Tharos the Quick was the Captain of the Guard at Aroughs during the Rider War. He was the son of Lord Halstead, the last to remain in the city with him. He was the brother of Galiana. Tharos met Roran on the roads around Aroughs and briefly talked with him. Later, after the Siege of Aroughs he, like Hamlin in Gil'ead, led a small rebellion against Nasuada's rule which took several months to put down. His motivation behind his rebellion was to avenge the death of his sister while Hamlin's was to avenge his loss of status.
Tharos is described as short and bearded and was seen to wear a plumed helmet when he talked with Roran.
-Tharos's title is only found out after Nasuada reflects on him being a nuisance.
