Political map of Game of Thrones 0 ?? 707 (The Dragon and the Wolf): In Season 7 Daenerys Targaryen arrived at Dragonstone with three dragons and an army of Dothraki and Unsullied. Although she took the Lannister stronghold of Casterly Rock, Daenerys suffered defeats when Queen Cersei Lannister, with the support of Euron Greyjoy of the Iron Islands, destroyed her fleet and captured the wealthy city of High Garden in the Reach. In a counterattack, Daenerys devastated the Lannister army and retook the Reach, but later lost one dragon supporting Jon Snow (Jon Snow (character)) in his expedition against the White Walkers. Adding the fallen dragon to his undead army, the Night King broke through the Wall and invaded the Seven Kingdoms.
