The Blue Opal
The Blue Opal is a dwarven mining company operated primarily in the city of Keldagrim, the capital of the Dwarven Realm. The Blue Opal is a member of the Consortium, a collection of eight mining companies responsible for governing the city and its economy.
During The Giant Dwarf quest, a player can choose to help this company by gathering materials, primarily ore and bars, for its head secretary. After this is done, a player can do some tasks for the director. The director will then let the player join the company as a member, so that they can choose him to have a stone engraving of his head carved onto the giant statue that is in the middle of Keldagrim.
In Forgettable Tale of a Drunken Dwarf, the player can also ask him for help in removing the boards blocking a railway tunnel.
