Best ForGroups who want sci-fi exploration with a Middle Eastern-inspired setting, ship-based campaigns, and a mix of trade, intrigue, and cosmic mystery.Sci-fi fans who want Pathfinder 2e's tactical depth with plasma rifles and starships. Great for PF2e veterans looking for cross-compatible space adventure.
HighlightsSetting blends sci-fi with Middle Eastern mythology and Icon worship, Darkness Points create a GM resource that escalates over the session, detailed ship customization with five crew roles in space combat, ten factions provide a political backdrop for intrigue campaignsFree rules on Archives of Nethys, deep tactical combat, cross-compatible with PF2e, distinct class identity
ConsiderationsSpace combat uses a separate five-phase subsystem with added complexity, praying to the Icons is the only reroll mechanic and it always costs a Darkness Point, mystical powers chapter is brief compared to the setting and combat chapters, setting is tightly coupled — 36 star systems with specific loreSteep learning curve, fewer classes and options than PF2e (still growing), tactical starship combat rules deferred to a future supplement with current rules being narrative only
