'GoT prequel will have the Starks, but no Lannisters'

Los Angeles: 'Game of Thrones' creator George RR Martin has teased details from the much-anticipated prequel of the hit HBO series, saying Westeros will be populated with the Starks and White Walkers.

The Lannisters will be missing from the continent as the Casterlys, after whom Castlery Rock is named, will be introduced.

"The Starks will definitely be there. Obviously the White Walkers are here or as they're called in my books, The Others and that will be an aspect of it. There are things like direwolves and mammoths," Martin told Entertainment Weekly.

The writer, who is also attached to the spin-off as an executive producer, said Westeros is divided into roughly 100 kingdoms in the prequel.

"We talk about the Seven Kingdoms of Westeros; there were Seven Kingdoms at the time of Aegon's Conquest."

"But if you go back further then there are nine kingdoms, and 12 kingdoms, and eventually you get back to where there are a hundred kingdoms petty kingdoms and that's the era we're talking about here."
