Agnus was a content boy. Days went fast for him. He had a 7 year old sister who was set on annoying him. He also had a mother and father. His father was the wizard, but Agnus never knew this. His mother had a tendency to snap at people when she was stressed. He woke up at 5:30 am every day to go to school.

He was 9 years old. It happened when Agnus was writing his book. His sister was annoying him again, and his parents weren't doing anything. He couldn't focus, so he got very angry and stressed. Then his sister suddenly went silent. Agnus accepted this as luck. This was actually accidental magic.
