A tower in the countryside near Agister and once an esteemed center for magical learning in the Yore Valley Barony before that entity's destruction by the crystal forest. It is named for its characteristic slant. The archmage of the tower from 3320 AE to 3365 AE was Everwood Wand, succeeded by Studious Spellcraft. Emerald Hues accepted the position of archmage in 3548 and remains the current (as of PRPG3) archmage.
It is a graduate institution exclusively, granting the degree DM (Doctrix/Doctor Magicarum, "Teacher of the magical arts") during PRPG2. During the Harmonic Age, a new MM (Magister Magicarum, "Master of magical arts") degree option was created. The previously discontinued MV program was also reinstated to help supply qualified graduates for the notable alchemical industries of the nearby town of Agister.
A satellite campus, Cardioid Point, was built in 3572.
