Macey’s dormmate frequently had loud music playing at night. She’d asked him to keep it down, and had complained to the dorm supervisor, but nothing made a difference.
So she decided to use magic.
First she cursed his speakers, but he simply bought new ones. Then she caused a power outage in his room, but that was fixed by the dorm’s maintenance team.
After several weeks, Macey perfected a spell that caused an unholy wailing to fill her dormmate’s room whenever the music was too loud. Silence soon filled the dorm, and Macey was finally able to get some sleep.
