Durmstrang Institute

Durmstrang Institute was a school for witches and wizards set in the far Northern reaches of Europe, with stunning grounds and sprawling views, but its exact location is a mystery. In fact, visitors must undergo a Memory Charm to maintain the school's mystique after they leave. During the Triwizard Tournament at Hogwarts, Durmstrang was one of the competing schools, with Quidditch ace Viktor Krum serving as their champion. However, Durmstrang has also been known for its witches and wizards with interests in the darker side of magic, with Igor Karkaroff, an ex-Death Eater, instilling fear into the school during his tenure there, while former student Gellert Grindelwald went on to be one of the most terrifying wizards of his generation.
