Liberation of "Hogwarts": Gorbina and Burks' Secret Store

I'm a seasoned dark-fighter, I know what I'm talking about. Dark wizards have already penetrated the school. And if they managed to do it, it means they miraculously neutralized the headmaster, one of the most powerful wizards in the country. If my information is correct, there is a way to penetrate the school, bypassing all protective charms and spells. I'm sure the Death Eaters have used it. Yes, it's a vanishing cabinet. One is located in the headmaster's office, the other - here, in Borgin and Burkes, a shop for dark wizards. Your task is to infiltrate the store, activate the vanishing cabinet and get to Hogwarts. I'm sure you will find a way to clear it of the Death Eaters and free the school.
