Rayfalke Spiritcrest
Mikleo goes to the Galahad Ruins in search of the legendary Divine Artifact that can suppress evil spirits. Meanwhile, after parting ways with Alisha who is headed for Marlind, Sorey goes to Rayfalke Spiritcrest which appears in dragon folklore. There, he encounters a young seraph named Edna being attacked by a hellion. Sorey and Lailah confront the hellion, but the Malevolence is too strong and they cannot deliver a decisive blow. Suddenly, another seraph named Zaveid appears and makes quick work of the hellion, declaring that killing hellions is his style. When Sorey objects, the seraph cryptically counters with ”Maybe some are saved by killing them.”

Tales of Zestiria the X
Sorey is a human youth who grew up among the seraphim, spiritual beings not visible to humans.
Sorey believes in the folklore that says “long ago, every human was able to see the seraphim" and dreams of unraveling the ancient mystery to make the world a place where people and seraphim can live together in peace.
One day, Sorey visits the human capital for the very first time. He becomes embroiled in an incident during which he pulls out a holy sword embedded in a rock and ends up becoming a Shepherd, one who casts away calamity from the world.
He begins to realize the gravity of his mission, and his dream of coexistence between mankind and the seraphim becomes more intense—
And thus, the Shepherd embarks on a journey with his companions.
