Te Pewa—the Source World—is the fabled planet from which humanity sprung dozens of millennia ago, an age that survives only as fanciful myth. During the long, tortured history that flung humans across the stars and twice nearly wrecked them as a species, the Source World was lost to all knowledge. Moreover, humanity’s descendants have since mutated and engineered themselves for life on other worlds so that, at present, they are a divided, rootless people, longing for identity.
