I just came up with an AU where Fitz was in a Nettle like situation where his mom raised him and he didn’t know who his dad was. This is ground breaking, I know. Anyway, really think about how cool it could have been like I have so many ideas.
Fitz could Wit-Bond to a wolf in the mountains when he’s kinda young. The Fool could live in a tent or a small cabin in the woods then visit Fitz every once in a while, they could actually have a childhood together. After a trip in the woods Fitz, Keppet, could return to his mother dead, courtesy of Queen Desire trying to find him but his mother lying to the people she sent. Keppet taking a lock of her hair and braiding it into his own then he has to run because the guards are returning.
The overall story could be him first running to Jhaampe and trying to explain to his Sacrifices how his family was attacked by Six Duchies soldiers. Kettricken and/or Rurisk then trying to discuss it with the Six Duchies but that only gets Regal sent their way. After Regal inevitably tries to kill him Keppet decides to travel all the way to Buckkeep himself. Along the way he may discover travel companion such as Beloved, his wolf, and Burrich.
