|Years after Aegon's Conquest|
Year 1 After the Conquest (1 AC) is the year in which Aegon Targaryen was crowned in Oldtown. It would be used as the origin of the Westerosi calendar, used by maesters and educated people use as a reference to date the years. It should be noted that since Aegon coronation didn't take place until he had conquered almost all Westeros between Dorne and the Wall, most of the battles and events of the Conquest itself are paradoxically dated in years 1 and 2 "before the Conquest (BC)".
In 1 AC the Three Sisters tried take advantage of the chaos of the Conquest to declare themselves independent, but the secession was quickly stopped by Visenya with his dragon and an army of Northmen.
- Aegon Targaryen is crowned and anointed at the Starry Sept of Oldtown and becomes King Aegon Targaryen, the First of his Name.
- Marla Sunderland is crowned Queen of the Three Sisters, but is promptly deposed and delivered to Visenya once she reaches Sisterton with Vhagar and a fleet of Northmen under Torrhen Stark.
Titles and Appointments
- Steffon Sunderland is named Lord of the Three Sisters after his sister Marla, after bending the knee to Visenya, renewing his fealty to the Eyrie and delivering his sons as hostages.
