1. Hydaelyn cannot be a Primal. Remember, Primals feast off the aether in land. Were Hydaelyn a Primal, our Planet would be one dry husk. Also, who would be summoning her?

2. I would like to believe that Xephlatol will still be an area in 4.0. We already know much about this region, so it would be too great of a shame to instance it only. But yes, I would understand why it would be instance, given our Ixali relations.

3. It is a safe bet that a library is already being set-up in Idyllshire.

4. My best guess is that the title Soul Surrender applies to the Warriors of Darkness. They have always struck me has Warriors of Light who have failed.
