Heart of the Aspects had this chinese dragon feeling over it.
I believe, Enchanted Fey Dragon will be the next mount in Blizzard Store, like what Heart of the Aspects was before Mists of Pandaria.
"Faerie dragons, also known as sprites or blink dragons, are fey that look like flying lizards (much like a chameleon with butterfly wings). Though not actual dragons, these mystical looking creatures police the Emerald Dream from magic."
So the Enchanted Fey Dragon is leading us to the Emerald Dream world, as Heart of the Aspects lead us to Pandaria, in some sense.
Now many things are said, by fellow members of this forum, as facts about Emerald Dream but..
You cannot use that as facts as Emerald Dream can be shaped to be whatever Blizzard need it to be, in sense of artwork and in sense of lore.
Because in the end, whatever it may be about the Emerald Dream, it has not happen yet. It's in the future, we only know of the past.
What Emerald Dream used to be about, can be something else now.
--- That was ONE theory --
--- This is the SECOND theory --
"After the second invasion of the Burning Legion, Malfurion Stormrage summoned them from the Emerald Dream to help purge the night elf forests of demonic magics and were called into service briefly during the night elves' hunt for Illidan."
So in the end, this Enchanted Fey Dragon has a link to both the Emerald Dream and the Burning Legion.
What do you make of it?
--- Third late theory ---
What if the Burning Legion is inside of the Emerald Dream and wish to use this:
to enter Azeroth?
