A legend spoke of an alien man who appeared suddenly and inexplicably in Salador, which event was remembered around the Riftwar. Nothing is known about that man who spoke no known language, although the priests tried to determine his origins; this memory was the first inkling about the rifts. 
Duke Borric and his retinue stopped by Salador on their way to Rillanon, to warn the Kingdom of the impending war, and were hosted by Duke Kerus.
Later in the conflict, Duke Kerus was executed by King Rodric, on suspicion of treason, and was replaced by Lord Richard of Dolth. He was killed shortly and the dukedom was left lordless for a while. 
King Lyam awarded the dukedom to Princess Carline and Laurie of Tyr-Sog before they were married. The line became the "Du-Salador" line.
