I just want to toss out one last block of speculation, my stab at the backstory for these guys. I'll include some carriage returns in case you'd rather not know.
This story is leafy, makes post-WHOA sense and gives them reason to hate the Blood Elves and Forsaken. As well as a reason to go to Outland.
Edit: Teske beat me with the WoWguru quote! I like mine better :P
Quote:What we're seeing are (for lack of a better term) the "Children" of Archimonde and the World Tree. Parts of Archimonde and the Nordrassil are still on Hyjal, after all. The tree which made the Night Elves immortal and grew from a remnent of the Well of Eternity has given these new beings their intelligence and existence but these New Eredar pay a high price; they forever feel the pain of that cataclysmic event and in spite of despising demonic energy, they feel a constant pull on their soul.
Just like some alcoholics know they can never a drink...the NewEredar sought out the Silver Hand to teach them disciplines of the Light, hoping it would help control their thirst for evil. Oh, and they're headed to Outland because they understand better than anyone else the danger the Legion poses.
