Apparently, the second set of the Khans block has been relieved: Fate Reforged! Is that Bolas I see in the background?
Based on what I’m hearing from Pax, the story is this: Sorrin and Sarkhan go back in time to stop Bolas from killing Ugan, the spirit dragon! I’m going to assume they succeed, and the third set is all about the new present they’ve created by changing the past. Neat!
