Agamotto was the first Sorcerer Supreme of Earth, founder of the Masters of the Mystic Arts and the builder of the Sanctums and the Eye of Agamotto.
Real Name: Agamotto
Thousands of years ago, Agamotto was the first to discover the Mystic Arts on Earth. Then, he founded the Masters of the Mystic Arts and started training other Humans to control the Mystic Arts.
During his collection of knowledge and power, he came across an Infinity Stone that he used to create his personal relic, the Eye of Agamotto.
He also erected three sanctuaries on three different places of power around the globe in order to shield it from extra dimensional threats like Dormammu, the lord of the Dark Dimension.
Eldritch Magic Manipulation
As the first Sorcerer Supreme and the founder of the Masters of the Mystic Arts, Agamotto was an immensely powerful master sorcerer, quite possibly the greatest sorcerer in history. His understanding of magic was great enough to create his own powerful magical relics such as the Eye of Agamotto which allows sorcerers to harness the power of an Infinity Stone.
He also erected the Sanctums that can generate a powerful barrier that can protect an entire planet from extradimensional threats, even one as powerful as Dormammu the ruler of the Dark Dimension.
