Game of thrones: jorah mormont
Premise: A modern man awakens in the body of Jorah Mormont, the disgraced exiled lord of Bear Island, on the very day King Robert Baratheon's procession arrives at Winterfell (Episode 1 timeline). Armed with the Northern Dominion System, he must rebuild Bear Island from a poor, remote holding into a power that can survive the coming Long Night — and the game of thrones itself.
