We are talking of course about Heart of the Aspects. You can get it for:
When attacking from the air, it's best to advance from the angle of the sun so as to blind your foes… Or just ride a luminous dragon that glows like a thousand suns. Either way, you're good.
You may have seen the mount already, because it was data mined already, and seems like the assumptions that this is going to be sold on Blizzard store were right...
If you are interested in winning one of this mount do not miss the Mmo-champion and Wowhead contests. Be quick and good luck.
Also, stick around, we might have a few mounts to give here on Wowjuju too.
