Theo roared above him, casting out a protego around Draco’s long spindly form. Luna joined him and together with their soulbond the shield held true - blocking any oncoming spells aimed in their direction. Hermione cast a series of chains from her wand, wrapping around the legs of three death eaters who had made it past Lucius’s fire. They fell to their knees and simultaneously were burned alive by Draco. The fire ball he used to penetrate each of their chests hovered in the air ready for another target. Each time someone broke through Lucius’s barrier they were destroyed instantly by the fiendfyre. Draco beat his wings loudly in the cavern and let out his own cry, trying to tell his father without words how grateful he was to have this opportunity at a life - with his soulbond and his fathers blessing.
