When Twilight and the others showed up at town hall, after being rounded up by Rarity and the Cutiemark Crusaders, it was too late. Sombra had covered the building in crystal, keeping anypony from going in or out. Celestia and Luna were informed of the situation and were rewriting the meaning of haste to arrive at the scene. Everypony had escaped except for Applejack, who stayed behind to watch over Nyx, Teotle, and Day Dreamer, still under Sombra's spell.

"This is bad." said Twilight. "This is really really bad."

"How in Celestia's name could this happen?" Rarity asked. "I thought we banished Sombra with the elements.

"Does it matter?" Rainbowdash asked. "If you ask me, all I care about is how to kick his..."

"It matters, Rainbowdash." Fluttershy interrupted. "He shouldn't have come back so soon after we fought him only a week ago."

"You didn't let me finish." Rainbowdash Protested. "How can we beat him if we can't get to Applejack to complete the Elements of Harmony?"

"You're both right." Starlight interjected. "Do you remember hearing about the malfunction the Arc had two days ago?"

"Yeah, why?" Pinkepie asked.

"Well... I think that is because Sombra did something to it when he attacked Teotle during our last fight." starlight explained. "The Arc is designed to disassemble and reassemble matter and is able to generate and manifest Spirit energy, so if my theory is right, then..."

"Sombra put part of his spirit into the Arc?" Twilight asked.

"Yes." Starlight answered. "We've been tricked into making the key component that Sombra needed to make a brand new body."

"But, how can he just split his soul like that?"

"He didn't." Celestia said, climbing from her chariot with Luna by her side. "The Teotle has told us much of the Arc's development, so I think we know what he did."

Then Luna said, "Much like how Nyx was born to be a copy of Nightmaremoon, Sombra probably used the Arc to make a copy of himself. When he did that, The copy must have overpowered the Arcs core to take control of it and its functions."

"All Sombra needs to do now is rebuild his old physical from." Celestia said, staring at the crystal barrier.

"Well, how do we stop him?" Spike asked nervously.

Luna frowned and said "I'm afraid we can't do anything but pray that Nyx and Teotle will prevail."

"Why?" Twilight asked. "Why can't they just be safe? Why do the two of them always have to do things like this alone?"

"What makes yum think they're alone?" asked a familiar female voice from the distance.

Everypony turned around and saw Teotle's sisters, Scarlet Rose, Fracture, Ill Heart, and Empty Heart, along with his brothers, Brimstone, Ulcer, and Coma. All of Teotle's siblings had come to aid the others in defeating Sombra

"You're all here?" Twilight asked. "How, why?"

"Scarlet wrote to us, telling us about Teotle's science fair. "Fracture answered.

"We wanted to make a surprise visit and see what he's been working on." Coma added.

Ulcer then said, "But the train tracks that connect Equestria to home was still under construction. And on top of that, our twin sisters stole my snacks during the trip here."

"DID NOT!!!"  Ill Heart and Empty Heart said together in unison.

"Oh shut up." Brimstone grumbled. "It's bad enough that I had to tag along to save my idiot brother, but I shouldn't have to deal with you foolish cubs."

"Cubs?" Coma asked, inspecting the sharpness of his battle-axe. "You're only a year older than me and Ulcer and Fracture's taller the you."

"I'm the oldest between the eight of us." Scarlet said with grin. "So, technically speaking, I out rank all of you."

Brimstone growled and said, "Why you..."

"Enough!" Luna shouted. "Excluding Scarlet Rose, you all share a part of your fathers power, yes?"

"Yeah." Fracture answered.

Luna continued and said, "If you are all here, then you should be able to use that power to break through the barrier. Am, I Wrong?"

"No, we can do it." Empty heart answered.

Ill Heart then added, "However, since Sombra has that Arc thingy, it will take a while."

"Especially without Teotle." Empty Heart continued.

"Just tell us what you need." Celestia said.

"We need a lot of space to work." Fracture said, signaling everypony to move to a safe distance. "And we'll need something to use as a conductor."

"I know just the thing." Applebloom said, pulling out a potato Battery from her school saddlebags. "I made this as a backup in case the original project got eaten or something."

"Perfect." Fracture said with an approving smile.
