UnderEquestria

"Sunburst!" Twilight yelled at the orange pony, reading a spell. "We need you to preform the spell now!"

"Ah yes, I kn-know Princess!" Sunburst stammered, obviously scared.

The Mane six were trying to stop the frozen north from covering the crystal empire, with limited success.

"Twi!" Shouted Rainbow Dash - who had just crashed into one of the crystal trees - "We can't stop it! We need to evacuate the empire!"

The crystal ponies were already running, while Princess Celestia and Luna were on their way.

"Cadence, Shining Armour!" Flash Sentry yelled. "We must leave, I have the baby!"

The Mane six ran with the royals, with Starlight Glimmer and Sunburst following.

They reached the train, but suddenly, a magic explosion hit the train, and Flurry Heart fell backwards, back into the frozen empire!

"Twilight!" Rarity spoke, her voice quivering in fear. "We must get Flurry Heart!"

"Starlight, stay here with the others!" Twilight yelled, before the mane six ran after Flurry Heart.

The baby alicorn was laying in the snow, crying.

"Shh shh...." Fluttershy softly spoke, with care in her voice. "We've got you."

Suddenly, Flurry Heart let loose a beam of magic, creating a massive hole in the ground, and the main six fell! The last thing Twilight saw was the smirk of the baby, as it used its magic to place herself onto the train.

The ponies fell for what seemed like years. They only had a vague guess of how far down they were into Equestria's underground.

They saw skeletons of ancient beasts, such as the Cyclops, a tall pony-esque race.

"How far down are we?" asked Applejack.

"I don't know!" Yelled a scared Twilight.

Suddenly, as if Applejacks question had been answered, they crashed into a patch of bright yellow flowers.

"Twilight.....Twilight...." Spinning Pinkies were looking at Twilight. She sat up.

"You took quite a hit!" spoke Rarity, in her soothing voice.

"So, what in the hay is this place Twi?" queried Applejack.

"It looks like UnderEquestria, but that's just an old mares tale...."  Twilight whispered.

"The hay is UnderEquestria?" Applejack said, she was clearly very confused.

"Don't tell me you never heard the tale of UnderEquestria!" Pinkie Pie, who was still spinning around, said.

"Here, I remember it," Twilight said.

"Long ago, there were two major pony races in Equestria. They were called the Monster-Ponies and Ponies.

There was a great war.  The Monster-Ponies lost, but killed all the natural alicorns except Celestia and Luna, and the Monster Alicorns. The Monster Ponies were sealed in the UnderEquestria.  It would take the power of six pony souls to break the barrier that kept them imprisoned."

Suddenly, a strange flower, with a pony face appeared!

"Howdy!" It spoke.

"Uhh... Hello?" Said Applejack.

"I'm Flowey!" Flowey said.

"Ummm... Hello... Flowey. "Fluttershy whispered.

"Well, being formal, my full name is Flowey Heart, but since we're friends, call me Flowey." the flower-pony spoke again.

"Well, all right sugar cube" Applejack said. "Name's Applejack, these are my friends, Twilight, Rainbow, Fluttershy, Pinkie and Rarity."

"You must be new to these parts, you must be confused!" Flowey said.

"Uhh... We are." Rarity said.

"Well, I'll teach you how things work around here!" Flowey said happily. "Ready? Well, See those hearts? They are your souls!"

"Ponies have souls that look like hearts?" Rainbow said. "Awesome!"

"Anyway, these are friend pellets, walk into them!" Flowey created six pellets, out of thin air.

The pellets flew at the Mane six, and hit them, sending them backwards, bruised and bleeding.

"Y O U  I D I O T S"  Flowey spoke, with evil in her tone of voice. " I N  T H I S   L A N D  I T  I S  KILL OR BE KILLED!"

Pellets surrounded the main six, edging closer and closer.

"DIE" Flowey said, laughing as the pellets edged closer and closer.

Suddenly, as the Mane six closed their eyes, the pellets dispersed away from them!

"WHAT!" Flowey said, before a beam of light hit them, sending them flying into the darkness.

A goat lady strode across, the mane six were more wary of her, but still plucked the courage to speak to her.

"You are not going to hurt us, are you?" Rainbow asked, worried.

"Do not be afraid, my child, all of you."  the Goat lady spoke, with a calm voice. "I am Torishy, I look after these ruins."

"Well, hello Torishy, I am Twilight Sparkle, These are my friends, Rainbow, Fluttershy, Applejack and Rarity." Twilight said.

"You are the first ponies to visit in a long time." Torishy spoke. "I will guide you, follow me." She turned and walked.

"Well, what else can we do?" Fluttershy said, before they all started to follow Torishy.

They followed Torishy, who taught them about any traps in the Ruins that were made long ago during the war. They reached a clearing, where a dummy stood. "You must talk to this dummy, it will attack you, but do not attack it, be nice." Torishy said, as the dummy loomed closer.

"Hi, I'm Twilight Spar-" The dummy cut in.

"Yeah I do not care, screw this Torishy I'm out of here." It hopped away into the dark.

Toriel made a sad face, but continued on. "Say, what pie do you like?" She unexpectedly said. "Cinnamon or Butterscotch?

Pinkie suddenly yelled. "Chimmy-Cherry-Changa-PickleBerry kumquat pie obviously!"

"Chimmy Cherr- What????" Torishy said.

"Don't mind her, thats just Pinkie Pie being Pinkie Pie" Rarity spoke, a bit embarrassed.

Torishy continued onwards, before stopping, seeing a pit of spikes. "This will be hard for the earth ponies, but the unicorn, alicorn and pegasus ponies can fly or teleport. You two ca-"She cut herself off in amazement as the orange pony named Applejack jumped across with ease. "That was amazing, but what about you, pink pony?" Pinkie Pie walked across the pit, as if she was walking on air.

Torishy flew across. "I was wrong, you are BOTH awesome!" They crossed into the next room. It was marked as 'Ruins center'.
