Nascent Requiem

"Nascent Requiem" is the final boss theme of Final Fantasy XIII. It was composed by Masashi Hamauzu.

Final Fantasy XIII
As forementioned, "Nascent Requiem" is the theme that plays in the final battle against Orphan.

Unlike "Born Anew" or "Fighting Fate", "Nascent Requiem" has no lyrics, and is much more fast-paced, perhaps because of the battle's forced speed, due to Orphan's Doom spell. It contains the altered form of the summary motif (starting at 2:21) of "Vanille's Theme", particularly at 0:50 to 1:13 and 3:41 till the end of the loop.

"Nascent Requiem" is the nineteenth track of the fourth disc of the game's Original Soundtrack.

Masashi Hamauzu included a prototype of "Nascent Requiem", named "Last Battle Prototype+", in Final Fantasy XIII: Original Soundtrack PLUS

Final Fantasy XIII-2
"Nascent Requiem" plays during the Beginner's Primer summary for Chapter 12.

Dissidia 012 Final Fantasy
