Dayna and Tarrant’s first assignment as Liberator crew members is to visit the planet Obsidian and investigate two things: rumors that Blake had fled to that planet after evacuating the Liberator, and the possibility of using Obsidian as a base from which to fight the Federation. But Servalan and her troops arrive to take over the world, and the people of Obsidian reveal the weapon which has kept them safe from the Federation all this time.
