Maleficium Imperium discussion

The Hogwarts Gatehouse is located in a short distance from the Boathouse. During the Battle of Hogwarts, the gatehouse was guarded by a giant, one of the Death Eater allies. Harry Potter, Ron Weasley and Hermione Granger passed through the gatehouse on their way to find and kill Nagini, which at the time was with Lord Voldemort and Severus Snape in the Shrieking Shack.
