I have been admiring the crane pets I have seen in pics from the MOP beta.
I think they are gorgeous creatures and am super excited about the Riding Crane Mounts.
You must be Exalted with Golden Lotus faction in order to buy the mounts.
They cost 3,000 gold.
There are 3 different Riding Crane Mounts:
Reins of the Azure Riding Crane
Reins of the Golden Riding Crane
Reins of the Regal Riding Crane
