"Ker-Soth" is the Internet nickname of a fan fiction author who was active between 2004 and 2005. Ker-Soth was one of the earliest authors of the Alternate Trilogy, the series that ultimately led to the Alternative Star Wars Saga. Ker-Soth worked with Brandon Rhea on the Alterate Trilogy and came up with many of its earliest ideas. Due to conflicting ideas, Rhea and Ker-Soth eventually started their own separate series. Ker-Soth wrote a large part of a novel titled Stone Cold, but he became inactive on the internet shortly thereafter.
