special about the entrance - it is a simple stone arch. A broom and mop bucket are next to the door that leads to the outdoors.

groundskeeper
I am the groundskeeper. I maintain the grounds and prepare the yard for jousts. I also help to carry away the bodies.
I'm quite disturbed, archer. Among my duties is to transport the bodies away, but I'm afraid I have lost one near this tower entrance. Lost one what.  A bodie? Yes! The body of the wench from Fairside. She was on my cart, and now she has disappeared. I turned my back only for a minute, just to eat a small snack. What are these people dying from? Cholera, plague, any number of infections. But that's hardly the point. Where is her body? I've searched all around the entrance and I see nothing unusual. Have you tried climbing the tower for a better vantage? Indeed, that might be a solution to my troubles. You are a wise man, archer.  I spend much time int the towers, being an archer: Better to snipe the enemy! Yes, that makes good sense. I do have a slight suspicion. Perhaps she was not quite dead yet. Why is that? She was making some rumbling noises. You know, sometimes bodies do that, but hers seemed louder than usual. You didn't check? You might want to retrace your steps.  I could help you.
