Astrid Hrethelson

Daughter of Ulred and Alva Hrethelson and Grand Maiden of Nurhst. She is the sister of Hord and and twin of Hrothgar. She is kidnapped along with her sister and mother at the start of the first book, kicking off the Wrath of Hrethel plotline. Her mother's sacrifice allowed for her and her sister Asa to escape from the grasp of the Urbs and flee first to the city of Sessine, and then back to her home island of Hrethel on a smuggler ship.

Wrath of Hrethel
Her and her sister Asa get chapters dedicated to them in the Wrath of Hrethel storyline, where as they're tearing across Tencur to get home, they here about all that their brothers are doing in their name. It grants perspective to what House Hrethel is doing, and how they view their family vs. how the world does. Asa is not surprised that Hord is doing so well in warring in their name. Hord was always a hero in her eyes, and the world's greatest warrior. Astrid was never so convinced. She's immediately worried about Hord when she hears of what he's doing. She can't grasp the idea that the brother she grew up with was now leading sieges and battling commanders all in her name. She feels a twinge of pride along with her worry, but she still isn't as excited as Asa.

This inspires them to rush back home to Nurhst as soon as possible to let it be known that they're alive, and to rule in the abscence of their father and brother, and to tell of their mothers unfortunate fate.
