The base was presumably established by Hreidmar after his previous base was discovered for a second time by an adventurer during Forgettable Tale of a Drunken Dwarf. Although the adventurer's memory was wiped by his Ogre shaman, Grunsh, he presumably decided it too big of a risk to remain there. Some time later, Commander Veldaban and his "lady friend" Hilda discover the base while investigating kidnappings in Keldagrim East, and they are discovered, causing Hilda to be turned into a Chaos Dwarf and Veldaban's memory to be wiped after being briefly trapped in the base's office.
