The Great Forges is a hazy valley scarred and scorched by volcanic activity. One furnace remains ever-active, spilling molten rock down the slopes, channeled through canals and aqueducts, directed to dozens of forge sites. At various junctures along the way, air elementals contribute their efforts in sustaining the heated flow. During the Creation War (1486 DE - 8777 DE), this region grew into an expansive forge-works, providing Covenant armaments for the ongoing conflicts across the universe.
The Demon Spawn War, spanning from 89 GE to 269 GE, witnessed a surge in production and the accumulation of wealth by those catering to the needs of the millions of soldiers dispersed across the Quara'tun System. During this conflict with the demons, this region and the surrounding world operated under the command of Asmodeus.
