Three years after Voldemort's defeat, the N. E. W. T. Exam at Hogwarts mutated and turned into a deadly survival game. Harry Potter and Draco Malfoy were forced to team up and struggle to survive in the magical restricted area constructed by the system - the hundred dementors in Azkaban, the blood test of Malfoy Manor, the reanimated Hogwarts Castle... What is even more frightening is that their wands were forced to exchange, and the black curse marks on their wrists were devouring magic and memory.
When Dumbledore's memory fragments reveal that this test originated from Grindelwald's "memory immortality", and when the shadow of young Riddle awakens deep in the secret chamber, Harry and Draco must face each other's darkest past. Can the wands of holly and hawthorn resonate in the curse? When the countdown to the final examination room reaches zero, will what awaits them be redemption or eternal magical assimilation?
Concept: When rules become shackles, the real magic is the contract to defeat fate
