The tower is the largest section of the castle. It contains an observatory for nighttime scouting, but is also used by the wise men to study the stars. Armed guardsmen are always to be found keeping watch.

armed guardsmen
I am the guardsman to one of the noblemen in the kingdom. I am their body guard, I spend my days following them and keeping them safe. I am a diligent, perceptive person and also very bright and resourceful.
Ugh that same drunkard? He needs help! He does but I am not longer in service.  I may even join him to unwind.   Here is the bag of bread my wife promised you.  She was very grateful for the extra thread to finish her sewing. You're welcome. Did she make a sheath for my weapon as well? You know she is not of good health as of late.  She speaks as though she is a child.  The sheath was too much for her in her child like state.  Agh! This bloody rain makes for a nasty evening. Oh that's right I forgot. I'm sorry, so many citizens it's hard to keep track sometimes. Oh I did forget.  A traveler passed through to see the king.  Said they were from the King's army in the west.  Looked legit. You what? You allowed sometime to enter without telling the guards? Should we sound the alarm?   I mean it seemed so late, and I hated to wake the guards. I think we should be fine. I'll do a search myself.  Oh good, because I'm off duty, and the drink she calls me. Mind if I join after my search? Ah and leave the tower?  I thought you guardsmen were all business.  I see the King has lost your loyalty as well with his foolishness.
