Sometime after Lucius Dragen became the new lord of Helgen, he began honoring his new alliance with House Harrigon, a smithing house from the Stormlands. Lord Jorthos Harrigon married his true-born daughter Larinna to Lucius.
A few weeks after the marriage, Lucius began violently tormenting Larinna, but was subdued by his wife almost every time, and lost his left eye during one of his drunken outbursts. When Larinna's father heard about these attacks, he began marching North towards Helgen with his army, intending to kill Lucius. Having married Lord Jorthos' bastard daughter Arrena, Ser Ethan Snow was able to smuggle Larinna out of Helgen and send her south with a small cavalry, and they met the Harrigon forces in the Riverlands. Larinna was able to convince her father to head back to Gornworth without her, telling him that she could control Lucius.
