Time is the most magical magic in the world. It allows four people to travel through thousands of years and meet at the end of time. The love that was never spoken thousands of years ago and the regret that was never embraced are realized at this moment.
Harry Potter: Salazar Slytherin
Draco Malfoy: Godric Gryffindor
Hermione Granger: Rowena Evenclaw
Ron Weasley: Helga Hufflepuff (gender change)
Before they traveled to the millennium at the age of seven, time magic blurred their memories of the millennium before.
After creating their own glory thousands of years ago, they were sent back to their own time by time magic to create new glory again.
Manyue is me.
Concept: Time is the most magical magic in this time.
