The Forge was once an abbey built and cared for by a small sect of dwarves who worshipped Torag. Some years ago the dwarves who lived there were corrupted and started to venerate a long ago banished demon instead. Those who converted to this forbidden cult slew the rest and desecrated the abbey.
They were all killed by a party of adventurers led by Gromm Silverax, a Dwarf who was related to one of those Dwarves slain by the cultists.
After the cult was extinguished, the abbey lay bare and its secrets were forgotten about until Arjirra, after hearing of the cult, decided to use the abbey as a studious retreat.
