“There’s been a sea change in Hollywood. They realize there’s a fan base out there that wants constructed languages,” said Matt Pearson, a linguistics professor at Reed College in Portland, Ore. He created Thhtmaa (pronounced tukhh-t’-mah), the language of termite-like aliens in the short-lived NBC series “Dark Skies.”

“Game of Thrones,” based on the best-selling series of novels “A Song of Ice and Fire” by George R. R. Martin, may be the biggest television showcase for an invented language. The books, which primarily follow feuding kingdoms in the fictional land of Westeros, had a scattering of Dothraki words, but the show’s executive producers wanted a fully formed language.

This is the sort of show where gruff men in wolf cloaks mutter ominously that “winter is coming”, exiled princelings bitch about their lost birthright and there is much discussion of prophecies of old. Yet even if that kind of thing usually makes you run screaming to the nearest crime drama, Game of Thrones is worth sticking with.

Don’t be put off by the huge number of people in the cast, just sit back and enjoy the clever way in the tale unfolds. Essentially the story of Ned Stark (Bean) and his fateful decision to help his old friend Robert Baratheon rule, Game of Thrones is also about the evil that men do in the name of power, the lengths that people will go to hold on to a throne and the corruption that ultimately corrodes a kingdom.
