With just one season left of Game of Thrones, fans are already turning their attention the various spin-offs that could potentially head into production at HBO once the show wraps up. Not much is known about what connection they’ll have to Game of Thrones itself, but considering the sheer scope of George R. R. Martin’s world, the choices are endless.

What we do know is that the four spin-offs that are currently in development will take place before the events of Game of Thrones and won’t feature a single character from the show. That pretty much rules out a popular theory that one of the spin-offs will chronicle the events leading up to Robert’s Rebellion, because well, you can’t have Robert’s Rebellion without Robert Baratheon (and Ned Stark for that matter).

So where does that leave us? Jane Goldman—currently working alongside George R. R. Martin on one of the spinoffs—is here to shed some light. While speaking to IGN, Goldman let slip that her show will be “recognizable of a past event” for those familiar with Westerosi lore.

Hmmm. While that doesn’t narrow down the field enough that we can accurately deduce what she’s referring to, it does present us with an interesting option. The downfall of Valyria remains central to Game of Thrones’ overlal mythology. Before it became a chapter in the history books, Valyria was a great empire and the ancestral home of the Targaryens. It was eventually destroyed by a devastating event called “The Doom of Valyria” and reduced to the ruins we saw Jorah and Tyrion sail through in season five.

A show chronicling the Valyrian Empire at the height of its powers and then exploring what led to its downfall would be catnip for Game of Thrones fans and writers alike. Goldman also hinted that her show would include some of the magical creatures that fans have come to expect from Martin’s works. “Yeah, I mean those are things that exist in the universe that George has created and it’s certainly — that’s an aspect that I love so, umm, yeah, I’m sure there’s an element of that in anything that’s being developed but, yeah, that’s — I guess so, yeah. I feel like I’m saying way too much! I can say absolutely nothing.”

We should note that Valyria is also the original birthplace of dragons, so make of that what you will.
