It is completely without windows and, due to several repairs over the centuries, it has a gnarled appearance, much like an ancient yew tree. Atop it sit several small turrets and crenellations and within its stones entire ecosystems have formed, including species unique to the Tower of Art. A lack of predators willing to climb the vast heights of the tower has meant that several species of insects, birds and small mammals have been able to evolve fairly unaffected by the outside world, except by the magical waste from the university, causing some very odd results in the evolutionary pathways of these animals.
