Kairos Fateweaver

Kairos Fateweaver is the most powerful Lord of Change in the service of Tzeentch, known as his Oracle.

While Tzeentch knew everything there was to know about the past and present, he was unhappy that he couldn't get a perfect view of the future. In an attempt to overcome this issue, he went to the Well of Eternity at the center of reality. However, because Tzeentch is kind of a massive bitch, he didn't want to go in himself and sent his Lords of Change instead. The problem: none of his servants ever returned.

Fed up with this, Tzeentch eventually grabbed Kairos and tossed him into the well. He survived, but only just, emerging with two heads and a bad case of insanity from his knowledge of the future. Now, when asked a question about the future, one head will tell the truth and the other an equally plausible lie, meaning that his predictions are somewhat difficult to interpret.
