The heavy rain poured down, and the darkness of Salem Port was infinitely magnified. The amnesiac protagonist wakes up in an antique shop filled with rancid smell, with only a notebook beside him that exudes a strange smell. The bloody words on the notes appear and disappear quietly like living things, as if they are telling taboos.
As soon as he escaped from the antique shop, he encountered Old Morris, a member of the "Hand of Ashes" disguised as the shop owner, and then the "Scavengers" followed one after another. In the dark sewers, the "fluorescent rot sacs" emitted a faint light, and the creeping bodies were creepy. In order to seek the truth, the protagonist relies on the power of notes to survive in the sewer maze controlled by the Mole Gang, and battles wits and courage with the Rat King who is parasitized by "brain-eating leeches".
And when he went deep into the waste disposal area, he discovered the inhumane experiment of the Ash Hand - the "Symbiote Prototype". In this desperate situation, can the protagonist uncover the secrets of the notes and his own identity? How will the terrorist conspiracy hidden in the deep sea behind the Port of Salem be rewritten? All the answers lie in this Cthulhu-style thriller.
