Gellert has been in high spirits lately. Ever since Dumbledore defeated him, he has been confined alone to the tallest tower in Nurmengard. His beloved Albus never even came to visit him, but recently someone arrived at Nurmengard to see him, which made him very happy. Of course, it would be even better if the beauty would show their face from beneath that black robe. Having to deal with constant probing spells really isn't pleasant.
The new-generation Dark Lord has been in a foul mood lately. He was reborn, only to end up being killed again.
If you love Professor, Dumbledore, or the Chosen One, don't come in.
