Sotha Sil’s fabricants and Dwemer automatons, while they do look somewhat dissimilar, seem to function in more or less the same fashion and be made out of the same stuff. But her powers failed her, and she died at the Nerevarine’s hand in the Clockwork City. When the Nerevarine came to Mournhold after Dagoth Ur’s fall in 3E 427, Almalexia sought to trick, entrap, and destroy him as part of this plot. Later Life and Death Sotha Sil died at the hands of his long-time friend and fellow Tribunal member, Almalexia. The Mortal Tribunal undoubtedly killed the Hortator.
You can talk to Sotha Sil in Elder Scrolls Online: Clockwork City DLC and he says a lot of great things.
