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.
Within the walls of the city, Inside Tower
mage
guard
I am a guard at the royal castle.  I am brave and strong.  It is my duty to protect the king.
You will have to give me more information if you don’t want your head to be displayed on a pike at the city gates. I am a guard here, what are you doing within the city walls? How dare you threaten the only real mage in this city. You'd better let me through if you don't want me to strike lightning through your heart with my golden staff!  Calm down, fairy boy. Prove to me you are a mage and tell me what you are doing here. If you comply I will even help you. I'm not just "a mage," I am the only real mage in this city! Have you ever noticed how the stones in your guard tower never crumble, even though it is constantly used? Guess who is responsible for that work! If you speak the truth, tell me what this runemes I would but my breath would be wasted. I could say it means "stability" as a whole, but every rune is made of thousands of smaller runes that give it power. Alright, I believe you. Where are you trying to go? I have been guarding these walls for years, I can guide you. I don't need guidance from the likes of you. Please just do me a favor and disappear before I make you with my staff. Thank god there is only one of you. The king will hear about this. Why are you wasting your time interrogating a respectable great mage like me when there is a literal goblin behind you? What's the deal with that anyway? This is Doobah, he is my pet goblin. Does such a small creature scare you, o’ great mage? Of course not, but I know many spells that could make him the stuff of your worst nightmares!
