 Based on the sky island of Caroban, the College Esoterica is a center for organized magical study on Sinai, dividing the arts of Sinai magic into various "spheres" in which wizards specialize. To be a spellcaster without sanction by the College Esoterica on Sinai is to invite trouble, as the College jealously guards its position as the keeper of the secrets of the mystical arts.
