Hogwarts: The STAGS Project {a Big Five & Harry Potter crossover}

(takes place 4 years after The Deathly Hallows Epilogue)
The STAGS Project - The Special Talents Association for Gifted Students
Its had been four years since Dumbledore's Army had risen up against Lord Voldemort and vanquished him, and all was well. Neville Longbottom was the new Hogwarts Headmaster, with Professor Minerva McGonagall still with the role of Deputy Headmaster. Harry, Ron, Hermione, Teddy, Ginny, Luna, Seamus and all of your favourite characters teach classes in Hogwarts. And its that time of year again when a new shipment of students arrive at Hogwarts. But this year, it will not just be a bunch of babbling first years. There will be a small collection of gifted students asked to attend Hogwarts on a special programme too.
Pitch Black, Mother Gothil, Drago Bloodvist, Prince Hans and Mordu have all banded together to form a group of super advanced villains, all with special connections to Lord Voldemort, and all seeking revenge on Hogwarts and a select few people in it. You guessed it. Somehow, and in some way, The Big Five, a.k.a Jack Frost, Merida DunBroch, Hiccup Horrendous Haddock the Third, Rapunzel Corona and Elsa of Arendelle, will end up together as a team. Whether they like each other or not, for a new group of heroes is needed to rise up against a new group of villains. A new association, created by the ex-Dumbledore's army, called the STAGS.
However, Hogwarts needs to keep all this a secret, so the new STAGS representatives (Jack, Merida, Hiccup, Rapunzel and Elsa) will have to attend the school as normal, just like the other students.
Join The Big Five, the Harry Potter characters and the new villains in their journey through a new year in Hogwarts.
