[Glencook-fans] I just noticed something about Water Sleeps

Third paragraph of the first chapter says two of fifty people returned from Glittering Stone to lie about what happened. That's Swan and Soulcatcher. But it also says a third "had come back to retail the truth had ben killed in the Kiaulune wars, far away from the captital." I missed that before. I'm rereading Glittering Stone right now. I haven't run across the name of this person yet. Does anybody remember if we ever find out who it is?
