The Battle of the Astronomy Tower (2020)

On 26 June 2020, Death Eaters broke in to Hogwarts School of Witchcraft and Wizardry by posing as members of the CDC inspecting the grounds as part of the response to the Coronavirus Pandemic. The reason of the break-in is to target Dumbledore for protecting Christopher and two muggle-borns. After Dumbledore refused to accept Malfoy's request to disband the relationship, Malfoy shot a killing curse at Dumbledore, killing him.
