... only thing that is throwing me is that this is supposed to take place 300 before game of thrones? They should be primitive as fukk then. Like no real advancements in technology happened in that span?
No. It happens about 170 years ago.
Its goes Dany/Viserys/Rhaegar (our show's timeline) -> Aerys II (the Mad King) -> Jaehaerys (forces Aerys to marry his sister to birth Rhaegar/Jon/TPTWP because of a vision) -> Aegon V (from the Dunk & Egg books, old ass Aemon's brother who was at the Wall with Jon Snow) -> Meakar (irrelevant) -> Aerys (irrelevant) -> Daeron II (united Dorne with Westeros, Aegon IV thought he was soft) -> Aegon IV (the Westeros version of Henry VIII) -> Viserys (irrelevant) -> Daeron (basically Alexander the Great) and Baelor (basically Moses of Westeros) -> Aegon III (basically the equivalent of James I/VI, son of Mary, Queen of Scots) ->
Aegon II/Rhaenyra (where House of Dragons takes place...its basically a fantasy rewrite of Queen Elizabeth vs. Mary, Queen of Scots)
This show takes place around the bolded.
Its not that far back.
The show takes place in 300 A.C.
The Dance of Dragons happens in 129 A.C. to 131 A.C.
Thats like going from 1400 to 1600 in our history, from the Yorks/Lancasters to James becoming King of England. Not much changed in that period either.
