Like its predecessor, the game takes place in a realistic and modern setting. The campaign follows multi-national special operations unit Task Force 141 and Mexican Special Forces unit Los Vaqueros as they attempt to track down terrorist leader, who is in possession of American-made ballistic missiles.
In the Game of Thrones pilot episode "Winter Is Coming," Daenerys receives three dragon eggs of green, black, and gold color as a wedding present from the Magister of Pentos, Illyrio Mopatis. He informs her the dragon eggs are from the Shadow Lands beyond Asshai and that time has turned them to stone.
Where Did Daenerys' Dragon Eggs Come From? Even if it isn't Daenerys' dragon egg in House of the Dragon, season 1, episode 2 does come close to it. It reveals that the egg came from a dragon called Dreamfyre, which is likely the one who produced Daenerys' dragon eggs as well.
