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.
