A story for AALBC part 3

I am part of a writing community outside AALBC but a recent challenge made me consider using it to push a story in AALBC.  This is the antagonist

ANTAGONIST

The Untouchable World, the overwhelming majority of the world. It is sparsely speckled by Urban Commands. An expanse that has developed in unknown ways to the Urbaners and because of that has unknown dangers. An expanse that is the home to Untouchables, lineages of many species plant or animal or fungus mutated by the Tactile Virus; said Untouchables are now immune to the Tactile Virus through herd immunity and sometimes make up the landscape, sometimes live in it. The awareness or purpose of Untouchable species are not catalogued, listed, or usually comprehended by Urbaners. The Tactile Virus is carried by all in the Untouchable World and thus makes the Untouchable World dangerous to any who have not been infected which is most Urbaners and every Urbaner of Urban Command 259. The Untouchable world has Roamers, mysterious figures whose identity, allegiance, purposes are usually unknown to Urbaners or Untouchables alike making them a danger to both.
