The group went deeper and deeper into the catacombs for like an hour; like it was an endless tunnel underground that keeps going. Sonic was still a little weak from anything made of Holy things. He couldn't focus on morphing into a bat.

"Man, I'm not gonna make it" Sonic slumps against the wall.

"You can't give up, Sonic. We're not leaving you here" Amy said, trying to help him up.

"Guys, look at this" Tails called and the group ran to him and found a gate with bat idols on the sides of it.

"Sonic, wake up!" Shadow slaps him hard.

"OW!!!" Sonic winced and saw the door, "What is that?" He asked.

"That's the gateway to the Underworld" Tails said.

"Finally" Sonic sighs in relief.

They opened the gate and found a pass way filled with skeletons. They saw them move a little since they're asleep because their bones are very old.

"Don't be afraid, Ames" Sonic said.

They went deeper until they came to the guard of the Underworld, "Is that the Grim Reaper?" Amy asked.

"Daughter of the Grim Reaper" The female hedgehog reaper said. She unveil her hood to reveal herself as a pink hedgehog but with white skin, "The name's Rosy"

"Okay, Rosy. Tell us how Scourge escaped from the afterlife" Sonic said.

"Oh, you mean that heartless green vampire? Real simple, someone dripped blood on his remains and he regained flesh and blood again" Rosy explained, "His soul escaped from my river styx. Souls never leave the Underworld"

"Then you must have missed his" Sonic said.

"Not exactly. He has been dead for over 400 years and he could not escape. 400 years later, someone resurrected him from outside the world and his soul escaped the river" Rosy rolled her eyes.

"Do you know who resurrected him?" Silver asked.

"I don't know. But all I know is that Scourge is out for revenge. His soul said, 'I'll have my revenge' and left the Underworld" Rosy said.

"Then we'll find out who resurrected him" Sonic said, "And also, he's after the other half of this" He showed the vampire heart gem.

"Oh, I see. I knew he would try to get that. Good thing my dad kept it safe in his office" Rosy said.

"Then that means he's coming for it too" Sonic said.

"We need it to prevent him from getting his hands on it" Amy said.

"I'll take you to my dad's office" Rosy said, allowing them to go on a bridge made of old wood.

"One at a time" Sonic went first. After Sonic went Tails, then Shadow, Amy, Silver, Rouge, and Knuckles.

"So your dad is on break or something?" Shadow asked.

"Yup, he's visiting Hades in Greek for a week. So he left me in charge" Rosy said.

"Okay" Shadow said.

Soon enough they arrived at a house where the door had handles with skulls on it, "Does the Underworld always have skulls everywhere?" Knuckles asked.

"They represent those who died and their remains" Rosy said.

"Oh, right. Figures" Knuckles shrugs.

When they got inside they saw a desk with a list of those souls that has been taken into the underworld, those who has not reached their end of lives or even died by sickness yet were not crossed.

"Wow, your dad sure knows how to stay organized" Sonic said.

"Say, what happens if a resurrected person dies again?" Amy asked.

"Not that I know of. If Scourge dies again I'll be dealing with him for escaping the Underworld" Rosy said.

"In other words you keep his soul imprisoned" Sonic guessed.

"Exactly" Rosy said, "Now let's see when it was that Scourge came out of the Underworld" She sat on the chair to check, "Ah, he escaped the Underworld 2 weeks ago by someone with dark magic and drops of blood on his corpse" Rosy said.

"And his soul was freed as well as we said before" Sonic said.

"So this someone who brought him back from the dead is probably a dark witch" Rosy said, giving them the other half of the vampire heart gem, "When you find him, kill him"

"Okay, and I promise I won't hesitate" Sonic said and puts the half heart gem in his pocket.

"So how do we get back?" Silver asked.

"Allow me" Rosy took out the Scythe and slices open a portal for the group.

"Whoa, that's new" Sonic felt surprised by this.

"Get into it" Rosy said.

"Thanks for the help" Amy said.

"You're welcome. Now get going" Rosy said and the group gets into the portal.

Somewhere else, a green vampire hedgehog was sucking blood from a woman while his accomplice watched. A female red vixen with a black robe was waiting for him to be done.

"Scourge, how much do you need?" She asked.

"Enough for me to give me strength" Scourge said.

"You're undead. That makes you a zomb-pire or whatever" She rolled her eyes.

"I was only revived thanks to you Fiona" Scourge said and wipes the blood off his mouth, "And the more blood I get the more I feel alive"

"I knew that. But don't forget, the world has changed centuries ago" Fiona said.

"Eh, I get used to it" Scourge shrugs.

"And what will you do once you have both halves of the vampire heart?" Fiona asked.

"With it I shall make humanity and all mobians my slaves" Scourge said.

"So evil" Fiona chuckled.

"And I'll spare you of course" Scourge smirked.

"How sweet of you" Fiona teased.

"No worries. And now we need to find the halves at once. That gargoyle bat took the first half from me" Scourge said.

"But as long as you got me I can find it through this crystal ball" Fiona said.

"That thing? I thought it tells the future, not the present day" Scourge scoffed, "I once used that to find out who the future king is but I couldn't kill him"

"Just in case" Fiona rolled her eyes.

"Fine, as long as it's telling the real truth" Scourge said.

"It never lies, sweetie" Fiona said.

At the Vampire castle, Sonic and his friends showed Manic and Sonia that they got two pieces of the vampire heart, "Now, shall we put them together?" Sonic held up both halves.

Sonia and Manic nods and then they saw the halves join together and then repairs itself like magic. But nothing else happened.

"Now it needs royal blood to fill the gem. We haven't had any royal vampires here for centuries" Manic said.

"Perhaps we should invite them to a gala. Like old times" Sonia suggested.

"Good idea" Sonic said.

"Uh, Sonic? You're gonna need a date" Shadow smirked.

"Nuh uh!" Sonic refused.

"Then I guess she should be my date if you don't mind" Shadow chuckled and tries to take Amy but Sonic hissed in anger.

"DON'T......YOU......DARE!!!" Sonic's green eyes went red when he's angry.

"Sonikku don't!" Amy ran up to him and pets his quills to calm him down.

Sonic's growls are soon replaced by purrs but to his embarrassment his friends watched.

"Aww....that's just adorable" Sonia awed.

"SONIA!!!" Sonic screamed.

"What? I can't help if it's too cute" Sonia chuckled.

"It's just a dance that's all" Manic said.

A while later, Sonic was dressed up for the gala; he had a small golden bat badge on his coat, "Man, I know she's not gonna like wearing that Victorian dress" He gulps and heads out from his old room to meet up with her.

"Amy, are you ready?" He knocked on the door.

The door opens and there stood Amy in lavender Victorian dress, "Uh, hi" She waved shyly.

"Amy.....you look......beautiful" Sonic was stunned.

"Aww...thanks. Seems like I hypnotized a vampire" Amy teased at his reaction.

"Funny" Sonic playfully rolled his eyes, "May I" Sonic held out his hand like a gentleman to her.

Amy takes his hand and they walked out to join the others at the gala.
