Tails drops off Sonic in the snowstorm since the storm is too intense to get to the factory by air but to keep warm, Amy made him a kneaded scarf and he sped off towards the factory where Eggman plots his next move to conquer the world.
Sonic battles many of Eggman's robots and reaches the factory.
at the entrance, the factory transformed into a giant mech and the two battled, only this time, a bottomless pit formed in the midst of the battle and Sonic who was in his super form, was dragged into the darkest and deepest abyss by some tendrils of the Spectral World.
"Um, doctor, I think we gone and done something very terrible," said Orbot.
"Yeah boss, we awoken something very dark and well gloomy," said Cubot.
"I shouldn't guess, the Eternal Nightfall has arrived as he predicted," said Eggman.
"He, who's he," said Cubot.
"Yeah, do you know him," said Orbot.
"Father," said Sage.
"Sage, I'm sending you down there to rescue Sonic," said Sage, no organic lifeforms can resist some abyssal liquid sustance down below, it's far too dangerous for anyone to enter," said Eggman.
"Of course Father," said Sage.
Then Sage enters the abyss.
Through the Abyss, Sonic began a drastic change, his muscles and bones became exposed while his fur color turned light blue, his quill became two sets of quill-like flaps, his jaw was completely gone leaving only his upper part of his mouth which causes him to use the now blood red kneaded scraf as a cloak and mask to hide his hideous disfigurement, his eyes lacked pupils and left with nothing but white glows, and his gloved hands were torned and lacking skin thus becoming bone claws.
This transformation turned Sonic into Wraithic, a hedgehog-wraith hybrid.
Then a voice appears, calls him Hades, the King of the Spectral World, and said, "Wraithic, you live, tell me, how does it fell to live as a Wraith, a servant of my will, feed on those lost souls and I shall reward you your freedom."
But Wraithic, who also lost his voice in the process, could be believe a word Hades was offering but he needs to find a way out and save the world once more, but the question is, how?
