The Tower of Reason

This imposing structure at the northern apex of The Jence Wall is the largest building dedicated to the study of wizardry outside of Eal . It stands 150 feet tall and is embedded into the walls structure. Unlike the rest of the wall it is not built an equivalent distance into the ground. It contains nine levels connected by a central spiral stair. The second floor is a bedroom and living area, the fifth is an engineering laboratory that is still in use, and the highest level contains a teleportation circle, observatory and operation stations for the tower's arcane defences. The other levels are either libraries or laboratories dedicated to various magical schools. Despite being a master transmuter, the tower's builder - the arch-wizardess Polina Mikalan, known as 'Reason' - stored most of her studies on transmutation in distant Tempus Fugit and dedicated this tower to study of illusions.

The tower has four entrances - two leading to the connecting walls on each side, a main entrace into the city from the south, and a service gate to the north that leads outside the city. The service gate is only 4 feet across and 10 feet high and leads into a defensive labrynth on the ground floor of the tower. It was build mostly to provide small parties a rapid means of reaching the safety of the city when fleeing danger from the north wastes.

The top floor of the tower is the last known location of Reason. She entered a hundred years ago in the company of Whisper and never came out. This not being unusual for a wizard capable of teleporting, no efforts were immedietely made to check on her wellbeing - but she has not been seen since.

Reason was the world's foremost expert on Transmutation and her magic continues to strengthen the walls. This is achieved through a focusing iris in the form of a massive ruby mounted in an arcane machine on the fifth story of the tower. The spell renders the hardened granite of the walls unbreakable by non-magical attack. It is unknown if the ruby alone allows the spells continuation, or if its persistence is a sign that Reason still lives to maintain it.
