The inside tower is made from a combination of wood and brick. It also has some metal to hold all the doors in place. There are three doors and a staircase that leads up to the guards quarters.

rabid rat
guard
I am a guard at the royal castle.  I am brave and strong.  It is my duty to protect the king.
What are you doing here rat? I do as I please! I am the scourge of your kingdom! Back off! or me and my friend will kill you. You can try, but not before I've passed on the plague! Soon you'll be sick like everyone else in the village! You insolent rat! You have rabies not the plague!  I have both, which means I'm angry and deadly! Me and my knight friend will know cut your head off and feed it to the prisoners!  Now I have the sword! But if you are willing, I will consider a truce. Get me some scraps from the king's table and I promise not to get too bitey. You fool! I am simply a guard, I cannot steal from the king himself! The more excuses you give, the more I want to bite! Fine, fine... I will fetch you some cheese from the dining hall. Yes, thank you! and some bread.
