HANNIBAL'S EVOCATION LEARNING LABORATORY
The school specializes in evocation and divination. They teach all schools of arcane magic (but shy away from necromancy).
Hannibal’s school draws the least amount of students of the three schools, but perhaps because it’s misunderstood. His spells and magic come from the cosmos. And only few understand the truer impact of that. It would empower someone to leave this world and travel from dimensions to dimension via spacejammers. It also could provide a specialized defense against aberrations.
Whatever the case maybe, he is a bit of a recluse but has never given anyone any reason do dislike him.
Typically, students who are invested in the school sing his praises.
