Unbreakable

The Unbreakable is, as the name implies, is an unbreakable weapon, forged from a variety of metals, making it incredibly durable but also extremely heavy. It takes no small amount of training to wield this weapon, and more so to swing it properly. Its width also allows it to be used as an equally impenetrable shield. Though it may suffer damage and chips, it will eventually mend itself by absorbing other metals, from weapons and armor it struck, but one would have to wonder, if a blade is fixed from various other blades and materials, is it still the same sword?

The greatsword has been passed down from user to user, and it has only gotten stronger over the ages. It seems to absorb the properties of those it slays; it has been documented that unbreakable could slay Unfamiliars with ease. The Unbreakable seems to be thousands of years old, created during a time now lost to history. It wasn't treated as an actual weapon until the Chosen Knight of Patience, Alexandra trained persistently to wield it. She was the first wielder, but she lost it a few centuries ago after using it to slay Genghis-Khan, leaving it to end up in the hands of other stubborn warriors throughout time.
