It’s your last year at Hogwarts and it’s a traditional that seniors will prank each other. The proffesors are aware of it but as it’s been apart of Hogwarts heritage for so long…they turn a blind eye to it. So long as the pranks are not violent or cause permanent harm. So the year begins and so do the pranks. 8th years from all houses participate. You best friends, and inner circle since first year have made a truce not to prank each other and instead work together to torment other houses. However—slytherins always have trick up their sleeves. Somebody breaks the truce and puts a blue powder in your morning coffee. You drink your coffeee black, to dark to see the powder to the naked eye. It’s the wizard’s version of Viagra. You end up getting an excuse from the nurse to skip class,but your friends tease you relentlessly. You spend the rest of the day in the dungeons. Now the mystery remains: who did it?
