A story for AALBC part 1

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 setting

SETTING
Long after the fall of the Constellamperor, the last ruler of the whole world, who legend says began the Tactile Virus plague. The planet is broken up into two things.
Second , The Urban Commands, self isolating city states, born from a heritage of surviving the ever mutating virus with walls plus fire plus suits. They are self sufficient in purpose, socialist in racial ranking , militaristic in communal structure,  merit based in human relationship. Consummation has a space, Leaders have a space, everywhere else are barracks. All children, Initiates, are raised together. All Initiates get a rearing to gain at least one Utility. A communal structure maintained out of successful habit. 
First, The Untouchable World, the lush fertile lands or seas or skies the Urban Commands are dotted in. Where few are mysterious figures who are only known through legends or myths or gossip to Urbaners or Untouchables. Where most are Untouchables, the descendants of species infected by the virus who gained herd immunity but can still spread it with a touch. Most Untouchables live unknown to the Urbaners. A few Untouchables from plants to insects live just beyond the walls of Urban Commands are flow seasonally to said walls. 
In this landscape exist Urban Command 259 whose comrades have to maintain their growing city, continue their way of life, defend from the seasonal threats in the Untouchable World.
