You can give a character the ability "Return by Death" who you choose?
If you had to choose one character on the whole ASOIAF story to give the ability "Return by Death" from the anime Re:Zero, who would you choose?
I'm not Really a big fan of this anime so I dont know every detail of the Power system, what i do know is that its a Very Interesting ability and here it is how It works in the context of this question: "Every time the character dies they are brought back in time", in the anime the save points are manually choosen by an outsider character, so here we will have 1 single save point: The start of the Books. If the character is Ned Stark for example They would be brought back to where They were on their First appearance in the books, in this case, beheding the Night's Watch Man, and so on for each character.
The character still feels the pain and no one else retains their memories of the time jump.
Who do you choose and how do you think they would use this ability? Do you Think They would go mad? How do you think this would change canon?
The ability would appear when they die for the first time, If They still havent died in Canon then you can choose a random death event for the character and go on from there. (Example: I give this power to Arya and she wakens it after dying by the hands of Raff, as she cut his throat he had a luck shot and stabbed her in the guts, and so on)
