I've been toying with the idea of making a campaign's antagonist an HMHVV infected technomancer (AKA techno-ghoul). Is there anything in the various sourcebooks or official fluff that describes this in-detail? I'm looking to both avoid conflicting with any precedent, and to steal any good ideas.
Since the HMHVV grants astral-sensitivity, I wanted to extend that, and have a bad-guy who could create technology-spirits - some sort of unholy union between a sprite and a spirit, something akin to a toxic or insect spirit, able to affect the matrix, and physically manifest itself within piles of discarded technology.
