Dark Marker

The Dark Marker is a major catalyst in chapters 1 and 2 of The Dark Marker. It is a supernatural object owned by the Power which resembles a plain black marker and has the ability to cut through any solid surface it is used directly upon. The Power guards the Dark Marker fiercely, and while it does not consider protecting the marker important, the Power will vengefully destroy anyone who tries to steal or use the marker, unless they relinquish it.

The Dark Marker: Chapter 1
Quentin steals the Dark Marker from the Power, recognizes that the Power is after him, and tries to avoid punishment by giving the marker to an unnamed coworker. The coworker either chooses to destroy the marker, give it back to the power, destroying Quentin, or chooses to keep the marker, resulting in their own death. Eventually, after the events of the game, a body is found in the building (either the unnamed coworker's or Quentin's), and Fizzysoft is shut down. Canonically, the Dark Marker survives and is taken out of the factory, to continue its spree internationally.

The Dark Marker: Chapter 2
An unnamed teenager is on vacation with their mother in the coastal town of Kudasai, Manboni. They find a rock washed up on the beach, which came from Spain across the ocean, and open it to find a Dark Marker, which is actually the Second Dark Marker. The teenager is then hunted by the Power in various forms, and can choose to break into their mother's cellar to find the original Dark Marker, old and dilapidated.
