The Halls of Fabrication is a 12-player trial available in The Elder Scrolls Online: Morrowind. It takes place in Tel Fyr, eventually leading into a rift to Sotha Sil's Clockwork City. The cause of the distress is from somebody accidentally discovering it, and causing its defenses to go "haywire". It has been described as a "snow globe" style "dwemer wonderland" with deadly bosses and environmental hazards.
