Zekvir's Lair is a delve in World of Warcraft: The War Within with one of the most difficult pieces of solo content since the game's Mage Tower challenges.
The ultimate boss of the game's new short, soloable-dungeons, or Delves, Zekvir has a small mountain of health (195 million at the top difficulty) and uses mechanics that can be exceptionally challenging if you're not ready for them. You can tackle him alone or with friends, on "?" difficulty (yes, that's just a question mark) or the tougher "??" challenge level. Killing him on "??" solo earns you the Void Delver's Dirigible mount appearance, one of the most prestigious in the game at the moment.
