A Starfinder Second Edition Playtest adventure designed for 1st-level characters.

For millennia, Birnam’s Bubble has been a planet untouched by outsiders, fully encapsulated in an impenetrable shield of unknown energy and protected by powerful automated defenses. Through this barrier, explorers and surveyors have glimpsed pristine settlements, verdant flora, and inexplicable magical emanations—yet no fauna or citizens populate the world’s surface.

As in many other parts of the galaxy, the Drift Crisis changed everything. Now, the energy barrier surrounding Birnam’s Bubble cracks like shattering glass, and shards of this solidified energy have begun to fall through the atmosphere to the planet’s surface, causing significant destruction. Enter the breach and uncover the secrets of the lost civilizations of Birnam’s Bubble before they're lost forever!
