Casabon is a ancient half elf wizard that has been teaching wizardry through his life. He specializes in the elemental school of magic. Often hunched over and talking quietly to himself, Casabon appears to be mentally unstable, with a gambit of verbal and physical tics. In a conversation his attention often wonders, but often enough he will notice details that would normally be ignored by a more stable mind.
Casabon only teaches out of necessity to keep his position of power at the university. He cares little about his students, but will often claim credit for his past pupils achievements. There has been several prominent cases of Casabon involving his students in experimental spell casting, often injuring his students. These misdeeds are often overlooked because of his deep knowledge of elemental magic and years of service.
