The One Who is Torn Apart

The One Who is Torn Apart (called Torn on the Revival disc) is Disc 1, Track 13 on the Xenogears Original Soundtrack and track 39 on the Xenogears Original Soundtrack Revival Disc -the first and the last-.

It plays as the battle music against Id in Zeboim, as well as in the immediately prior and subsequent cutscenes. In addition, it plays during the following cutscenes:
 * Fei tells Citan how Grahf appeared in Lahan Village, and Citan speaks with Cain about the time of the Gospel.
 * Id appears before Bart and Ramsus in the Aveh desert.
 * Id raises the Yggdrasil above him before throwing it at Bart.
 * Citan speaks with Id in Solaris (flashback2).
 * Fei sees images of other people after being frozen in carbonite.
 * Miang encourages Lacan to seek the Zohar (flashback).
 * Citan narrates how Id went in search of the Zohar after breaking through his carbonite encasing.
 * Inside Fei's head, Id tells Fei that the latter is a fake, subordinate persona.
 * Fei momentarily accepts being inside Id's head until he's reminded of Elly.
 * Id shows Fei his memories of Fei's childhood.
 * Id returns to Fei the memories of the past Contacts.

Finally, it plays as the area theme in Nortune after Deus awakens.
