With data recovered during the previous adventure, the characters have proof of an extant deep-culture site and the coordinates to travel there. What they lack is the technology to dive into the sun for a visit. A member of the Corona Artifact Divers, daredevils who delve into the sun's atmosphere for thrills and profit, has just what the heroes need. However, this genius diver is in debt to "business people" who have reclaimed the sun-diving starship to recoup their investments. The characters must go to the Burning Archipelago bubble of Verdeon, deal with those holding this "sundiver" starship, and take the vessel into the sun. Upon doing so, the heroes find a strange bubble-city called Noma, a discovery their employers at the Deep Cultures Institute have long sought, and uncover clues to a greater mystery!
"Sun Divers" is a Starfinder Roleplaying Game adventure for four 5th-level characters. This adventure continues the Dawn of Flame Adventure Path, a six-part, monthly campaign in which the players uncover a plot that threatens the Pact Worlds sun. It also includes an article on organized crime in the Pact Worlds, a gazetteer of the mysterious bubble-city of Noma, and a selection of new monsters from within the sun and the planes.
