"the fourteen players rose towards the leaden sky"

Quidditch is a game invented by J.K. Rowling involving two teams, with 7 players each, all flying on broomsticks. Quidditch is played over an oval field, with three elevated goals at each end.

It is played with four different balls: the Quaffle, 2 Bludgers and the Golden Snitch. Each team is composed of three Chasers who pass the Quaffle amongst themselves and attempt to score goals; one Keeper who tries to prevent this from happening; two Beaters, armed with a wooden bat, whose main aim is to protect their teammates from the two roving Bludgers and at the same time send these two iron balls in the direction of their opponents; and the Seeker, a very important player, who ends the game as soon as he manages to catch the Golden Snitch.

The winning team is the one with the most points at the end of the game. Each goal is worth 10 points, and if the Seeker catches the Snitch he adds another 150 points to his team’s score.
