Starfinder Adventure Path Dead Suns

In the Dead Suns Adventure Path, the players take on the roles of members of the Starfinder Society, a loose association of scholars and adventurers who travel the galaxy uncovering the secrets of the past. When a fragment of an ancient alien superweapon surfaces in the depths of hyperspace, its discovery sets off a race to find the extraterrestrial doomsday device. Hopping from planet to planet in both the civilized Pact Worlds and beyond, the heroes must contend with both the undead Corpse Fleet and the nihilistic Cult of the Devourer, each of which seeks to acquire the alien artifact for its own purposes. Can the heroes find and destroy the superweapon before their enemies seize control of it, or will the Pact Worlds' sun go dark and cold, a harbinger of dead suns across the galaxy?
