The Axe of Eternity is a massive weapon wielded by the entity known only as Millennium. It was originally created by the Great Beings, though it was stolen by Millennium during his exile. It was originally forged from Exsidian, though Millennium has added additional layers of Protosteel to make it extra durable, resistant, and effective. It is used primarily to focus Millennium's Elemental Powers over Time. The blade itself has the ability to cast powerful illusions that appear almost real.
