An Agonic Collar is a sorcerous artifact of the Ancient North, reputedly crafted by the Mihtrûlic Gnostic School. According to Mandate scholars, the purpose of the Agonic Collar was analogous to that of the Uroborian Circle utilized by the Anagogic Schools of the Three Seas; namely, to inflict excruciating pain on the wearer should he attempt to utter any sorcerous incantation.
