Devilfish:Ashton Catacombs

You may be asking yourself why a PNW city probably barely 150 years old has a massive catacomb system branching throughout the city frequently crisscrossing the metro system. The answer is they are not literal catacombs where the dead were buried, but many different sewer lines, access tunnels, rarely used rail lines, closed underground malls, and other rarely traveled underground passage ways that have been widened and connected by productive Capes over the last 35 years. They are nicknamed the Catacombs for ease of reference and because it sounds cool.
