The Triwizard Tournament has returned to the Wizarding world. Along with a power stronger than the Witches and Wizards. Demigods have entered Hogwarts, and The Triwizard Tournament would be more interesting than it was before and quite possibly a lot more dangerous. Sequel to A Deadly Magical Demigod (Discontinued!)

What if instead of being demigods, the Seven were wizards who were accepted at the age of eleven to Hogwarts School of Witchcraft and Wizardry? Though instead of separate adventures, they get one adventure with double the danger. This time however, will they be able to survive or will they all rue the day they got their acceptance letter?
