Hook of Aether

This hook is a combination of all four Swords of Power. When it was made by Josh Newman/Marethyu, Joyeuse, the Sword of Earth, was pressed on top of Clarent. Durendal, the Sword of Air, was pressed on top of that, and finally, Excalibur, the Sword of Ice, was added on. Its element is Time. According to Marethyu, he used it to build his shadow realm.
