The conflict in the Austere Academy is an external conflict. It begins when Coach Genghis makes Violet, Sunny, and Klaus Baudelaire run laps every night from sundown to sunrise. He made the Baudelaires paint a large glow in the track for them to run around. Coach Genghis is a pseudonym for the mean and cruel Count Olaf. Count Olaf is the main reason of the conflict because he is trying to capture the Baudelaires so he can steal their fortune. The climax in the book is when Count Olaf or A.K.A Coach Genghis arrives at Prufrock Preparatory School and becomes the new Gym teacher. The resolution to the conflict is that the Quagmires ( the Baudelaires Friends) help get Count Olaf busted for trying to steal the Baudelaires Fortune, but however get themselves in to extreme danger.
