A few but interesting changes have been made to "Game of Thrones" opening credits. It's not easy to keep track of the changes, so here they are. Moreover, a very popular theory about the credits has been confirmed by the company that makes them. You can read more about this theory at the bottom of the article.

First change: it's all about Westeros

For the first time ever, Essos is not included in the "GOT" Opening Titles. Since Daenerys Targaryen has arrived in Westeros, there is no need to feature a stopover in the eastern continent of the Known World.

Our favorite TV series is really coming to an end, as the showrunners told us a few months ago.

Second and third changes

The second change is about the Oldtown and the Citadel. Oldtown appeared in the final spot of the opening credits. The Citadel's appearance confirms that we are going to see more than a few scenes featuring Ser Jorah Mormont and Samwell Tarly in Oldtown, just like this recent theory suggests.

Also, Daenerys Targaryen's location usually gets the final spot in the titles. Instead, we now can see Dragonstone appearing in second position. The Mother of Dragons is now officially one of the Westerosi players.

The Citadel's monk theory confirmed

One of the most popular theories about the "Game of Thrones" credits claims that the calendar/astrolabe featured in the opening sequence resemble the chandelier-like structure we saw in the Citadel's library. Moreover, the magnifying glass used by the Maester encountered by Sam in season 6 is another connection between the opening titles and the Citadel.

We don't know if, as some fans claim, we're viewing "GOT" through the lens of a Maester in the future - maybe even Sam - but we do know that the credits are really connected to the Citadel. An old statement looks now particularly relevant. A while ago, recounting "GOT" title designer Angus Wall’s original pitch for the Game of Thrones credits, producer Greg Spence revealed the story behind the sequence: "Imagine that somewhere in Westeros, there's a mad monk in a tower who actually has created a map of the world.

He keeps track of where everything is happening and what’s going on on that map," said Spence.

We still don't know if this connection with the Citadel will be clarified in the storyline, but there is no doubt, now, that this connection exists. Don't forget: Game of Thrones season 7 episode 2, titled "Stormborn", will air on Sunday, July 23, on HBO.
