Kingdom Key

Sora was laying on a couch after he saw the pony talk.
"So, Your from a world of magical talking equines?" Riku asked Twilight.
"Yes, and it's in grave danger.. Heartless are tracking me because I am a Keyblade Master". Twilight responded to Riku, With much sadness
"You.. sound sad, It's because of your freind Rarity isn't it.." He said.
"Riku, How-How do you know about Rarity?".
"She's a Keyblade weilder." He said..
Twilight Paused for a moment, She was surprised that a Human knew a pony. Sora got up from his slumber.
"Ughh, Riku... I had the strangest dream that That filly talked to me.." Sora said, thinking he had awoken from a dream
"Umm. It wasn't a dream. I can talk.. My name is Twilight Sparkle" Twilight responded while reaching out her hoof.
"Well.. Uhh, Nice to meet you Twilight! My name's Sora!".
The conversation on why Rarity had become a Keyblade master, and Why she was in danger.
"You see, You had seen the same person me and Sora had seen before the island was eaten by darkness. He told us that Destiny Island's had been connected to the outside worlds, Exposing it to Darkness. Once the darkness enters a world, A man named Ansem, will enter the world, Look for a pawn, and Destroys the entire world, then moves onto the next.." Riku had explained to Twilight.
"The Key you hold in your hands is know as "The Spark". It is said that if the 6 Ledgendary Keyblades are put together. A blade of Ultimate power is created. The Ultima weapon, Able to destroy anything within a single slice of the earth beneath you.
Your Freind Rarity has the 2nd Key known as "The Giver", We have to free Rarity from the Darkness in order to get the power of her Key Blade.".
"Wait, Rarity wasn't consumed by the darkness. She has been Normal, that must mean Somepony else is corrupted." She said.

"Then it's time to go to Equestria" Sora said.

The four arrived in Equestria, The streets were full of ponies when Twilight Looked out her window.
"OK, I'm going to use a spell that will turn you into Stallions. Are you 3 ready?".
The three said in unison "READY!"
Twilight's horn began to spark, Then it started to glow and a field of magic surrounded the 3. They opened there eyes and noticed that they were shorten than before.
