From the fringes, the unknown beckons. Pathfinder Dark Archive contains secrets that any player or GM can use to reveal the paranormal lurking in their Pathfinder games! This spine-tinglingly secretive 224-page softcover rulebook presents two new character classes perfect for delving into the unexplained: Unleash the untold power of your mind as the psychic or leverage supernatural secrets and mystic implements as the thaumaturge! Beyond these new classes, eight secret case files each provide player options, GM tools, and lore into a different paranormal topic, including: • Strange cryptids glimpsed in the night, gear to track them, and the powers you might gain by surviving an encounter with one • Cults and esoteric belief, with apocryphal divine magic and the secret of becoming a living vessel for an eldritch being • Temporal anomalies, with archetypes that skim along the surface of time and a new mystery for oracles unbound from causality Each file concludes with a short adventure to immerse players in the paranormal, spanning across Golarion?play all eight to uncover the inexplicable phenomena of the Age of Lost Omens! The pocket edition presents the same contents as the standard edition in a smaller sized softcover for a lower price and better portability.
