Lord Lyman protected Prince Aegon and Princess Rhaena Targaryen, extending guest right and refusing King Maegor I Targaryen's demands to turn them over. However, Lyman did not pledge his swords to the fugitive prince and princess, nor did he stir himself from Casterly Rock after Aegon perished at his uncle's hands during the Battle Beneath the Gods Eye. When Prince Jaehaerys put forward his claim to the Iron Throne, Lyman rallied to his support.
