Tower is the official city of Magi. It’s not known where exactly Tower resides, as the mages who live there have been known to come from The Empire, Pinkyland and the city-states North of The Wilds. The Tower is lead by two Gnomish brothers, a Wizard and a Sorcerer, where all things Arcane are welcome. The prime goal of the inhabitants is research and learning, which sometimes puts the morals of better judgment aside. Access to the city is tightly guarded and to even have citizenship one must show Arcane abilities of some type. (Yes, even the chimney sweepers and garbage men are Arcane casters of one type or another!)
Every couple of years groups of the less knowledgeable common folk that live near one of the Tower Mountains will gather a mob to assault it and “Rid their land of the arcane evils!”, usually to never return or return hungry and depressed, not having found a thing.
[GM Note]: Any PC wishing to make a character from Tower must check with the DM first. It is not discouraged in any way but there are strict rules to being a citizen of Tower and it will need to be decided if you are an active citizen or a fleeing mage. As it is a city that works hard to stay secluded, I would never allow a PC that is created just to give away the location(s) of the city.
