Monsters University - A Message From the Dean

Synopsis
Established in 1313 following a land grant from the city of Monstropolis, Monsters University has grown from a small local center of learning to a leading global institution of higher education. Upon this hallowed ground, some of the most fabled academic buildings in the world have been built, serving the hundreds of thousands of alumni that have walked the halls and grounds of MU.
