A nigh-universal mechanical component--the essential artificial--was of great use to the tinkers and smiths of Gnomeregan. But during the frantic exodus from our city, no one remembered to take any of these devices with them! And I need a large supply of them for work I will soon undertake.
Please, go into Gnomeregan and get me some essential artificials. You'll find them in the deeper areas of our city, held in containers called artificial extrapolators.
