Theatre

The Theater is located on the Spin-a-yarn Square, in the center of the Marrow. It is apparently the home of Mark Immortell.

Description
The theater puts on several types of performance, including puppet shows. According to Mark, these shows are performed on a regular basis. After midnight of each day, the player may go to the Theater to view an interpretive performance by the Masks.

Usually, these performances begin with a chorus arguing different views and ideologies pertaining to the events of the day; following this, the Masks display a tableau representing the current conflict in the story.

According to Mark, children are not permitted to view these performances.

"An alien thing, like a flying saucer that’s descended upon the town. Through the “theatre of death”, the player enters the meta level—quite literally, since it’s where the game loads from. Like an actor whose character has just died, the player exits through the Theatre doors and back into the world—invulnerable in his or her own way, belonging to the world of death. However, the Theatre also becomes the point where the town’s clinging to life is at its most desperate: it’s where the hospital is set up."

The Theater is accessible upon Artemy's arrival in town. Entering it during the day will show that it is empty, save for Mark Immortell being present on the stage. The player is able to speak with him, though it is unclear if this is the same Mark from the player death interactions, or if there is a difference at all between the two.

After Day 3, the Theater is used as a hospital (and later morgue) for victims of The Plague. Artemy is able to work in the hospital for a reputation bonus and physical reward through cash and resources. Stakh and Bachelor can sometimes be found here during the day.
