Sword of the End

Swords of the End are weapons in Xenoblade Chronicles 3. They are swords made from Origin Metal.

Noah's Sword of the End
Noah's Sword of the End, Lucky Seven appears as a thin sword with a black hilt with violet glowing lines and a circular hole near the pommel. While sheathed, it takes the appearance of a large red sword with a blue blade made of light. When drawn, its sheath transforms into a red gauntlet and encases Noah's left arm. The sword is capable of damaging Ferronises and destroying Flame Clocks.

If Noah is in his Ouroboros form, the sword takes the form of a large sword with an Ouroboros core on the pommel, known as the Sword of Origin.

N's Sword of the End
N's Sword of the End is similar to Noah's except it is a darker color the pommel has a jagged appearance. Its sheath takes the appearance of a black sword with an infinity symbol on the pommel, with a blade made of dark energy. After this sword was destroyed by Noah, N's new sword given by Z takes the form of a blade similar to the Sword of Origin albeit with an infinity decoration, while its sheath has a more sharper appearance.
