Now members of the Starfinder Society and captains of their very own ship, the heroes head to the planet Castrovel, home of some of the best universities in the Pact Worlds, to research the clues they found on the mysterious asteroid. On Castrovel, their findings point them toward an ancient elven temple-city called the Temple of the Twelve, lost deep in Castrovel`s teeming jungles. But, the heroes must contend with two other factions - the exiled Corpse Fleet of Eox and the Cult of the Devourer - who are also interested in the asteroid`s secrets and have their own agendas for the ancient alien superweapon - if they can find it first! A Starfinder Roleplaying Game adventure for 3rd-level characters, Temple of the Twelve is the second part in the Dead Suns Starfinder Adventure Path.
