Harry Potter and the three mysterious teenagers

The 'Golden Trio' returns for yet another year in Hogwarts, since they didn't learn much the last year. Unfortunately after the war with Voldemort, the three best friends weren't the same anymore. Their fame made them selfish people with big egos. What will happen when three new students arrive? Specially when they'll be more famous than Harry Potter.

Percy Jackson has just finished the war with Gaea and he won. But, in order to kill the earth goddess, there had to be sacrifices, and those were the lives of the most precious people in his life. He couldn't take it anymore, he just wanted to end his life and join his friends in Elysium. When the Olympians know of this, they decide to send him to a special school along with his two cousins Thalia Grace and Nico Di Angelo. They think that it'll help them in getting over the deaths and help a trio to 'get down to earth'. What will happen? Will they recover and be happy again? Or will they stay depressed and blow up the school like they always do

This is my first story, so I really hope it's not too bad. I'm sorry for the grammar mistakes, it's not really my strong point😅. Tank uzz and byeee😊.
