In my head-canon, I have come to believe that Abeir was actually where the Sauriel were from. And when Abeir merged with Toril in 4e, the Dragonborn and a few of the Sauriel ended up on Toril.As much as I liked Azure Bonds, it felt a lot like a retread of the computer game, but with a different protagonist (even though, technically, it's a prequel novel--I played the game before I read the book). I don't have strong feelings about the second book, but man, did I love Song of the Saurials. I think I would rather have had saurials added as a core race to D&D than Dragonborn. Plus, thanks to Reaper Bones IV, I actually have quite selection of dino-folk minis (both fantasy and sci-fi).
