There's one detail you missed. In The Eye of the World the voice is ITALICIZED, but in Lord of Chaos when the Dark One speaks its voice is simply ALL CAPS. I always took that as more evidence that in EotW it was not the same voice, but the other deity, the Creator.

Also, I assumed the reason the Forsaken felt ecstasy (as well as pain) at being spoken to by the Dark One wasn't because its voice was inherently nice to listen to, but because they were sworn to the Shadow and worship evil, its voice has that effect. Maybe Light-sided people would just feel agonized at having that voice in their skull.

Looks like he's on his way to the Pit of Doom!

I first discovered Dragonmount when RJ was writing his blog, and since then I've been hooked. I loved that we were able to get answers to questions directly from the Creator's mouth. Thanks for all the hard work you guys do to keep all of the fans up to date on the latest WoT news! The degree of interaction that you folks have had with both RJ, Brandon, Harriet, and Team Jordan is impressive. Keep it up!
