That Feldrake looks very cool!!!
The symbol on it's head and saddle is from the Burning Legion (NOT Darkmoon Faire!!).
That makes this mount actually so interesting. Check it:
But where can it be looted......?

It's clear now.
It is definitely an item from the Trading Card Game. From an expansion called Timewalkers: War of the Ancients.
