Before World of Warcraft there was plain Warcraft, the award-winning, genre-defining real-time strategy trilogy. Many players of the MMO have never experienced those classic stories. The next World of Warcraft expansion, Warlords of Draenor, is going to fix that.

"What if those dark days could come again?" asked Blizzard's Chris Metzen on stage at BlizzCon 2013's opening ceremonies. "To forge a brighter future, sometimes you must confront the ghosts of the past" he continued, whipping the crowd into a frenzy before announcing the next expansion set for World of Warcraft, Warlords of Draenor.

We're going time-traveling, folks. Old heroes, old villains, and settings familiar to the players of the original Warcraft: Orcs and Humans and the two games and expansion that followed.

The new expansion feature a new world in Draenor, upgradeable player garrisons, new character models, a level cap increased to 100 and much more. Also worth noting from the trailer, the ability to boost to level 90 and play from there.

We'll have more on this compelling expansion after the Future of World of Warcraft panel later today.

Update: Blizzard has posted an extensive FAQ covering the major features of the expansion. You can read it here.
