The Tower stands tall, built of the best stone with a number of odd runes that only the local mages truly know how to read. Despite age the stones do not crumble, and stand ever vigilante as a watch station for the city.

I am a guard at the royal castle.  I am brave and strong.  It is my duty to protect the king.
Hello. Who are you? I need to know who you are before letting you in here. I am Karest the Great, I am the best of all mages! Why do you come to this city. I am here to show my greatness of course. I will kill you if you try to harm anyone here. Harm, no, I am here to assist.  See my powers come from the runes in old.  I can harness them through my staff of gold. I see. Can you read these runes? We have been trying to decipher them for many years now. I believe I can.  My staff has the power of making the writing of old readable in the language of the commoner.  Let me show you. Thank you, mage. I have heard rumors that they can help our land be wealthy and strong. This is what I have come to you town for, to help you regain you powers of old.  Nothing at all in it for me!
