Bond of blood charm

The bond of blood charm is a charm that can be cast after a Sacrificial Protection is made. The victim must be related to the sacrificed person to work properly and the victim can then be protected from a murderer while he or she can still call the sacrificed person's blood-relative's living quarters 'home'.

This powerful charm was cast by Albus Dumbledore on Harry Potter in 1981 after Lily Potter cast herself between Harry and the Darkest Wizard of all time and 'Chief Death Eater' Lord Voldemort when the latter tried to kill Harry. Lily refused to step aside and was brutally murdered which made the Sacrificial Protection and allowed this charm to be cast. The charm was ultimately sealed when Lily's blood-relative and sister Petunia Dursley took Harry inside her house. This prevented Voldemort, and actually anybody else, from hurting Harry until the day he turned seventeen or when he no longer called the house at Privet Drive his home.
