Kalion Observatory, the Secret Judgment Division (秘儀裁示局・天文台カリオン, ?) took place in the oldest classroom of the Clock Tower. They decide on the Sealing Designation and also the procedure of revocations. At the end of the 20th century, they delivered an incredible shock to the entire Clock Tower as multiple sealing designations were revoked.[6]
The actions of those who are designated can be divided into two paths: Hermit (隠者, inja?) and Philosopher (賢者, kenja?). Hermits become degraded magi after secluding themselves from the world, transmitting their knowledge only to their successor. Unless they have a truly extraordinary work, they are normally left alone by the Association because they are not an immediate threat, instead only kept under surveillance while keeping an interest in their research. Philosophers are those great magi striving to reach new heights, becoming menaces that abandon all codes of conduct to continue their research without being bothered. Acting without restraint unlike normal magi, they are able to obtain greater results in a shorter period of time. They may victimize a number of innocent people in their pursuit, possibly making magecraft known to the world should they be too careless.
