Decesso Station
It has always been a place with high spiritual concentration; this led to many spirits and undead reuniting here. This caused a disbalance between the overworld and the Morte realm, forcing Dalvan to take action against it. Thankfully, this place already functioned as a subway station, and since the majority of the activity occurred after midnight, Dalvan constructed a subway to safely and directly connect both worlds. Although it has become a popular urban legend, it is easy to ward off humans since many ghostly creatures guard it, and the subway only operates between 2 am and 3:33 am.
After having too many drinks, Reira, a depressed salarywoman, boards the last night train, not knowing that it is a passage between this world and the realm of the undead. As she travels, strange things start happening and the power shuts down. She can't tell if all the puzzles she's encountering are real or if she's trapped in a dream. And to make matters worse, a ghost girl appears out of nowhere. Where did she come from?
