In the game, it is played throughout the Underworld area. It was included on the Soul Reaver 2 Promotional Soundtrack, as well as the game disc.
The Underworld track starts playing when Raziel shifts to the material realm for the first time. Until then, its spectral version plays in the whole Underworld area. It also plays in many other areas such as on the road to the Abyss and in the northern vastes. The track has many variations besides the standard five - it has an additional wilderness variety which plays only in front of the Sanctuary of the Clans.
The track returned in a more ominous form in Soul Reaver 2, where it plays only in the caverns, where the Elder God dwells.
