The Adventures of Rickon and Osha

I have always wanted to a story on Rickon Stark and Osha. This story occurs after the events of Game of Thrones Season 3's Episode 9. Rickon and Osha have parted company with Bran and the Reeds. Osha turns out to be a reincarnation of Nymphadora Tonks from Harry Potter. Meanwhile, Darth Vader takes an interest in Rickon and sends one of his Inquisitors to fetch Rickon.
