If you did a Google Map search for Dr X’s school, you’ll see the Canadian heritage site Hatley Castle, popping up on your phone. It is a mini castle, which is a part of the Hatley Park National Historic and also houses a functioning university. In fact, the castle was once used in the popular Marvel show Arrow.

The school’s real address is said to be 1407 Graymalkin Lane, in Westchester, New York. Graymalkins was a clan, with a dark connection to the birth of the mutant species. In the comics Manifest Destiny, Beast discovers an ancient mutant creature which he claims is over 2000 years old. It just happens to be the son of a Charles Graymalkin, Jonas, who was buried alive by his father, when he found out his son was a homosexual. The school’s mansion originally belongs to their family.
