Ethne was raised in a stone house on the shore of a lake facing the city of Ewyas, the only daughter of Eadwine Ash, a master smith whose work was fine enough for lords and castle gates. Her father was a man of strict, unexplained boundaries: he never once crossed the water to the city, he refused to teach his daughter her letters, and he kept his small household — Ethne and a pair of foundlings taken in as servants — closed tight against the world. Yet he taught her everything else: the trade, the business, the sigils of the nobility, and the use of the blades she demonstrated for buyers. By two-and-twenty she could work the forge nearly as well as he could and handled steel like someone born to it.

When Eadwine and two of his men were killed on an ordinary supply run — a broken cart, an animal attack, an accident by all accounts — Ethne inherited the forge and the household. Something about the scene never sat right with her, but grief and responsibility left no room to pursue it. She crossed the lake for the first time in her life to keep the business alive, and in time carried her trade across the border into the Kingdom of Ardennes, where no one asked the careful questions she had been raised to avoid. While preparing the household's move there, she found her true inheritance hidden beneath the floor of her father's chamber: castle-grade armor and a sword of the finest make she had ever seen — work she had not known him capable of, made for no buyer.

When Inquisitors descended on the Ardennes border country, Ethne took up her father's blade alongside the common levy — and stood out immediately: an unknown woman in castle-forged plate who fought like a lifetime of training, because it was. Brought before Sir Quintus, Lord Commander of the city, she answered every question truthfully, though the truth had a hole in the middle of it she could not fill. Quintus weighed the unanswered questions against her service, set the matter aside, and took her into the King's service. She rose into the King's own guard and, against considerable precedent, was knighted.

The great flood came — divine judgement that swept away the old world — Ethne found King Elryck in the chaos and led him to safety on the mountain. For this she was ennobled. When the waters came a second time and took most of the court with them, Elryck raised her to Duchess, and she took an abandoned keep in the deadlands, naming it Ghostwood. She bore the rank dutifully but never comfortably: a blacksmith's daughter administering a duchy through a scribe, finding relief only when she could trade gown for tunic and return to the forge.

When word reached her that House Sunshield — friends she had believed lost to the flood — had survived and were rebuilding far from the capital, she went before the King and begged release from her oath. Owing her his life, Elryck granted it. Ethne Ghostwood set aside her duchy, crossed two kingdoms, and pledged her sword and loyalty to Lord Lathen Sunshield, entering his service with her small household at her side.
