Swiftmane

Swiftmane is a level 21 elite rare mob zhevra found just above Ratchet in the Barrens.

As his name implies, he runs at ridiculously fast speeds, he can easily outrun a normal ground mount and stand up against Epic one, so for those with not epic land mounts, you just have to wait until he comes back from his tour around the prairie. Swiftmane cannot (As all zhevras) be tamed as a hunter pet.
