He is living in new castle because he was born here.
He didn’t really do much with his life, he never thought about moving out.
The dream that was born on the day he pulled the sword out of the stone has been the driving force in his life.
While others found good jobs and got a wife and kids , Arthur kept studying the blade.
Who knows if he has a good idea and finds the one in his, might get him to reconsider living in new castle.
Getting out of his bubble is gonna take some time but who knows, these contracts might be just the right thing to help him achieve that.
