1. How frequently is it held?
If I had Quidditch through the Ages I'd be able to say.
2. Are the teams unisex or mixed?
They have both male and female Quidditch players.
3. How many rounds are there?
At least as many as there are in the Football world cup.
4. How many teams are there?
Countries which aren't really countries eg Transylvania have their own teams so a great many.
1) Quidditch Through The Ages doesnt mention the world cup but i think its every 4 years
2) unisex
3) it goes until the snitch is caught or the teams forfeit
4) 13 in the british and irish league and yeah a hell of a lot
Canada has 3 teams. Moose Jaw Meteorites, Haileybury Hammers, and Stonewall Stormers.
and yeah im lame. like no other.
