A nearly atmosphere-less, tidally locked planet orbiting a red dwarf star, Gei Hinnom was the first place human explorers discovered a dedicated Prothean burial ground. While a few sites were saved for posterity, Eldfell-Ashland Mining successfully lobbied to scout the rest of the planet for element zero and soon was embroiled in a scandal. Mining teams were looting gravesites searching for eezo and other treasures, and many got rich off the so-called "cemetery business". While EAM officially brought a stop to the looting, its mining teams remain on the planet prospecting the unclaimed territory and taking their ore to the Pamyat system for refining.
TRAVEL ADVISORY: Armed conflicts have broken out between miners and scientists staking claims to Prothean ruins. Visitors are advised to employ security while exploring unknown regions of the planet.

- Appropriately for Hades Nexus, the name "Gei Hinnom" literally means "The valley of Hinnom" in Hebrew but is translated as "Hell" in the New Testament of the Bible. The system's name "Sheol" means "abyss" and is from the Old Testament.
