GameSpy has published a two-page preview of the armies that make up the Chaos faction in EA Mythic's Warhammer Online: Age of Reckoning. The Sorcerer of Tzeentch:
So you ask yourself, what do Sorcerers of Tzeentch do? They fly around on disks with great big spikes that glow and they grab energy from out of the air and they can turn it into fire and lightning that they can throw around. They're resplendent in their enormous fluted shoulder pads and helmets in the Tzeentchian colors. He's not like an old-fashioned wizard: bloke, beard, hat, stick. As for his gimmick? He's on a flying disk, armored, claws, and throws lighting bolts at you! Will you shut up?
Chaos is fantastic. It's been the one area that the artists have been mad on ... After working relentlessly on Dwarves and Greenskins, you really do need a bit of breathing room. You need a bit of Chaos corruption in your life. It makes you happy.
