It’s the Fulton Football Club championships

All the best teams in the league are coming together to determine the winner of the Zelder Trophy. The reigning champions, The Serenity Heights Sirens, are back to defend their title, but they have some stiff competition.

Who broke it? Why? And if the thief was simply trying to steal it, why leave it behind?
