After the death of Cedric Diggory, Hogwarts is chosen to host the Triwizard Tournament for the first time in thirty years. Because of the events that occurred last tournament, Beauxbatons and Durmstrang refuse to take part. The two competing schools are known as North America's Ilvermorny and Japan's Mahoutokoro.
Hundreds of ecstatic students enter their names, including Hogwart's own Jungkook, Namjoon, Calypso, and Taehyung. One evening, Namjoon shatters the goblet, transporting him and eight others to the past.
Stranded in the year 1294, all of their names have been entered and randomly chosen, forcing one them to take part in the tournament. With each new task won, they are all transported to another point in time. One more person will be chosen to participate.
Kim Taehyung, Park Jimin, Jeon Jungkook, Jung Hoseok, Kim Seokjin, Kim Namjoon, Min Yoongi, Natalia Malfoy, and Calypso Seraphine must compete with time in order to survive and return to the future.
