Treven was a powerful mindspeaker, and well trained in government and executive power. When it became apparent that Randale would never have a son, Treven was selected as Heir and his training as a Herald was accelerated.
Treven married Jisa, daughter of Randale's lifebonded King's Own Shavri and secretly fathered by Herald-Mage Vanyel. Jisa and Treven became lifebonded. When Randale and Shavri died together, Treven became king and Jisa took over her mother's role as King's Own.
