Warcraft: Shadow Wing

Sinopsis

Following their victory in the Ghostlands, where they thwarted the undead Scourge's attempt to seize the Sunwell's energies, the blue dragon Tyrygosa and the human paladin Jorad Mace find their journey far from over. They are drawn into the Dark Portal and transported to the shattered world of Outland. There, they encounter the enigmatic, incorporeal nether dragons. Unbeknownst to them, the ruthless Ragnok Bloodreaver, an original death knight from before the Second War, observes their every move, harboring sinister plans for the nether dragons that could imperil all of Outland, including Tyri and Jorad.
