Does the Death knight have a mount?

The death knight does not start with a mount, but early on receives a quest which requires him to 'steal' a horse from the scarlet crusade, after which it is slaughtered and ressurected as a deathcharger. This is a 100% speed epic ground mount, and costs no money for training or the mount itself.

There is also a "winged steed of the ebon blade" available at level 70 once you have purchased your flying mount training. The current model for the winged steed is that of a skeletal gryphon.
