Thomas was in the laundry room of his apartment building when he realized that he felt an odd breeze. Some work crews had been down here moving some water and HVAC piping around, but it seemed that something wasn't sealed up correctly. He felt around with his hand, and discovered the breeze was coming from an completely different area. He moved aside a thick partition and discovered a concrete passageway leading away from the laundry room. He followed the passageway for several hundred feet, going down deeper into the ground, and generally east of his building.

As he traveled, he brought out his phone and used the light on it to illuminate the passageway. At some point, he saw a puddle of dark liquid--oil? Ink? He poked at it a bit with a finger, but it wasn't something that he could identify, thought he did get a static electrical spark off the stuff.

He continued to move down the corridor, but, now he saw lights ahead, seeming to come on as he got closer. Finally, he passed through a doorway, which then closed behind him! He discovered a button that opened the doors, so he could exit if he needed to do so.

But, turning around, he saw he was in some sort of industrial lab. It was full of workbenches and tanks of fluid, plus tubes and piping that seemed to connect to the tanks.
