Tam said: Thanks. I had to look up the timeline...seemed like a lot longer. But maybe he was just also jaded and bummed out by events happening with Kahvi and Tyldak.
I think it was more a melancholy that set in after the Forevergreen (and let's face it, we were all morose about that one!) when he got back to find Sorrow's End destroyed and traces of Ahdri's spirit in the rock and assumed she was dead.
His adventures with Kahvi and Tyldak happened during the long sleep, before the events of Forevergreen, which could have been decades or centuries before the Wolfriders awoke.
