The Dire Lands (The Greystone Chronicles #2)

Jupiter Tech's headquarters, Olympus, has been attacked. Lives have been lost in the real world. Alexander and friends must now thwart the servants of the Dark One both in and out of the game.

With a few new allies, the Greystone Guild moves out of the noob zones to take on the challenges presented by the ruins of Dire Keep and its inhabitants. They must conquer, rebuild, and defend the Dire Lands against attacking forces.

The players (and Fibble) must now overcome tougher dungeons, and more dangerous foes. Even betrayal by one of their own!

This is the second book in the Greystone Chronicles series. I recommend reading the first book before this one.
