"The steps are covered in arcane chalk symbols. Don't worry, they are likely benign. The Capulets are known for making their fellow students feel welcome, and any rumors of magical experiments are not only unfounded but hurtful. We assure you that almost all of the passerby [sic] they've captured are still alive, in a fashion, and we expect that you'll be treated just as well despite your shortcomings."

Pretty, popular, and meaner than mean, the Capulets used psychology to control their classmates and punish their enemies. Left to their own devices, their interests have grown more devious.  Please disregard the green flames that follow them from room to room.
