After the incident at Driftmark, King Viserys Targaryen, first of his name, has declared for his sons and grandsons to be sent away from the Red Keep in pairs. He hopes that keeping them away from court will help them bond with each other. Prince Aegon and Prince Jacaerys are sent to Riverrun while Prince Aemond and Prince Lucerys are sent to Runestone in the Vale.
