Arkhona is a Fortress World of the Kharon System, located in the galactic northern marches of the Segmentum Obscurus, in the dead centre of a void of star systems right on the edge of Imperial-settled space. Kharon is a trinary star system, consisting of three suns locked in orbit with one another. The fifth planet of the system, Arkhona is a former Imperial Fortess World first settled tens of thousands of standard years ago before the birth of the Imperium of Man.
Although the settlements of Mankind at one time stretched across all of its continents, when representatives from the Inquisition's Ordo Xenos arrived recently they found that the entire human population of Arkhona had been destroyed, later determined to be the result of an unexpected incursion by the Tyranids. Shortly afterwards, the Inquisitors themselves were lost under terrible circumstances, thus setting the terrible events of the conflict on Arkhona into motion.
Arkhona is the first world that will serve as the setting for the massively-multiplayer online third-person shooter game Warhammer 40,000: Eternal Crusade, where players playing as the Eldar, Space Marines, Orks or Chaos Space Marines can battle each other in massive online battles.
