Erebus is a malevolent Cloud Demon whose intention is to devour everyone's shadows to make himself more powerful. He met Knightshade in the village Grayvale one day and promised he will boost his career and make him a star.The demon indeed drew almost the entire village to Knightshade's next concert, stealing all of their shadows, including that of Night Shade's mother, and used them to turn himself into a powerful cloud of magic.
Since then, Knightshade has toured to increasing success, stealing ever more shadows for Erebus, hoping to keep his own shadow long enough to figure out a way to stop Erebus. While hunting for shadows, Erebus calls to Megan to come out of hiding, and she steps up, announcing that she has a surprise for him.A vast army of Flutter Ponies, brought by Molly and Lofty, fills the skies, circling Erebus and blasting him with their Utter Flutter. Unable to withstand the onslaught, Erebus grows smaller and smaller, and the shadows he contains fly out, seeking their original owners, both he and Zeb were placed in prison.
|“||His hunger for power is endless! And I'm forced to help Zeb supply him with more and more shadows. If I don't help him, he'll steal my shadow, which would end my career. But worse, it would mean I'd never have any hope of restoring Grayvale!||„|

He promised Knightshade he would make him a star and succeeded, using the singer's popularity to his advantage to siphon the shadows from anyone who came to his concerts, even children.
His minions were extremely loyal to him but whenever they made a mistake or failed at a task, Erebus didn't mind kicking them around for their failures.
Powers and AbilitiesGenius Intelligence: It was potentially him who invented the magic satchel which is able to steal other creatures' shadows.
Shadow/Magic/Soul Absorption and Corruption: With the exception of Knightshade's mother, everyone who had their shadows stolen by Erebus became bitter (and skinny and weak), almost as if their souls, emotions and general strength had been stripped off their bodies, which is more or less what is implied.Atmokinesis: As an elemental creature, Erebus possesses the power to control the weather as he pleases, from creating small tornadoes and blowing powerful currents with his breath to shooting lightning bolts from his fingertips.
Shapeshifting: Being a living cloud, Erebus can make himself solid or gaseous at will or morph into various forms (and even develop a foot) and fit through any gap, as well as darken his cloudish appearance so that it looks as though he's wearing a robe. Additionally, he grows bigger the more shadows he consumes.
Magic Mirror: Erebus possessed a magic mirror in his mansion, from which he can observe events going on outside or communicate with his minions.
MinionsErebus had four henchmen (not counting Knightshade), one being Zeb, an anthropomorphic Zebra, and the other three being rat thugs from a mice village Erebus already stole shadows from, who worked under Zeb as well.
Zeb acted as Knightshade's manager according to Erebus' plan, who had put him there to steal shadows from him while he stayed at his mansion, a task he carried without second thought, unlike Knightshade, as Zeb was nearly as despicable as Erebus himself. The rat thugs chased after the ponies and captured them when they tried to escape. They were all captured and imprisoned by the people of Grayvale and the Flutter Ponies after Erebus was defeated.
- He's the second major antagonist after the Smooze that required the help from the Flutter Ponies to defeat, not counting Queen Bumble who attacked the Flutter Ponies directly and wasn't as big of a threat (without the sunstone).
- Erebus very evidently served as one of the main inspirations for Tirek (aside from Tirac himself): Other than common tropes like being power hungry and betraying a henchman that is no longer useful to them, both start out very weak and cloaked, trick a good character into helping them get stronger, and as they get stronger (which both do via consuming shadows/magic through their mouths) they increase in size as well. And once they are defeated, all the power they stole is stripped away from them and the two are imprisoned instead of killed. Additionally, Tirek's horns in his later forms sometimes resemble Erebus' spiky eyebrows.
