In speculating at Dany’s future, we are obviously guessing at whether she will sit the Iron Throne in King’s Landing. While I think this unlikely for several reasons, I think it is significant that we are told multiple times that the doors in the Red Keep and King’s Landing are bronze:
- “Eddard Stark rode through the towering bronze doors of the Red Keep.” GoT
- “Across the city on the hill of Rhaenys stood the blackened walls of the Dragonpit, its huge dome collapsing into ruin, its bronze doors closed now for a century." GoT
- “Not until the pages had closed the great oak-and-bronze doors behind him did Sansa hear sounds again.” GoT
- “Courtiers filled the gallery while supplicants clustered near the towering oak-and-bronze doors.” GoT
- “The long hall went on and on and on, with endless doors to her left and only torches to her right. She ran past more doors than she could count, closed doors and open ones, doors of wood and doors of iron, carved doors and plain ones, doors with pulls and doors with locks and doors with knockers. Drogon lashed against her back, urging her on, and Dany ran until she could run no more. Finally a great pair of bronze doors appeared to her left, grander than the rest. They swung open as she neared, and she had to stop and look. Beyond loomed a cavernous stone hall, the largest she had ever seen. The skulls of dead dragons looked down from its walls.” CoK
So, if bronze doors are not for her, where are the red doors other than the house in Braavos? In searching through the books, of all the descriptions of doors, there are only two doors that I found that could be described as red.
We get a description of the doors to Riverrun as being made of redwood, which could be viewed as red, but I don't think Riverrun makes much sense. So where else is described to have red doors? Where else could be home?
- “The doors to the Great Hall were set in the mouth of a stone dragon. He told the servants to leave him outside. It would be better to enter alone; he must not appear feeble. Leaning heavily on his cane, Cressen climbed the last few steps and hobbled beneath the gateway teeth. A pair of guardsmen opened the heavy red doors before him, unleashing a sudden blast of noise and light.” CoK
From Dany’s constant longing for “home” and the frequent imagery of “the red door,” I think we are given contextual clues that Dany’s final destination is Dragonstone. I think she is going to make an appearance at King's Landing, but just like the door in the House of the Undying Ones, it will not be the right path for her. She will find her home at her birthplace, with heavy red doors.
