Starfinder Adventure Path #36 (GDR)

A favor for their best friend and ally brings the player characters to the ocean planet of Entha, which the Company is terraforming into a paradise for rich dilettantes. The churning water world is home to many mysteries, including a fantastic underwater realm of powerful magic. Now the crew must save an underwater rig from destruction, rescue the workers there, and somehow win the friendship of a strange alien species. But the Company manager on Entha is a dragon, she’s got a team of aquatic alien troubleshooters, and the PCs are the trouble that needs to be shot.
