In fact, we’re thinking Martin could’ve slipped in another clue about Cogman’s show in his announcement, as well.
In the post, the author calls Cogman the “Keeper of Lore” and the “Prince of Dragonstone.”
If [David Benioff and Dan Weiss] have been the kings of Westeros for these past seven seasons, Bryan Cogman has surely been the Prince of Dragonstone.
Yep, that Dragonstone …
Dragonstone is the ancestral seat of House Targaryen. Since Martin calls Cogman the prince of it, perhaps we’ll see a Targaryen storyline come to life.
If so, we’re thinking we could see when the Targaryens originally left Valyria, just years before The Doom destroyed the entire city (which is still largely a mystery), or, even more likely, fans might finally get to witness Aegon’s Conquest, when Aegon Targaryen conquered Westeros with his dragons.
Coincidentally, HBO just released a video from the Season 7 DVDs that tells the “History & Lore” of the Targaryens and Aegon:
In any case, Martin offered one other teaser: that we could see one of the prequel shows on air as soon as 2019 or 2020.
There’s no official word from HBO on what series, if any, would actually make it to air and when. However, we’ve previously heard that a new “Game of Thrones” series wouldn’t start until after Season 8 finishes.
There is no end date set for the final season of “Game of Thrones,” but reports say it could debut by late 2018 or 2019. If that’s the case and everything goes well with the prequel scripts, it’s possible that Martin could be correct. In a couple years, we might just have another “Game of Thrones” to speculate about and theorize on.
