Ahead of Blizzcon, Blizzard Trademarks "Eye of Azshara"

With just days to go before BlizzCon 2014 begins on Friday, some of World of Warcraft and Diablo developer Blizzard Entertainment's surprises may have been revealed thanks to the discovery of a pair of trademarks.

PCGamesN reports that Blizzard Entertainment recently filed a trademark for something called "Eye of Azshara." As the site points out, Azshara is known from Warcraft lore as the "elven queen who used the Well of Eternity to summon Sargeras and the Burning Legion to Azeroth."

Could Eye of Azshara be the next World of Warcraft expansion? An announcement at BlizzCon--before the Warlords of Draenor expansion is even released--would seem unlikely. At the same time, however, Blizzard hasn't shied away from saying it's already planning World of Warcraft expansions beyond Warlords of Draenor.

Another possibility is that Eye of Azshara is the name for an upcoming expansion for Blizzard's free-to-play collectible card game, Hearthstone: Heroes of Warcraft.

In other Blizzard trademark news, the company also recently filed a trademark for something called "Overwatch." According to its official description, this trademark covers all manner of printed material, including strategy guides, comic books, and novels. It also covers clothing and toys, but not video games.

BlizzCon kicks off on Friday, November 7 and runs through November 8. GameSpot will be on the ground at the show bringing you all the news as it happens. Be sure to keep checking back on Friday and throughout the weekend for news from the show.
