a Spartan Neo-Heretic, one of several hundred Thousand who have recently deserted from Spartan units without warning.
All of these men seem to be coordinating on Planet Tau Volaria, deep in the Core of Ancerious.....
the neo-heretics are Spartan personnel corrupted by the energies of the Phasic Vortex, a swirling abyss of dark energies originating outside the core of Ancerious. these men have forsaken the Spartan way, their minds possessed by the foul energies that exist inside the vortex. all of Sparta's ability, with none of their honor....a serious foe indeed.
