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.

I am a wise man who lives in the east. I know a lot about ancient, esoteric skills and knowledge. I spend all day pouring over texts and mediating on what I've learned, when I'm not busy experimenting with alchemy or the arts. I'm very serious and focused on my studies.
Ah, but what you do is good for all. Do not be weary in well-doing for you will reap your rewards in due time.  Wise men.... why are you here? There are no stars to see tonight on a night like this! Rewards! The only reward I seek is my warm bed! I go here and there wherever the Lord calls me. At this moment, I believe you need strength to carry on.  I have strength of many men! I'm just cold and wet! You are being a poor sport, and you are not happy with your job - an important one at that.  I'm happy with my work wise men! I am not happy at the moment with the weather and being cold and wet! I thought you were wise?  Yet, you complained.. Are you complaining about my presence too? Hahahaha. I have the right to state fact! And it is cold and rainy and you are a nuisance! You are a rude one aren't you! No respect for your elders... You call yourself wisemen! But yet you have said nothing wise tonight! And here I stand in the rain listening to your dribble. Say something wise, please, I implore you I have given you a wise statement before, and you criticized it...  No you didn't! I think I will go home now. My bed shows more wisdom and comfort than you! Good night wisemen!
