The Rotting Hoard

It appears in the alternative timeline Reign of Dragons.

History
When the world was conquered by the dragons and the gods vanished, the dragons took hold of their powers, including necromancy. One such dragon in particular stands out in practicing the Immortal Empire's lost art, the Emperor of Corpses. The Traveler travels to its nest and confronts it for good, however the creature doesn't give itself easy.

After the fight, the world has ended up one dragon less, but would it change the tide of events?
