Following a near-fatal bus accident, which the characters survive unscathed, they begin to notice that they are being followed by gaunt cadaverous beings with ashen skin and eyes the color of frozen meat dressed in drab gray Victorian suits; their faces are locked in a deathlike grin associated with rigor mortis.
When the characters are together, these beings stay their distant, watching the characters with their cold unblinking dead eyes. Once the characters break up or go their own way they attack that individual investigator working their way until they have killed everyone who survived the encounter.
1 The beings are apparitions of accident victims on that stretch of land. They are haunting the investigators to see if they can get released into the other side. However, after several days of being ignored, they no longer seek release but instead seek to make the investigators one of them.
2 The investigators escaped death – they should have died that night. The cadaverous beings are minions of the grim reaper, sent to kill the investigators and uphold the balance of nature.
3 The investigators did not escape the accident unhurt; they are all in a local Hospital in comas. The beings that they are seeing are the warped form of their visiting friends and loved ones.
