Game of Thrones White Wolf

After Jon is transported into this world, he asks himself a question: can the Night’s Watch save the Seven Kingdoms?

Answer: the Night’s Watch can’t save the Seven Kingdoms.

So Jon leaves the Watch. After he becomes a lord in his own right, he asks himself again: can a single lord save the Seven Kingdoms?

Answer: one lord still can’t save the Seven Kingdoms.

So he sets his sights on the Iron Throne—the throne that should’ve been his—and launches a challenge for it.

P.S. The protagonist is Jon Snow. The story kicks off when he heads south to take part in the War of the Five Kings.
