Thexerronn

I'm pretty sure that Brandon didn't want to get rid of the information that someone who was killed by a Shard Blade could be revived. In the revised WoR, Szeth died from being thrown into a rock or something, while as in the first edition, Szeth was killed by Syl. The difference between the two versions being of how Szeth died, and the circumstances under which he was revived.
