They moved into a tomb called the Research Institute.
They called themselves the tomb dwellers.
The tomb dwellers' jobs were crudely divided into several categories.
Researchers were responsible for analyzing samples, hunters for donning isolation suits and collecting samples outdoors, caregivers trying to sustain life and mobility of patients, and laborers handling logistics.
Every day, every hour, someone would be infected by the S Bacteria, which infiltrated their isolation suits by any means necessary.
Those hunters would then shed their isolation suits and travel light.
These people were called walkers.
Others from different professions would put on isolation suits, leave the institute, then take off their battle robes and become walkers too.
Walkers would either travel on foot or drive across the Australian Continent, monitoring every potential newly born infection carrier.
