The Eternal Magician of the Elven Queen

The young Orion died saving people, and unexpectedly won the favor of the Elf Queen, and brought him to the continent of Faerûn for resurrection. With the great mission of saving the royal court, the boy signed a contract with the queen and became a magic binder, and then embarked on a journey of adventure. ... The putrid shadows wandering in the night, the "plague zombies" born from the intertwining of flesh and plants, and the invisible crisis quietly swept the entire village. ... The classmates who died one after another and traveled through time were thrown into this continent like chess pieces in a game. Is it a coincidence or intentional?
