The historical event known as the Second Birth occurred in the history of the Yevetha following the departure of the Galactic Empire from N'zoth around 5 ABY.
Before the Empire came to their region, the Yevetha had established settlements on eleven colony worlds, a process that relied upon sublight travel. However, when the Empire pulled out, the Yevetha found themselves in possession of hyperdrive and hypercomm technologies. With these advancements, they initiated the Second Birth, characterized by the swift colonization of twelve more planets.
