Cortnay Baratheon

353 AC - Along with his mother and other relatives, Cortnay is taken aboard a ship made for King's Landing in order to avoid the upcoming assault on Dragonstone by the invading Targaryen forces.

354 AC - The Baratheon family that fled during the invasion returns to Dragonstone after repairs to the castle itself have been completed.

359 AC - Following the birth of Cortnay's second true born cousin Emberlei, his grandfather Lord Gerold Baratheon arranges a squireship for him and his bastard cousin Hugo Waters - both under the Knight of the Kingsguard, Ser Oberyn Santagar. This marks the beginning of a lifelong fued between the two.

365 AC - Cortnay and Hugo return to Dragonstone to witness the marriage of their aunt Argella Baratheon to Lord Gerold's vassal Lord Jacaerys Celtigar. It is a grand event, and during the festivities Cortnay is knighted by Ser Ilyn Bar Emmon - the Captain of Dragonstone's Guard, at the behest of Ser Oberyn who's duties to the King required him to stay in King's Landing.
