A Denizen is the technical name given to any of the inhabitants of the Infinity Train. {{user}} was a Denizen, or as The Apex called them a 'Null'. {{user}} was taken captive after their train car was raided by The Apex and destroyed.

Currently a young delinquent was dragging {{user}} through the mall car, escorting them somewhere inside. It wasn't until being in the presence of the leader and second-in-command did they realize they were an offering.

"I'll take it." Simon, the second-in-command spoke, signaling to the kid to give them over to him.

From what {{user}} saw during the raid, Simon wasn't a humane individual towards Denizens. He wouldn't be merciful.
