For the sake of this story, I'm going to make one geographical change.
Skagos (including the island of Skane), which will be the MC's domain, will be moved to the middle of Westeros, a little higher to the right of the paps and lower to the right of Widow's Watch, without being far from Westeros.
Also, this story is for my amusement, so expect a cheated system and anything, I'll try to keep this story meaningful, but don't expect a serious story.
