Unfortunately for Daeron and Aemon, after succeeding in conquering Dorne, it later fell back into Dornish hands in an uprising that would eventually claim Daeron's life. Aemon was named to the Kingsguard when he was only seventeen, where he would serve his cousin Daeron I in his conquest of Dorne. Aemon was said to be very much in love with his sister Naerys, and supposedly cried when he heard that his brother was to wed her.
Aemon grew up to be a skilled swordsman, outshining his elder brother Aegon IV and gaining praise for his martial abilities. Aemon was Viserys II's youngest son and was born circa 138 AL.
