Esoteric Detective Strange Stories

[Steam Age + British Secret Cult + Amnesia Detective + Cthulhu-style Investigation + Second Time Travel] "If a diary records your past, but you can't read the words in it, would you believe it?" Adrian woke up lying on the shores of Fog Harbor. No identity, no memory, not even a name. The only thing accompanying him was a snakeskin diary soaked in seawater. There are four unanswerable decisions left in the diary: Where did humans come from? Why do words exist? Who is the oldest god? Why does the chief flower bloom? In order to pursue the truth, he joined the Royal Bureau of Investigation and became a detective investigating supernatural events. But as the investigation deepened, he gradually discovered: This is not his first time traveling across the world. Before losing his memory, he was a recorder of another era. Some people call him: the twelfth librarian. He once wrote history. Now, he must rediscover his history. At the end of the fog, there is a question waiting for his answer: "Adrian, do you really want to know who you are?"
