With the rising tide of steam power and machinery, who can come close to being a Beyonder? Shrouded in the fog of history and darkness, who or what is the lurking evil that murmurs in our ears?

Waking up to face a string of mysteries, Zhou Mingrui finds himself reincarnated as Klein Moretti in an alternate Victorian-era world. He discovers a realm filled with machinery, cannons, dreadnoughts, airships, difference engines, as well as potions, divination, hexes, tarot cards, and sealed artefacts.

The Light continues to shine, but mystery has never gone far. Follow Klein as he becomes entangled with the Churches of the world—both orthodox and unorthodox—whilst he slowly develops newfound powers thanks to the Beyonder potions. Like the corresponding tarot card, The Fool, which is numbered 0—a number of unlimited potential—this is the legend of “The Fool.”
