Master Ey debuted in Knowledge, where he was shown as Beyal's master. At the end of the episode, he allows Beyal to go with team Core-Tech.
In Light, it was revealed in the end that Master Ey had hired Dawnmaster to infiltrate the Library of Tebab and replace all of the books with blank copies, which was why Dawnmaster came into conflict with Team Core-Tech earlier in the episode.
In Ice, he sent Team Core-Tech on a mission to retrieve Beyal's soul from the astral plane by taking his body to the Cave of Convergence. At the end of the episode, Master Ey was shown observing a mural on the temple's wall, saying that the Destiny of the Five Tribes has begun.
