The locator showed that Kent Henry had indeed gone to the underground black market and was lying low. Besides the communicator, Jonathan had also sent a tiny spy spider into Kent Henry's clothes as an extra precaution.
After some time, the spy spider in the spiral tunnel sent back feedback. The branching tunnels were interconnected with the city's sewer and underground rail lines, forming an intricate network like a vast anthill.
With the limited number of spiders, only a small portion of the underground passages had been explored. There were many more yet to be detected. The explored tunnels were either far from the surface or directly repurposed from existing sewers and underground rail lines. This clever design helped the secret cult avoid detection by the federal government during maintenance checks.
