The hallowed Scabbard of Excalibur. The embodiment of Utopia. Its connection to the heart of the world, Avalon, grants its wielder regenerative immortality simply by carrying it. And when Mystical Energy is supplied and its true name is called it becomes the ultimate shield, by overwriting the rules of the world around you temporarily to become like the utopia it is connected to, a world where the concept of harm and hurt does not exist. Thus it can block even the likes of true magics from harming its wielder.
