From publisher blurb:
In conjunction with d20PFSRD and Rogue Genius Games, the Four Horsemen bring your more character options!
Take to the stars in your next Pathfinder session as one of the sokura—an unusual race from the mind of Tim Hitchcock and the Four Horsemen!
Play a member of a tauric alien race that uses a natural talent for technology to defend its close-knit family against outsiders. Learn of their traditions through song and poetry, before taking up advanced weapons and securing prosperity for your people. Even better, play them as interstellar nomads or scientifically advanced centaurs in a more modern fantasy setting. Decide for yourself how to use this unique race and these new mechanics:
New archetypes: the honored nomad (cavalier) and the mind singer (skald).
New feats: Sixth Sense, Greater Sixth Sense, and Survivor
New racial options: a playable build for the race, variant racial traits, and favored class options.
Four Horsemen Presents: Alien Race: Sokura supplements your Pathfinder collection and gives you new options for bringing space into your fantasy campaign, or a tribal fantasy race into your interstellar game.
