Sword of the End

Swords of the End, alternately Swords of Origin, refers to several weapons in Xenoblade Chronicles 3. They are swords made from Origin Metal.

Noah's Sword of the End
Noah's Sword of the End, named Lucky Seven by Riku, appears as a thin sword, featuring a black hilt with violet glowing lines and a circular hole above the grip. When sheathed, it takes the appearance of a large red sword with a blue blade made of light, known as the Veiled Sword or Truthsinger. 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. It vibrates when in the presence of Moebius.

If Noah is in his Ouroboros form, he may draw a similar large sword with an Ouroboros core above the grip. This sword can also destroy Flame Clocks. Riku calls this sword Lucky Seven as well, and states that its nature is the same as that of the regularly-sized sword.

N's Sword of the End
N's Sword of the End is similar to Noah's except that it is a darker color, and the guard has a jagged appearance. Its sheath takes the appearance of a black sword with an infinity symbol above the grip, 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 identical to Noah's Ouroboros' sword, albeit with an infinity decoration in place of the Ouroboros core. This sword's sheath has a sharper appearance.

Future Redeemed
N uses his Sword of the End to kill his son, Ghondor, when the latter tries to protect his granddaughter, Na'el during the City's fall. N later uses it against an Alpha-possessed Na'el and Matthew at, much to Rex's shock. N once again uses his Sword of the End to battle party at the in an attempt to thwart the party's advance to Origin. During the final battle against Alpha, N allows Matthew to use the sword's power in conjunction with his gauntlets to unleash the true power of Ouroboros, allowing the party to Interlink and finish off Alpha.

Lore

 * According to Riku, Lucky Seven was forged by "seven legendary swordsmithpon"; according to Nia, it was produced via the heart of the Queen of Keves resonating with Origin. The sword was entrusted to Riku by his Masterpon some time before the events of Future Redeemed.

Trivia

 * "Sword of the End" and "Sword of Origin" are each used to refer to multiple swords, despite characters referring to "the Sword of the End/Origin".
 * Nia and Melia state that Noah carries and uses the power of "the Sword of the End" (although it is unclear whether this refers to only one or both versions of Lucky Seven). Meanwhile, Z calls N the wielder of the Sword of the End.
 * N calls the sword from Noah's Ouroboros "the Sword of Origin", while X states that N is the wielder of the Sword of Origin. The cutscene in which this dialogue occurs is called The Sword of the End, although this name is not used in the cutscene.
 * Dialogue and camerawork in Future Redeemed suggests that Logos (or its remains) are contained within N's Sword of the End.
 * There was a model error in the cutscene where Z convinces N to take up the Sword of the End in Chapter 7; it erroneously displayed N's original Sword of the End. This was later fixed in the Ver. 1.2.0 patch.
