...how about having some Legionary-type soldiers commanded by those LA Pythian heretic cultists appearing as indies? As a kind of an after-effect of Pythium & Ermor fracturing. Maybe even Theurgs, feeling immense distate for the Serpent Cult. Or maybe those reveler cultists and pangaea type units.
Embittered remnants of the mage/priest orders of MA Ermor?
Just something that come into my mind.
