An enormous tower that has been around for many, many millenniums. It contains volumes of dangerous books, many dangerous magical artifacts, is home to various trials that help improve a magician's power and rank.
The tower was originally used to train those without magical properties to use and manipulate magic like a wizard and other such creatures. After the events of 2000 years past and the sealing of the Tower of Wizards, the mages of this tower take in both those whom wish to use magic and those whom are born with magic. It wasn't until recently with the seals on the Tower of Wizards being broken that they started seeing less and less wizards come to seek training here.
The tower is rather easy to find, as it is in one of the very few ares of Lenoria that isn't touched by the Laurentile Forest.
