Golarion: The World of Pathfinder and Its Core Regions

Golarion is the primary campaign setting for the Pathfinder Roleplaying Game, published by Paizo Inc. and detailed across the Lost Omens line of sourcebooks. The setting provides the geographic, cultural, political, and cosmological framework within which published adventure paths, organized play scenarios, and home campaigns are situated. Understanding Golarion's structure — its regional divisions, dominant factions, and cosmological architecture — is essential for Game Masters building encounters, players grounding characters in lore, and researchers navigating how the Pathfinder RPG works as a conceptual system.

Definition and scope

Golarion is a fictional planet orbiting a star called the Sun within the solar system known as the Golarian system, situated in the Material Plane of the Great Beyond cosmology. Paizo first introduced Golarion formally in 2007 as the setting for the Pathfinder Chronicles campaign setting, and the world has since been detailed across more than 40 Lost Omens sourcebooks covering individual nations, cultures, deities, and historical epochs.

The setting's geographic and political center is the Inner Sea region, a large inland sea bordered by two continents — Avistan to the north and Garund to the south. The Inner Sea region functions as the primary operational theater for the majority of Paizo's published content, including all six volumes of the core Adventure Paths and the full catalog of Pathfinder Society organized play scenarios. The broader world of Golarion also includes Tian Xia (an East Asian-inspired continent to the east), Arcadia (a western continent), Casmaron, and the polar continents of Iobara and Sarusan, though these regions receive comparatively limited published development relative to the Inner Sea.

The Pathfinder Inner Sea Region Reference catalogues the 40-plus nations of Avistan and Garund that comprise the primary play space. Paizo designates the Inner Sea region as canon-default for all organized play and most Adventure Path publications.

For the cosmological layer, Golarion sits within a 9-plane cosmological structure that includes the Material Plane, the Positive and Negative Energy Planes, the four Elemental Planes, and the Outer Planes — the latter hosting the domains of deities catalogued in the Pathfinder Deity and Religion System.

How it works

Golarion operates as a structured reference framework across two interdependent layers: geographic-political and cosmological-metaphysical.

Geographic-political structure divides Golarion into named nation-states, each with defined alignment tendencies, dominant cultures, languages, government types, and relationships to major factions. The Inner Sea region alone contains more than 40 distinct political entities. Key examples include:

1. Absalom — The City at the Center of the World, the largest city on Golarion and the headquarters of the Pathfinder Society, located on the Isle of Kortos in the Inner Sea.
2. Cheliax — A devil-allied empire in southwestern Avistan, governed by House Thrune through an infernal compact, and a frequent antagonist presence in published adventures.
3. Ustalav — A Gothic horror-themed nation in northeastern Avistan, featuring strong ties to undead, necromancy, and the Whispering Tyrant's legacy.
4. Osirion — An ancient Egyptian-inspired nation in northern Garund, notable for pyramid tombs, powerful pharaohs, and extensive undead threats.
5. Varisia — A frontier region in northwestern Avistan and the setting for foundational Adventure Paths including Rise of the Runelords.
6. Mwangi Expanse — A large central-western Garund region featuring extensive jungle terrain, multiple indigenous cultures, and significant Lost Omens sourcebook coverage as of 2021.

Cosmological-metaphysical structure governs how magic, death, afterlife, and divine power function within the setting. Deities in Golarion are distributed across the Outer Planes and grant divine magic to clerics, champions, and oracles through the divine spellcasting tradition. The Pathfinder Magic Traditions reference covers how arcane, divine, occult, and primal traditions map onto Golarion's cosmological sources.

Common scenarios

Golarion's regional structure determines encounter type, faction affiliation, and thematic scope in published content. The contrast between Inner Sea nations illustrates how regional selection shapes gameplay:

• Cheliax vs. Andoran: Cheliax represents an authoritarian, devil-aligned empire; Andoran is a democracy-modeled nation emphasizing individual freedom. Published content frequently frames these two nations as ideological adversaries, with the Eagle Knights of Andoran opposing Chelish slavers in adventure narratives.
• Urban play (Absalom) vs. wilderness play (Varisia): Absalom scenarios concentrate on faction politics, guild intrigue, and dense urban encounter maps. Varisia scenarios involve ruin exploration, ancient Thassilonian magic, and wilderness hex-crawl structures.

Pathfinder Adventure Paths are consistently anchored to specific Golarion regions — Age of Ashes in Isger and Huntergate, Extinction Curse in the Circus of Wayward Wonders and Kortos, and Abomination Vaults in Otari. Regional grounding determines available languages, encountered creature types, and ambient political conflict.

The Pathfinder Golarion Setting Overview provides macro-level reference across all regions, while the Lost Omens Sourcebooks series delivers nation-by-nation depth — with volumes dedicated to individual regions such as the Mwangi Expanse, the Grand Bazaar of Absalom, and the Knights of Lastwall.

Decision boundaries

The primary distinction within Golarion content is between canon Inner Sea material and underdeveloped peripheral regions. Paizo's published content concentrates roughly 85 percent of adventure and sourcebook material within the Inner Sea region. Game Masters operating outside that zone — in Tian Xia, Arcadia, or Sarusan — work with thinner published support and must construct more setting detail independently.

A second boundary separates Pathfinder First Edition lore from Second Edition (Remaster) lore. The Remaster publications released beginning in 2023 updated Golarion canon in areas touching on deity mechanics, the removal of alignment as a cosmological absolute, and revised divine tradition structures. Pre-Remaster sourcebooks remain available but may conflict with current rules references. The Pathfinder 1E vs 2E Comparison addresses these divergences at the mechanical level.

A third boundary applies within organized play: Pathfinder Society scenarios restrict available Golarion regions to those officially sanctioned by the current season's campaign, limiting where characters can operate within the setting's geography. Home campaigns carry no such geographic restriction.

The full Pathfinder RPG reference index covers published rules systems, setting materials, and organized play infrastructure in structured format across all major Pathfinder publications.
