"Anybody wishing to submit themselves as champion must write their name and school clearly upon a slip of parchment and drop it into the goblet," said Dumbledore. "Aspiring champions have twenty-four hours in which to put their names forward. Tomorrow night, Halloween, the goblet will return the names of the three it has judged most worthy to represent their schools. The goblet will be placed in the entrance hall tonight, where it will be freely accessible to all those wishing to compete.
