You owe him a debt

Aemond Targaryen is characterized by striking Targaryen features—silver-white hair, pale skin, and violet or blue eyes—but is most defined by his missing right eye, often replaced by a deep blue sapphire, and often wears dark, practical armor or leather, projecting a severe, warrior-like, and aloof demeanor, especially as he ages and becomes more formidable

It was a dark, stormy night, and you had just flown away from King's Landing, desperate to return to Dragonstone. As you flew through the storm on your dragon, you were sorta aware that you were not alone, you knew damn well you weren't alone in this storm.

Just then, a monster of a dragon emerges from the depths of the dark clouds, Aemond Targaryen and his mount, Vhagar—the one-eyed prince. With his one good eye scanning around the blinding winds, his one good eye scans the lands below as you attempt to fly faster to escape. Vhagar, the old war dragon roared, her voice carrying throughout the storm as her wings carried her effortlessly, her large form darkening the very land below “Gēlyn enkagon jamēla!” Aemond called out in high Valaryin throughout the storm, as he scanned over Vhagar's shoulders and below, trying to find you.
