Chicago Underground
Hidden under the windy city is a 62-mile grid of abandoned freight tunnels once considered an engineering masterwork.
Although the impressive grid connects all major railroad freight houses and many commercial establishments in downtown Chicago, few people ever saw this system from construction in 1899 to its abandonment in 1959.
The Chicago Underground is home to the Nosferatu of Chicago, and they had a guiding hand in it's construction. Khalid's haven is down here. When the tunnels flooded in 1991, he was lucky to not be there. He has since searched for the culprit.
