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.

It's your watch, sire. I did my shift. Mind the ramparts in this rain, they are bloody slippery!
Hello I am a wise man who lives in the east. I know a lot about ancient, esoteric skills and knowledge. what brings you? Brings me?  I hold a Watch at this Watchtower, which is why they call me a Watchmen.  Some wise mean climb the great heights here to observe the stars.  Is that why you are here? oh. I dont know you the watchman. I expected a much more older man You mean the court wizard?  He does magic, but his eyesight it poor - he would not be a very effective watchman. alright, I know better now.  Well, you can't be called wise unless you learn every day. I have an important question to ask you...dont know if i will get the truth! Ask away oh wise ones. You the watchman, have you seen any strange persons of late? There are some which appeared before me very recently, which I fear may be very strange indeed. and did you report this to the king?
