This chair apparently has trouble staying in the same place.
c.1976 Nate Featherwell, aspiring ventriloquist, had big dreams but not much talent. He spent his life savings on a charm from a voodoo priestess. When used correctly the spell would bring wood to life. Nate hoped to use it to charm his dummy, Smuggy, but accidentally worked his spell on the chair he sat on instead. The chair, alive but ignored, grew jealous of the attention Featherwell lavished on the inanimate Smuggy, and did away with them both in a rage-fueled wood chipper "accident." The chair slipped away unnoticed and remains at large to this day.
Where to Find It
In the Field: After the Rookie hits the third portal on the way out, the paper constructs appear and disappear, in the small room that is upside down, the PKE meter will sound in the further left hand side of the room. The chair is on the ceiling.
At the Firehouse: First floor, at the end of the wooden crate near the TV.
Featherwell's Stalking Chair is now on display at Ray's Occult Books.
