Sentry eyes

Sentry Eyes, also known as Sentries, were featured in Soul Reaver 2. They were security devices, presumably built by the Ancient Vampires, which required the Dark Reaver to bypass.

Sentries resembled large wall-mounted eyes. When disturbed by Raziel, (or indeed other creatures) Sentires would produce a brief rain of sparkles before unleashing a fatal blast that was powerful enough to disintegrate Raziel's Material manifestation.

Raziel first encountered a Sentry in the Light Forge in Soul Reaver 2, when he witnessed it destroying a Thrall. Sentry Eyes could be 'blinded' by the Reaver Bolts of the Dark Reaver, which would cause the eyes to roll back allowing Raziel to temporarily pass 'unobserved'.

Sentry Eyes were not seen in further games
