By now, Daenerys Targaryen's affinity with dragons is one of the best known facts in the Game of Thrones universe – but a fan theory now suggests the creatures aren't actually dragons.
Reddit user 4h0y1m4p1r4t3 pointed out on the platform that, in most fantasy works, dragons are meant to have four legs and wings.
Creatures with two legs and wings – such as Daenerys's "dragons" in the show – are instead known as wyverns.
While the observations were initially related to the video game Skyrim, another Reddit user was prompt to draw a link with Game of Thrones, writing: "Oh s***.
"[Today I learned] Daenerys is not the Mother of Dragons but the Mother of Wyverns."
The mythical creatures controlled by Emilia Clarke's character on the cult HBO show have two legs, meaning they would technically qualify as wyverns, not dragons.
Several fan websites, however, claim that George R R Martin, the author of A Song of Ice and Fire, on which the show is based, deliberately gave his dragons two legs instead of four because he believed that made more biological sense.
Game of Thrones's eighth and final season is currently scheduled to air in April 2019.
Clarke previously described how the production team heightened its attention to detail while filming the last season, to end on a high note.
“Everything feels more intense," she told Entertainment Weekly.
"I had a scene with someone and I turned to him and said, ‘Oh my God, I’m not going to do this ever again,’ and that brings tears to my eyes.”
