Those apes the size of giants sounds like Gigantopithecus, which given the very few fossils (mostly teeth) that have been found is estimated to be at least 9 feet tall (maybe as much as 12 feet) and weighing 660 pounds which would make it 40% bigger than a male gorilla. Gigantopithecus' closest living relative is the orangutan according to amino acid protein testing of the teeth in 2019.
Thanks for including my comment about the Tall Trees in the Summer Isles! Also thank you Ashaya for informing us the Siwa Oasis is named after JoJo Siwa 😂😂 it is known
in relation to the first part of the video, what would people from the east say about stories of Varamyr Sixskins in comparison to stories about lizard people or people wearing lizard skins. it seems like there could be something equally as exotic going on there
