I tried to get up in to this area just a bit ago with the mountain climber trainer, and guess what? Ran right up a invisa-bliz-wall. Mind you those ****ing things go way the **** up. 20 second fall FTL =\Grim Batol as a New Zone
There is some implication in the novel Day of the Dragon that Grim Batol may be more than just the fortress in the Wetlands, and may also include a zone(also known as Grim Batol) east of the fortress that the Hill Dwarves take back after the second war. In the Eastern Kingdom's map in WOW there is an unfinished zone to the east of the Wetlands and Loch Modan. In the Warcraft RPG that area is called Grim Batol.
But, that wall peaked my interest. Big time.
I need some other peoples input you should all tell me what you guys know about it. PLEASE!
