There’s a rumor floating around the web that the next World of Warcraft expansion might be titled “The Dark Below”. This is because Blizzard recently filed a trademark for the phrase “The Dark Below” which everyone initially speculated would be the name of the first expansion to Diablo III. However, with the launch of a new teaser site that suggests D3’s expansion is actually called “Reaper of Souls” these leaves everyone wonder if “The Dark Below” might actually be tied into World of Warcraft.

Of course if this does turn out to be the fifth WoW expansion that stirs up even further questions about what the Dark Below even is. This could be a reference to a realm inhabited by demons that are separate from the Burning Legion. Or it could relate to the Ozumat, the final boss in the Throne of the Tides instance who has the subtitle “Fiend of the Dark Below”. Others believe it refers to the core of Azeroth itself which would allow the developers to add new zones without the need for a new world (Outland) or some undiscovered land mass (Northrend, Pandaria).

If The Dark Below does turn out to be the next expansion what would you like to see Blizzard add? A new hero class? Dynamic storylines? New gameplay mechanics? Let us know in the comments below.
