Ephriam Vectus

Ephiram Vectus is the ultimate boss of the D&D campaign that inspired the animated series.

Ephiram Vectus is an Eladrin, at least 1000 years old, and hailing from the Feywild. He was exiled after he and his (now deceased) master voiced distain for Humans, who he believed to be reprehensible creatures for diluting the pure blood of Eladrin to create Elves and Half-Elves. Consumed by racial pride, he seeks to take over the kingdom of Velkrave with an ever-growing army of the undead.

The party becomes aware of his existence over time, and slowly formulates a plan to confront him in his own dominion - the Shadowfell, an echo of the material world in the far-flung future, a post-apocalyptic waste. Long before they confront him, they must confront his hierarchy of loyal apprentices, all of whom are incredibly powerful mages in their own right.
