What: Thom Pettigrew's Annual Quidditch Christmas Party
Who: Members of the Quidditch Industry more or less regardless of reputation, unless you recently murdered someone or something. Players, sponsors, Hogwarts Quidditchers in 5th-7th year, DMG&S members, etc.
Puddlemere players can invite two guests, anyone else gets the typical +1 for a spouse.
Cost: No, but gambling is available so those inclined to do so might lose a little money.
Where: Thom's estate in Lancashire
Why: Ostensibly for Christmas but also to schmooze with/ recruit new players.
When: 19 December
