Cosmo, a mysterious eidolon resembling a corpse in a spacesuit, has been appearing all around the area and wreaking havoc with his space-based powers. He's a powerful entity, and he's difficult to stop and impossible to put down for good. But eidolons don't act on their own; somebody must be repeatedly summoning him and commanding him. To stop Cosmo's depredations, the PCs are going to have to figure out who's currently pulling his strings, and how, and address the problem at its source. Of course, if the person controlling Cosmo realizes the PCs are coming after them, they're likely to call Cosmo to defend them, and the PCs might end up coming face to face with the dangerous eidolon anyway...
