United Hearts: a Story of the Fastest Thing Alive

(This Story will be from the Veiw points of Sonic's Friends and The Spirits of Harmony until Sonic and the others get out of Limbo)

The Chronicles of Mystearica

Miles Prower

Tails had a miniature communicator on his wrist, for keeping in touch with Twilight and the others. Over the past month he'd gathered everything he could about what the girls were doing. They were looking for a library kept by a dragon that was older than Mystearica, who kept a record of everything that happened on the planet. Where a creature older than Celestia would exist, he'd never know.

His computer raised an alarm of sorts. There were six massive energy signatures headed for Mobius. By their readings, even Sonic would have trouble with them on his own. He pulled up a scanner on them, and they were made of various energies. One seemed to be a living dark void. Necromius. The Vacuum was coming.

Twilight Sparkle

Twilight found the ruins of a library that burned down during a dragon war that happened on Mystearica before Celestia could remember. Her search took her far away from her Home in Equestria, now she was in a land where lions were kings. She tried to get through but there was something off about the entrance. It just looked… crooked. She used her magic to straighten it, and it seemed to turn back into a door. When it was standing upright, it was embroidered with jewels of all kinds and some she never saw before. The wood turned red, and the frame turned into fresh quartz.

She opened the door to find a library very similar to the one in Ponyville. Only everything including the books was stone. There was a hearth in the middle of the room, and a blazing fire in it with a greenish blue hue.

Out of the fire came a small dragon.

"Hello, Twilight Sparkle," He said. "I am Acrimon. Welcome to the Chronicles of Mystearica."

Tailspin

"So what this 'Acrimon' said was that the Harmony Goddess is channeled through feelings of great need for broken limits?" Tails said.

"And that Centurion Sonic was one such need," Twilight finished. "Which is all the more reason to help Applejack and Pinkie find their Harmony Goddesses."

"And we need to do it fast, Mobius is in danger," Tails explained what he witnessed back on Mobius involving the Vacuum. The more time they wasted the closer they got to Mobius.

"And Mystearica could be next," Iron Knuckles trotted into the room with them. His statement only made things difficult. Tails had no idea how they were going to stop the Vacuum with six Goddesses, and Sonic gone beyond Super and Hyper forms alone… then Shadow's origin poped into his head.

The Eclipse Cannon. That was the answer.
