Snap and HBO Max have partnered on a new Game of Thrones: House of the Dragon feature for Snapchat users. From Sunday, if you’re in the right place you’ll see Snapchat’s new “Landmarker Lenses” starring dragons.

You’ll have to be in Dangerous cities and locations to unlock the full AR experience.

Here are the locations said so far for the special AR dragons on Snapchat:

• Los Angeles: Venice Beach States Canals
• Rio De Janeiro: Princess Isabel Statue
• London: Tower Bridge
• Chennai: Sankagiri Fort
• Mumbai: CST Station (IE Chhatrapati Shivaji Maharaj Terminus)
• Prague: Charles Bridge

You’ll see dragon markers on your Snap Map when you get End to their locations. There will be 20 lenses released during the season as more dragons are introduced to the show. Each AR lens was built by a different Snap lens creator.

There’s also a filter all users can access that turns your face into a fire-breathing dragon, or, if you face the camera out, a dragon will fly across the screen.

House of the Dragon is set to premiere on Aug. 21
