The First Game of Thrones Spin-Off Will Go Into Westeros' Deep Past

HBO has ordered a pilot for the first of its five potential Game of Thronesspin-offs and will travel back in time deep into Westeros' complicated history.

The potential new series will venture thousands of years into the past according to the official description reported by The Hollywood Reporter. The vague logline reads, "Only one thing is for sure: from the horrifying secrets of Westeros' history to the true origin of the White Walkers, the mysteries of the East to the Starks of legend... it's not the story we think we know."

The "true" origin of the White Walkers is probably perking up the ears of Game of Thrones theory nerds right now. As far as fans -- both book and TV alike -- are aware, the White Walkers were created by the Children of the Forest before the Age of Heroes to protect the Children from the First Men. As you could expect, White Walkers wanted more for themselves than to be controlled body guards, so they broke free from the Children's control. They eventually tried to invade Westeros during the longest winter on record, 8,000 years before Robert's (Mark Addy) Rebellion which was the pre-cursor event for the original Game of Thrones series.

What this spin-off is proposing is that there may have been a more sinister reason for the Children of the Forest to create the White Walkers and a deeper reason for them turning into the most feared creatures in Westeros. Not to mention, we'll always tune in for more Starks. Bring on the direwolves.

Kick-Ass and Kingsman: Secret Service scribe Jane Goldman is on board as showrunner using material from George R.R. Martin. Bloodline co-creator Daniel Zelman also joins the producing team, but Vince Gerardis is the only current Game of Thrones producer listed by THR. Current Game of Thrones leaders David Benioff and Dan Weiss are not involved in the spin-off as they've been busy producing the final season of the epic series.

The biggest question now is: How many ice dragons will there be?

Game of Thrones returns for its final season in 2019.
