A couple of months ago, Turbine President and CEO James Crowley when questioned about how Turbines next upcoming MMORPG based on the Drylor fantasy book series which is being designed by Asherons Call's very own Toby Ragaini would fair against specifically World of Warcraft, he responded "Drylor will be the next big thing for the entire gaming Industry. World of Warcraft long-standing grip over the market is about to loosen up".
The Easter-Egg discovery was made last night, March 22nd when a group of friends managed to break into a strange barred room within Stormwind City. Using an Eye of Divinity, a priest, Mends of the Arthas realm, was able to see the two spirits within the room: One of an Orc laying lifeless on the ground named Warcraft, and one of a Ghost named Drylor. This came as a shock, as one of the members who participated in aiding the priest was aware of Turbines future MMO; the WoW forums have since broken out in discussion over Drylor, but Blizzard has been promptly deleting any threads, refusing to comment on the discovery.
