Blood and Steel

He was sent to Essos to secure the new Targaryen reign. He was sent to ensure trade between not only his region but the crown. He was sent to ensure the Blackfyre bloodline was dead. Postponing his wedding, Tywin Lannister sets off for the Free Cities. However, while in Lys, he becomes the target of an assassination that leaves him close to death. All he remembers is a pale haired woman. Kaethryn Blackfyre didn't expect to find a man nearly dead on her way home. Taking him back with her, Kaet nurses him to health, caring for his wounds despite the fact she discovers his mission is to see her family dead. After he leaves to finish his mission, Tywin cannot forget about the girl that nursed him back to health. He can't live without her, so before he returns, Tywin weds her before returning to Westeros, his new Valyrian wife in tow. He doesn't expect to upset Joanna, and he doesn't expect the outcry to come with wedding his exotic wife. He doesn't expect her to become a target for political ambitions and obsessions as she helps him secure their legacy both at Casterly Rock and in the political world. What happens their legacy is endangered by multiple forces? Will they be able to protect the legacy they have worked so hard to create through the use of blood and steel?
