The original Balance Guardian was an ancient Vampire, and the first Guardian of the Pillar of Balance, summoned to serve when the Pillars of Nosgoth were raised. The Guardian was alluded to in Soul Reaver 2 and Legacy of Kain: Defiance, but not explicitly seen.
Amy Hennig and Carol Wolf's script for Defiance's The Transformation of the Reaver scene directed that "we see first Ariel manifest, transformed into her perfect state when she is summoned, and then one spirit after another join and unite with her. The player may notice, we do not see Kain's spirit."[Defiance/Cut content] However, only Ariel's spirit is distinguishable in the final product, with the other Balance Guardians manifesting as multicolored soul energy.[Defiance/12] The predecessor Balance Guardians do appear in some fashion however, with the textures of the Spirit Reaver made up of a number of faces - presumably representing the previous guardians.[Defiance]
