Hades Nexus is a cluster located in the core of the Attican Traverse, near the eastern galactic rim, along the northern tip of the Skyllian Verge. In the asari cycle, Hades Nexus was colonized by the First Rachni Collective in 186 BCE, forming up the eastern sector of their domain as they continued to rapidly expand throughout the galaxy. After the Collective's destruction in 53 CE, Hades Nexus fell within Council jurisdiction, but was abandoned due to its distance from Council space, believing it to be indefensible against krogan aggression. In 204 CE, the cluster was claimed and colonized by the Greater Quarian Republic, whose colony of Hekrast would become the capital of the Republic of Hekrast rump state that briefly existed after the First Morning War. Hades Nexus would be lightly colonized by the Systems Alliance in the early 2170s, although the Alliance did not officially claim jurisdiction over the colonies in the region, and therefore did not offend them from the frequent geth heretic attacks that occurred throughout the cluster until 2185 CE. After the Reaper War, the Systems Coalition acknowledged the Republic of Rannoch's claim to the cluster, who recolonized the cluster quite quickly, and have held onto it ever since.
