A red-gold glow burst suddenly across the enchanted sky above them as an edge of dazzling sun appeared over the sill of the nearest window. The light hit both of their faces at the same time, so that Voldemort's was suddenly a flaming blur. Harry heard the high voice shriek as he too yelled his best hope to the heavens, pointing Draco's wand:Avada Kedavra!Expelliarmus!The bang was like a cannon blast, and the golden flames that erupted between them, at the dead center of the circle they had been treading, marked the point where the spells collided. Harry saw Voldemort's green jet meet his own spell, saw the Elder Wand fly high, dark against the sunrise, spinning across the enchanted ceiling, spinning through the air toward the master it would not kill, who had come to take full possession of it at last.
