Erium isn't a continent, but is a series of cities located in a gigantic underground cave system that is beneath the South Pole of the planet. All races mix together here, and they research everything that the other countries don't, and they also research human's, the mind, and things to improve or change humans. Once the infection reached them, half of the cities are safe, while the rest are in chaos. The tunnels connecting the cities are deathtraps, with infected hiding everywhere and bodies filling the tunnels because of ambushes by both infected and bandits. Out of all of the places hit, this place is in the most turmoil with no actual division between safe zones and infected zones.
