The Time Reaver enhancement was the fifth and final Reaver enhancement gained by Kain in Defiance. Kain found the enhancement in Chapter 9 when exploring the Vampire Citadel, he found his way to the Light Forge and discovered the Time Fragment of the Balance Emblem upgrading its power. With the Balance Emblem complete Kain was able to enter the inner sanctum of the Vampire Citadel.[Defiance][Defiance/9].
The Time enhancement is also associated with Time and the Pillar of Time and it is named the "Time Pillar" in the Debug Menu. Strangely it is referred to as "reaver_god" in game files[Defiance].
The Time Fragment has presumably resided in the Vampire Citadel since ancient times, however like the other Balance Emblem fragments, it is possible that Moebius had a hand in its placement.
The Time fragment was the last fragment of the Balance Emblem for Kain to receive, it did increased damage when fully charged and worked like his Slow TimeBattle Artifact. (Enemies move a fourth of their speed).
