Z - Harbinger of the End

Z - Harbinger of the End is Disc 8, Track 6 on the Xenoblade Chronicles 3 Original Soundtrack and Disc 19, Track 6 on the Xenoblade Chronicles Original Soundtrack Trinity Box.

It shares many melodies with Grand Theater of Life. It also uses a motif from, specifically Moebius 3, at 1:22.

It plays when Z tells the party his reasons for maintaining the endless war before they fight in. It also plays in Future Redeemed when Alpha tries to take Matthew's soul between the two phases of his fight in.
