Overview
Lord of Mysteries' main story follows the player's original Beyonder character through the early arcs of the source material from a fresh perspective. The player is not Klein Moretti; the player walks the streets of Tingen alongside Klein, occasionally crossing paths with him as an NPC, and unlocks 'Mr. Fool's history' visions that show Klein's canonical events from inside the Beyonder world.
Main quest structure
The campaign is divided into Acts. Act 1 (the Crimson Test build) covers the player's induction as a Sequence 9 Beyonder in Tingen, the first dungeon investigation, the introduction of the Seven Orthodox Churches and the Nighthawks, and the player's first promotion ritual to Sequence 8.
Subsequent Acts move the player to Backlund, introduce the Mandated Punishers and the Machinery Hivemind, and surface the long-tail faction warfare and raid arcs.
Each Act ends with a story-locked encounter that adapts a setpiece from the novel. The encounters are reframed for the player's perspective: events Klein causes in the novel are events the player witnesses, helps with, or attempts to investigate from the outside.
Mr. Fool visions
Throughout the main campaign, the player periodically receives a 'Mr. Fool' vision: a cinematic flashback to a scene from Klein's canonical journey, narrated by Klein in his Mr. Fool persona. The vision triggers when the player crosses geography or encounters NPCs that overlap Klein's history. Mr. Fool visions are non-skippable on first encounter and become rewatchable from the player's home journal afterward.
Visions serve a meta purpose. They reward novel-reading players with on-screen recognition of canonical scenes; they educate non-novel-reading players about the world's mythology in small digestible chunks; and they provide narrative cover for why a brand-new Beyonder's journey winds through the same landmarks Klein walked.
Side quests
Side quests cluster into Pathway-themed lines. A Seer character finds divination booths to staff, runaway puzzle-novel manuscripts to read, and tarot-decks to bless. An Apprentice character finds locked doors to pick, rumours to chase, and old workshops to inventory. A Spectator character finds public spaces to monitor, tutoring jobs to take, and dream patients to soothe.
Completion of side quests scores Acting Method meters in addition to standard XP and currency. Side-quest density is highest in Tingen; later cities surface fewer but longer side quests.
Investigation and detective work
Many quests are investigations rather than fights. The player examines crime scenes, cross-references Beyonder lore in the player's home journal, conducts divinations, and decides which suspect to confront. Outcomes branch: a Seer player who divines correctly may identify a culprit and arrest them through a Beyonder-only mechanism; an Apprentice player may find a hidden passage and ambush them; a Spectator player may infiltrate the suspect's mind and extract a confession.
Investigations have multiple solutions. The same case can be solved differently by different Pathways, and the rewards are flavoured to match: a Seer earns a divination prop, an Apprentice earns a key cosmetic, a Spectator earns a hypnosis trinket.
Cinematics
Story scenes are presented through real-time cinematics rather than pre-rendered FMVs. Lighting, weather, and player-character clothing carry over from gameplay into cinematics. Voice-acted lines play in the player's selected voice language; subtitles cover the rest.
Choices and reputation
Major story choices feed faction reputation, Acting Method meters, and dialogue branches downstream. Choices are not 'good vs. evil'; they are 'how does your character process this situation?' decisions framed by the Pathway Archetype.
Branching can affect which NPCs survive a given Act, which faction extends a hand to the player at a key meeting, and which Sequence-advancement potions the player can craft cheaply later. Branches converge on Act endings to keep narrative coherence; the path to the ending is what changes.
