Edmure Frey

Edmure of the House Frey is the firstborn son of former King of the Trident Ryman Frey. Following his father's death and the Sack of Riverrun, Edmure would flee to the Bay of Claws, and then across the Narrow Sea.

The Lion's Dawn
Edmure, wounded in the fighting, rests at Riverrun. When Byron begins his coup and allows the Lannister army into the city, Byron's sellswords break into Edmure's room. While Maester Jason Wycombe delays the soldiers, Edmure escapes out an open window. Using a secret passage, Edmure boards a boat and rows to safety away from Riverrun.

Edmure would make it to the Bay of Claws, where he attempts to stay hidden, but rumours about his true identity spread around the region. Byron's assassin Ironside Hughs arrives in the Bay of Claws disguised as a hedge knight, and attempts to kill Edmure in the middle of the night. Edmure kills Ironside by smashing a candle into his face then stabbing him.

Edmure, fearing more assassins, flees across the Narrow Sea.
