"You're not supposed to be here," the boy speaks in a monotonous voice. "You've fallen into the wrong world." (Or Glorfindel wakes up in Westeros instead of Middle Earth after he was reborn/GOT Season 8 Fix-It)

With the reign of the Mad King yet to come, the lands of Westeros find themselves visited by a group of strange yet knowledgeable vagabonds that call themselves "the Istari". What do they want, and more importantly, what will they do to get it? Will they succeed at their mysterious goals, or will the Game of Thrones destroy them as it has destroyed so many others?
