Reincarnated as the second son of Rickard Stark, Lelouch retains the memories of his past life and a fierce ambition to lead the North. With cunning and knowledge, he must navigate the treacherous waters of Westerosi politics while upholding the morals, duty, and honor of his new home

Lelouch dreamed about the past glories of his Valyrian family, when they'd held great keeps and their fleets ruled the Narrow Sea. But some nights, he dreamed of a life that wasn't his. He dreamed of an empire, war, and tyranny. Most of all, Lelouch Velaryon dreamed of revolution. (Lelouch from Code Geass inserted into ASOIAF, set in the War of the Ninepenny Kings era).

Perhaps the boy he found could be exchanged for leniency...?
