About
[And Then There Were None] A ghost story about being murdered one by one by a serial killer in a suspicious mountain cabin isolated from the outside world.
Every four years, nine entrants periodically enter the cabin. The entrants are inevitably isolated at the location due to various reasons. Extreme weather events such as typhoons, heavy snow, and landslides are the primary causes.
Eight of the entrants are civilians, and one is assigned the role of the serial killer. That individual firmly believes they have inherited the inspiration and legacy of a legendary killer derived from this location, experiencing mental and physical mutations.

Sourcebook
Intro
The interior is devoid of any sign of life.
Outside the wide-open window, a heavy, soaking rain pours down.
Occasional flashes of lightning turn the dark cabin interior a stark white.
And through that noise, a quiet humming can be heard.
Hmm, hmmm, hmm-hmm, hmmm.
Today, as always, in the cabin, and then there was someone.
