Tag was a soldier in Buckkeep like his father Reaver. After Regal crowned himself King, young Tag believed in the lies that his true King was dead because Kettricken and Fitz had conspired against him, and so took Regal's colours. He was serving Regal's coterie, protecting them in the road to the Stone quarry. When he met Verity in the Stone Garden, he understood that Regal indeed was a pretender and left his service. Verity charged him to return to Buckkeep and tell people he would return to put his queen on the throne and that there would be a true Farseer heir. He also commanded that Tag would from now on be at Patience's service.
Tag later had a son, Tagsson, who became a minstrel.
