The Blossoming Ancient was finally released today! :D It costs $10 and can be purchased from the US or EU Blizzard store. Remember to purchase from the store that caters to your region, as you can only redeem a code for your region.
It came with a lovely little note from Malfurion (Stormrage).
"Even the mightiest of ancients was once a single, tiny seed.Adorable! I can't wait to level up this cool looking guy. :)
In time, this sapling will grow into one of the Cenarion Circle's greatest protectors.
Until then, it will serve as your faithful companion."
And look, according to its foliage, it's still spring. XD Never again will we have to wonder what season it is in WoW. :P
