The Zamorak Magical Institute ("ZMI") is a Zamorakian organisation which specialises in magics and runecraft. Its main goal seems to be to arm Zamorakian magic specialists with runes and to gain access to the Rune essence mine by stealing the incantation for the teleportation spell to the mine from the Wizards' Tower. They have taken possession of the Ourania Cave and the rune altar therein, and control access to the Abyss. They seem to be active in the greater Varrock area. According to Savant, the Temple Knights suspect this organisation to be responsible for the burning of the Wizards' Tower in decades past and a number of other crimes.
