Bethany's sister, Barba, was the fifth of Aegon's mistresses, and the girls' father had served as Hand of the King. Both of them had been displaced, however, when Aegon decided he preferred Melissa Blackwood. Lord Bracken trained Bethany with the specific purpose of replacing Melissa.
Bethany caught the eye of Aegon during one of his trips to Stone Hedge, visiting his bastard son with Barba, Aegor Rivers. The king was old, fat, and foul tempered, but found Bethany delighting, and he took her back to King's Landing. She found the embraces of the king distressing, however, and found solace in the arms of a handsome knight of the Kingsguard, Ser Terrence Toyne. When Aegon found out, he forced Bethany to watch as he had Terrence dismembered. Bethany and her father were both executed.
