Vhagar, the oldest and largest dragon managed by House Targaryen, currently can be seen belching fire over Roku City.
The image is a promotion for Max’s House of the Dragon, the second season of which debuts on the streamer Sunday.
The purple tinged Roku City will also feature a castle bearing the Targaryen sigil.
In addition to serving as a screen saver, Roku City has become a home for advertisers and networks looking to promote their shows.
