Baelor Targaryen is King and his journey to the Iron Throne was not an easy one. He is the younger twin to his brother Jaeryn Targaryen. Their mother was a Lannister by blood, Cersei Lannister. Jaeryn had desires to invade the east and was deposed as King for his ambitions. His Dragon killed and he locked away in the tower on Dragonstone.
An Other named Red freed Jaeryn and promised him revenge and great power if he would wear the crown of the Night King. Red recovered the crown from ocean floor of the Narrow Sea and using blood magic opened it. Since burying the dead was outlawed in Westeros they traveled to Essos to raise the dead and bring the long night again.
When Baelor received word he traveled by Dragon with his sister Kaeryn and his other brother Daemon. The long night lasted three years in Essos and it was Princess Kaeryn who killed the Night King this time, as Aegon foresaw. This time they locked the crown and the horn in a room guarded by Watchers. A new guard created for the purpose of keeping the crown safe.
Kaeryn and Daemon spent the rest of their lives hunting the Others to kill them. After seven years they found the Others and destroyed them. Once again peace returned to the world and the great Kingdoms of the East and the West. The Night King never rose again to make war on the realms of men.
