Arcadia

In the year 2014, a new magical sport was created in magical Britain, it is called Arcadia. It is a sport were wizards use golem like creatures known as Avatars to fight each by giving them commands. This follows the story of Galahad Xavier Olivander, a 25-year-old who is the creator of Arcadia. Widely considered the best, Gal was captain of the team, "Excelsior", holding the title of the 'Dragon King' with his Avatar Rayquaza. He is forced to resign from the team, giving up one of the strongest Avatars and leave the competitive scene due to his unwillingness to take part in any marketing to profit the team. Gal ends up finding work called Arcadia Sports in Diagon Alley which sells from Attack Cards, Avatars and robes from favorite teams. This is where he meets Albus Potter, the son of Harry Potter and an employee of the shop who happens to be a huge fan of Gal's alias 'Xavier King', his former team and Rayquaza. While awaiting his return to the competitive scene, Gal continues playing the game, building a character from scratch and pursuing the championship.

In this story the events of Harry Potter and the Cursed Child never happened. Albus, Scorpius and Rose were best friends like the new golden trio even if Albus and Scorpius were in Slytherin and Rose was in Gryffindor.
