It's every good Erudite's worst nightmare! "Erudin Burning" is one of 13 zones being introduced with the House of Thule expansion in October. Here's a sneak peek from EQLive:

Erudin Burning

The learned Erudites aren’t proof against the nightmares plaguing Norrath.  In this zone, meant for adventurers about level 90, Erudin’s fears are made real.
 
The outcast of Erudin, the Heretics, have taken over the city and are laying waste.  The citizens are fighting desperately to preserve the shining walls of Erudin, but the battle isn’t favoring them.  The Deepwater Knights fight valiantly to save their home against nearly overwhelming odds.
 
Terris Thule, the goddess of Nightmares, is personally watching over this particular horror and her minions can be seen around the zone fueling the dream.  Experts in their craft, Terris and her minions give the Erudites, just enough hope to keep them in the dream, but never allow them to win.
