Long time ago, Gehenna meant something to a lot of folks in fancy suits. The Company used it as a testing ground for tech too dangerous for more civilized corners of the galaxies, chewed it up and spat it out. Now the Company's gone, and all that's left is a rock. Whatever they were testing for, it seems they didn't like the answer.
— In-game description

Gehenna is a rocky planet that once was utilized by Jakobs as a testing ground for powerful technology deemed too dangerous to be tested elsewhere. Some buildings on the plant such as in Vestige are reminiscent of Japanese temples, while lifestyle for its inhabitants are close to American Old Western culture such as pistol dueling, train robbing, and saloon fights.


The Jakobs Corporation developed an interest in Gehenna after the discovery of Core, a rare element found exclusively on the planet and which had supposedly multiple purposes. A rapid colonization of the planet started afterwards and Jakobs began multiple projects to find a use for Core. All of this was done under the name of "the Company", perhaps to hide their true intentions, as well as mining operations in areas like the Obsidian Forest to excavate Core.

Under the "Company" name, numerous projects were being developed, including bioengineering and bioweaponary, all of which centered around the exploitation of Core. One of the major projects was called Project Ruiner, a massive bio-weapon created by mutating the local devil population with Core.

Eventually, the Ruiner became impossible to control, prompting the Company to abandon the planet en masse. Jakobs proceed to bomb all facilities to destroy all evidence of their projects, however large caches of what would eventually be called Company Tech, survived the bombings. The Company soon left Gehanna, abandoning workers and civilians who chose to stay behind

In the present, most people still living on Gehanna have descended from the original workers left behind after the Company abandoned the planet. The Devil Riders, a bandit group that utilizes tamed Devils in their numbers have risen to become a major threat to the local population.



  • Gehenna (גיא בן הינום) or Gehinnom (literally translated as "Valley of Hinnom") is a small valley near Jerusalem. In the Hebrew Bible, Gehenna was initially where some of the kings of Judah sacrificed their children by fire. Thereafter, it was deemed to be cursed location.
    • In Christianity and Islam, however, the word "Gehenna" is an analogue to Hell (known by the latter as Jahannam).
    • In rabbinic literature, Gehenna is also a destination of the wicked. In later times it's similar to purgatory where one is judged based on one's life's deeds, or rather, where one becomes fully aware of one's own shortcomings and negative actions during one's life.
