Overview
Klein Moretti (克莱恩·莫雷蒂) is the protagonist of the source material and an NPC in Lord of Mysteries. He is a Seer Pathway Beyonder, founder of the Tarot Club, and the canonical Sequence 0 Fool in the Pathway's god-tier slot. The player is not Klein; the player creates their own Beyonder through Character Creation and encounters Klein through 'Mr. Fool' visions and direct in-game appearances during the campaign.
Background
Klein Moretti is a recent graduate of Khoy University, originally from the Backlund-adjacent middle-class. The opening events of the source material see Klein's body inhabited by Zhou Mingrui (a 21st-century Chinese university student) after a transmigration ritual goes wrong. Zhou inherits Klein's identity, his memories, and a mounting debt; he survives by joining the Tingen Nighthawks under captain Dunn Smith and drinking the Sequence 9 Seer Potion. The two identities overlap and merge over the early arcs.
The game presents Klein as already established when the player arrives in Tingen. The transmigration backstory is referenced in Mr. Fool visions and dialogue but never explained at the introduction; players who have not read the source material learn it gradually.
In-game role
Klein appears in the player's campaign in three modes:
Mr. Fool visions: cinematic flashbacks to Klein's canonical journey, narrated by Klein in his Mr. Fool persona. Triggered when the player crosses geography or NPCs that overlap Klein's history.
Direct NPC encounters: Klein appears in person in Tingen at specific story beats, typically as a Nighthawk colleague or as a senior fortune-teller the player consults.
Sefirah Castle ritual cameos: high-Sequence rituals in the player's Divination Club guild summon Klein in his Mr. Fool persona for short interactions, mirroring the canonical Tarot Club ritual structure.
Codename: Mr. Fool
Klein's codename in the Tarot Club is Mr. Fool. The codename derives from his eventual claim to the Sequence 0 Fool seat; in the early game, the title is treated as honorific and self-given. Within the Tarot Club ritual structure, Klein is the central authority who connects member Beyonders across vast distances and grants them access to Gray Fog commerce.
Pathway and abilities
Klein is a Seer Pathway Beyonder. By the time the player encounters him in the campaign, he has advanced multiple Sequences past the Sequence 9 Seer entry. His on-screen abilities include cinematic-tier divination, control of the Gray Fog, command of the Tarot Club ritual, and at later story beats outright reality-bending miracles. The game keeps Klein at deliberately above-the-player power tier so his appearances feel like genuine encounters with a higher-Sequence NPC.
Klein also accumulates two additional Pathway claims later in the source material: the Door Pathway (related to the Apprentice Pathway) and the Visionary side of the Spectator group. These appear in late-game Mr. Fool visions and final-Act story content; they are not relevant to the Crimson Test beta scope.
Player relationship
The player's relationship with Klein is structured as a colleague-and-witness arrangement. Klein is not a companion who joins the player's party; he is a fellow Beyonder who shares the player's space at specific intersections. Cooperation is mutual but indirect: Klein gives the player advice, contracts the player for ritual support, and at one beat prays for the player to a higher-Sequence entity in the Mr. Fool ritual.
Players who name their character Klein Moretti during Character Creation receive a special introductory cutscene that hand-waves the coincidence. Klein remains his own NPC; the player remains their own original Beyonder.
