The narrative plunges Klein into the stark reality of his new existence as a penniless history graduate in the Loen Kingdom, a world mirroring Victorian England with its nascent industrialization and rigid class structures. Haunted by the original Klein's mysterious suicide and his own crippling poverty, Zhou Mingrui, now Klein, attempts a "luck enhancement ritual" from his past life, a seemingly innocuous act meant to secure a job. Instead, this ritual spectacularly backfires, tearing open a gateway to an ethereal gray fog. He finds himself seated at the head of a colossal stone table in a majestic, fog-shrouded palace, accidentally summoning two strangers: Audrey Hall, a curious and wealthy noblewoman, and Alger Wilson, a stern and experienced Beyonder from the Church of Storms. Overwhelmed but quick-witted, Klein seizes the opportunity to establish himself as the enigmatic "Mr. Fool," the mysterious host of this impromptu gathering. He leverages their awe and confusion, subtly probing for information about this world's hidden mystical underbelly. During this inaugural meeting, Audrey and Alger reveal the existence of "Beyonders," individuals who gain supernatural powers by consuming special potions, and the inherent dangers of "losing control." They discuss potion formulas, the "Blasphemy Slate," and the various Beyonder organizations, providing Klein with invaluable insights. Klein, in turn, subtly guides Audrey to seek a "Spectator" potion formula from Alger, offering himself as a powerful, neutral witness. The meeting concludes with the establishment of the "Tarot Club" and the agreement for weekly gatherings, leaving Klein with a thrilling, terrifying new avenue for power and information, albeit one built on an elaborate deception he must maintain.

Following the Tarot Club's first meeting, Klein's life takes a decisive turn when he's confronted by Dunn Smith, a Nighthawk Captain from the Church of Evernight, who subjects him to a dream interrogation. Dunn, a Beyonder himself, reveals that Klein's survival from his suicide attempt is peculiar and links him to the disappearance of an ancient, powerful notebook from the Antigonus family, a relic whose true significance Klein is yet to grasp. Faced with the stark choice of either joining the Nighthawks as civilian staff or being treated as a prime suspect, Klein reluctantly agrees to cooperate. Dunn then reveals the terrifying truth behind Beyonder powers: the constant risk of "losing control," leading to madness, mutation, or death. This grim reality, coupled with the revelation that a previous transmigrator, Emperor Roselle, had left behind a diary hinting at the concept of "digestion" and "acting" for Beyonders, weighs heavily on Klein. Despite the dangers, Klein realizes that only by becoming a Beyonder can he hope to protect himself and unravel the mysteries of his transmigration. Given a choice of incomplete Beyonder pathways, he thoughtfully selects "Seer," a path focused on divination and mysticism, even though it lacks direct combat abilities. His decision sets him on a perilous course, intertwining his fate with the Nighthawks and the deeply buried secrets of the Antigonus notebook, a path fraught with both promise and unseen perils.

Klein officially begins his journey as a Seer, undergoing the potion concoction in the Nighthawks' alchemy room under Old Neil's guidance. He experiences the immediate, disorienting effects of the potion, gaining "Spirit Vision" but also suffering from glabella spasms and heightened sensory input. Old Neil, a seasoned Mystery Pryer, teaches him the basics of mysticism, including pendulum dowsing and the interpretation of symbols, while also emphasizing the importance of daily "Cogitation" to integrate his new powers. The most pivotal revelation comes when Klein discovers pages of Emperor Roselle's secret diary, written in his native Simplified Chinese. This electrifying find confirms Roselle as a fellow transmigrator and, more importantly, explicitly outlines the "digestion" and "acting" method as the true key to mastering Beyonder powers and avoiding losing control. Armed with this groundbreaking knowledge, Klein decides to actively "act" as a Seer by joining the local Divination Club, using his meager funds to pay for entry and offering his services. His first act involves a "free" divination for a novice named Glacis, where he subtly uses his Spirit Vision to diagnose Glacis's health, a small step in his new identity, but a significant leap in understanding his path.

Just as Klein begins to understand his new role, the lurking dangers of the world manifest violently. He is ambushed in his new apartment by a member of the Secret Order, an ancient organization tied to the Solomon Empire and the Antigonus family notebook. Forewarned by Dunn Smith in a dream, Klein manages a tense standoff, using his revolver's empty chamber as a bluff, before Nighthawk Beyonders intervene. The intruder, a "Clown" Beyonder, is apprehended after a brief, chaotic struggle that highlights the Nighthawks' unique powers. The incident confirms the Antigonus notebook's immense importance, as the Secret Order was desperate to retrieve it. Nighthawk discussions reveal that "Clown" is the Sequence 8 advancement from "Seer," a surprising connection that further validates Roselle's "acting" insights and the concept of Beyonder pathways. Klein participates in the aftermath, searching for extraordinary materials from the deceased Clown, Ray Bieber, solidifying his understanding of Beyonder ecology. This confrontation, though terrifying, serves as a brutal baptism for Klein, forcing him to accept the constant threat he faces and reinforcing his reliance on the Nighthawks and the enigmatic Tarot Club. He now knows that his journey as a Seer is inextricably linked to ancient conspiracies and the ever-present danger of losing control, pushing him to further embrace the "acting" method as his best defense.
