Ever watch an episode of Game of Thrones and felt a bit lost? How far is it to the wall, anyway? And where the hell is this city Daenerys is visiting?
Well, no longer do you have to feel inferior to the book-readers with their map inside the front cover.
A dedicated and very clever person has made a full world map for A Song of Ice and Fire - the books that Game of Thrones is based on - and best of all, they've included character journeys and anti-spoiler modes.
Made by "serMountainGoat" the map covers both major continents in the story, with some other mentioned areas painted in their (probable) locations.
There are also paths that show the movements of each main character - and a control to stop anything that might spoil the story for users. Just tell the map what chapter of the books or episode of the show you're up to, and it will limit the story spoilers to that point.
And the spoiler control is completely up-to-date, too.
The map uses Google Map's familiar controls, and has actually been around since 2012. It went viral in the last 24 hours after its existence was noted by some mainstream news outlets.
As a long-time ASoIaF fan who's been reading the books for well over a decade, I'd never heard of this amazing tool.
I'm not the only one impressed, either, as the book's author, George RR Martin, sent a reply when the map was first completed:
Still, for the purposes of watching the show and getting a better sense of how all the seven kingdoms and the area across the Narrow Sea fits together, this is just perfect.
There's also the excellent A Map of Ice and Fire website, which lacks the story arcs and covers a larger area.
