Heat Changing Room of Requirement Mug
"It is a room that a person can only enter when they have real need of it. Sometimes it is there, and sometimes it is not, but when it appears, it is always equipped for the seeker's needs."
It might seem like something is missing from the halls of Hogwarts, but don’t worry, something will appear when you are in real need of it. You need only to add a hot beverage to your mug! And not everyone will be able to see what’s missing from the edge of the Forbidden Forest but those who can, do not fear. These creatures are not an omen of death but a sign the beholder has gained an emotional understanding of what death means. Now that is some heavy stuff!
