Item from harry-potter-prisoner-of-azkaban by
The finest racing broomstick in the world, sent to Harry anonymously on Christmas morning by Sirius Black — confiscated, tested, cleared of curses, and then used to win the Quidditch Cup.
The Firebolt arrives on Christmas morning without a card, and it immediately splits the trio. Harry and Ron are ecstatic. Hermione reports it to McGonagall because a convicted murderer is trying to kill Harry and an anonymous, top-of-the-line broomstick is exactly what a trap looks like. McGonagall agrees and confiscates it for jinx testing. Harry and Ron don't speak to Hermione for weeks. The broom is eventually returned, curse-free, and Harry uses it to win the Quidditch Cup — catching the Snitch against Slytherin in what Oliver Wood considers the greatest moment of his life. The Firebolt was sent by Sirius, who bought it via owl-order using Crookshanks to carry the form. It was not a murder weapon. It was a godfather trying, for the first time, to give his godson something good. The broom is the emotional bridge between Sirius the terrifying fugitive and Sirius the family Harry never had.
A sleek broomstick with a polished ash handle and perfectly aligned birch twigs that taper aerodynamically. The handle inscription reads 'Firebolt' in gold lettering. It hovers at exactly the right height for mounting. Acceleration from zero to one hundred and fifty miles per hour in ten seconds. International Quidditch teams use it as their standard broom.
