Raising of the lieutenants

The Raising of the Lieutenants was an event mentioned in Legacy of Kain: Soul Reaver.

History
Five hundred years after the collapse of the Pillars (and one hundred years after the destruction of the Hylden Gate in the fourth timeline), Kain finally discovered a way to raise vampires himself: by snaring a soul out of the Spectral Realm and using it to reanimate a corpse, a method most likely based off of his own resurrection as a vampire by Mortanius.

In an act of irony and blasphemy, Kain broke into the Tomb of the Sarafan and breathed portions of his soul into the six sanctified Sarafan Inquisitors (in order, Raziel, Turel, Dumah, Rahab, Zephon, and Melchiah), reanimating them as vampires with no memories of their human lives.
