"This is a picture of her" said Mystic, handing Tempest a picture of the long lost Princess.

"Well, sorry, you've gotten in contact with my sister, Princess Twilight instead" explained Tempest, watching Mystic's face fall.

"That can't be! I checked and re-checked. It has to be her!" cried Mystic.

"Wait, you said something about old enemies rising in you're letter. What did you mean?" Tempest asked.

"The Razor Lord. He has returned to Equestria. I saw him a week ago. He is like a large yeti, white fur, two large upward teeth, claws, two long black horns, ugly darkish face, growling expression" explained Mystic.

Tempest looked at her shocked. "That description sounds like the Storm King. He became stone and was smashed. I used to be on his side"

"Oh, I remember you. You caught Twilight and her friends. The Storm King would have gotten Princess Tranquil's magic, but he wanted the four princesses' magic first, and then make her watch this world suffer. Princess Tranquil was very close to her subjects, closer than Princess Celestia. He wanted to torture her mentally, because she was the one who banished him in the first place, back when he was the 'Razor Lord'" explained Mystic.

"Wow. You sure know a lot about this all" marvelled Tempest.

"Yeah. But now, he's back, and we need to bring Princess Tranquil back. Only with the power of all the princesses can he be defeated" said Mystic.

"How to we get Princess Tranquil here?" asked Tempest.

"There is only one way- sacrifice" said Mystic solemnly. Tempest gulped.

"Kidding! You should have seen your face!" laughed Mystic, "Seriously, we have to cast a spell by all the Princesses"

"Well, let's get going. I'll tell Twilight" said Tempest, running outside.

"Fifth princess? I mean, sixth princess?" said Twilight, remembering Flurry Heart.

"Yup, Twilight, meet Mystic, Mystic, this is my sister Princess Twilight" intorduced Tempest.

"Mystic? Didn't you disappear from Equestria? Your family thinks you're dead!" said Twilight.

"Nope. I'm here. Sorry everypony was worried, but I had to find out about Princess Tranquil" said Mystic, feeling guilty.

"We should go to the princesses. There's a summit tomorrow, we should meet up there" said Twilight.

That night, they got ready to meet the princesses, and ask them about the sixth, well being Celestia and Luna's younger sister, third. That made Twilight number five, which was pretty confusing.

When they met up, Tempest just asked them without ado, forgetting Twilight's plan of 'subtlety'.

"Princesses, can you tell us about your sister?" asked Tempest.

Luna and Celestia gulped, "What sister, we have each other!"

Mystic stared at them incredulously, "Your highness, we're talking about Princess Tranquil!"

At her mention, Luna burst into tears. "I tried to stop her. She didn't listen" sobbed Luna, and Celestia comforted her.

"It's hard without our beloved sister, and not being able to hold rememberences for her. And no one can understand" said Celestia, silent tears streaming.

"I've figured out how to bring her back your highness. Spell of Environmental Reconciliation, which was Tranquil's talent" said Mystci handing her a scroll

Celestia's eyes scanned the scroll and her smile returned. "This is wonderful. Candence, can you bring Flurry Heart here?"

Cadence brought Flurry Heart, who was playing with her Whammy. "How can Flurry cast the spell?" said Cadence, as Flurry sneezed, creating a hole in the roof.

"I have a spell which will make her sneeze the spell she wants. If you hand her the scroll, and she sneezes, she will sneeze out that spell" said Celestia, lighting up her horn and touching it against Flurry's.

"Everypony ready?" asked Luna, wiping her tears.

"Ready" replied the others, as Tempest and Mystic stepped back. Celestia shot out a yellow laser, creating a yellow orb, Luna added her blue to it, Cadence added her pink laser and Twilight blue. Finally, Flurry sneezed, shooting out a aqua laser this time.

The orb expanded and glowed, as the alicorns struggled to keep the spell going. It became larger and larger, and it exploded, a small rainbow. "Well that went well" said Twilight sarcastically.

"We needed all the princesses, it should have worked" cried Mystic. Everyone looked at Celestia and Luna.

"Trust me, there are no more princesses. Honestly, I did the Princess of Love, Friendship, what else? I know I'm supposed to know everything, but I don't know why it didn't work!" ranted Celestia, while everyone stared.

"I think I know what happened!" said Tempest, "We needed all the princesses for the spell to work. So maybe Princess Tranquil also has to cast it, being a princess!"

"Oh my gosh, you're right! We need to get a message to her" said Mystic. Everyone looked at Celestia again.

"Oh for Celestia's sake!" cried Celestia, "Oh, sorry, I've gotten used to people using me as a saying, I used my own"

"In all seriousness, both of us do not know how to get a message to Princess Tranquil" said Luna.

"I think I've cracked that as well" declared Tempest, "If she's in Tartarus, and no one can reach her, why don't we ask for help? Someone powerful? Someone who used to rule this world?"

"Discord" groaned Twilight, slamming her hoof onto her face. Discord appeared on cue.

"Well this just isn't fair. You all ignore me, and call me when you feel it convenient!" said Discord.

"Please Discord, only you can get a message to her!" pleaded Tempest.

"This seems like one of those days you're desperate. Okay, if you let me have one day of pure chaos, I'll do it" said Discord.

Everyone looked at Celestia for approval. She rolled her eyes, "Fine!"

"All right! Write on this scroll and I'll send it" Discord instructed.

The Royal Sister took a deep breath, and began to write,

Dear Sister

It has been too, we have missed you everyday. Why did you have to go? A smart young mare, Mystic, has figured out how to get you free. The Storm King, aka. Razor Lord is free, and we need you. Use this spell, because we need all the Princesses to use the spell, then and only can you be free. We wish to see you as soon as possible.

Your loving sisters, Celestia and Luna

Hopefully the message would be successful, and Princess Tranquil could return.
