"Who could've done this?" Celestia said, reading the letter. It's been seven years since an evil has plagued her ponies, and now both the forest invade and the sun and moon are fighting against their magic, it was humiliating. The canidate; Naturus, a being who was killing off the ponies and even other sentient races at an alarming rate.

Ever since Naturus showed up in Canterlot, the sun and moon were starting to resist control, and due to the little fight she and her sister were slowly losing against, their magic has drained a ton, their manes were no longer ever-flowing, but retracted to the normal texture of hair, but that doesn't mean that she and Luna were still very powerful. The only one unaffected was Discord, but even he couldn't counter Naturus.

"Sister, what's wrong?" Celestia turned around to see a light-blue alicorn with a lighter blue mane. "Ever since we've been notified by refugees who've fled their home countries to avoid being killed by Naturus and his army, our magic has dropped at an alarming rate..."

"...who or whatever he is, he is more powerful than Tirek and Discord at their heights, and doubled by his immunity to magic and his knowledge about our strengths and weaknesses, well, talk about a hard foe to defeat." Luna said, nuzzling her sister before a flash of light came. The two sisters looked to see the Mane 6, Twilight ran up to them, crying as she did.

"The... the Tree..."

"It's..."

"It's..."

"What is it?" Luna said.

"It's... GONE!" Twilight said, sobbing.

"Naturus... he... I don't know who or what took it, but it may be connected to Naturus." Celestia said. They walked down the halls until they went halfway to the throne room, the sound of rain filling their ears. Ever since the Everfree started to invade again, weather everywhere has gone haywire. The went to a door on the left. Twilight cleared her throat and said "He... also captured Spike, if we can find him, maybe we can find the Tree of Harmony as well..."

Before Twilight could finish her sentence, cracks began to form on the wall, until...

BAM!

When the smoke cleared, the saw a giant bird-like creature, bigger than an elephant. It had brown feathers on its body, save for the creature's muzzle, legs, and tail, which were covered in dark grey scales. Its beady black eyes stared at them, its mouth drooling with hunger.

"GWARK!!!!" It squawked, almost biting one of them. "Ugh, that's very bad breath!" Fluttershy said in disgust. What they didn't know was that creature, belonged to the famous T. Rex species, and boy, it looked like it wanted to eat them. "RUN!"

They ran out of the room, the T. Rex following them, bashing through walls, hoping to eat them. "What is that thing!?" a nearby guard said before the T. Rex bit the poor guard and swallowed him whole. "Oh no, that poor guard!" Rarity said as she looked back. "This is worse than the Yeti we ran into!" Pinkie Pie said. "Yeah, I agree!" Rainbow Dash said. Twilight procceded to shot a laser at the T. Rex, but it failed as it opened its great mouth and chomped on it, smoke coming out of its nostrils.

"Oh no, that didn't work!" Twilight said as the T.Rex advanced. "He's gaining on us!" Luna said. They galloped down the halls and into the city itself. By now, the rain has became a thunderstorm. While running from the T. Rex, who was busy chasing other ponies, they took note of several species of animal running around, but had no time to admire it, for another T. Rex was chasing them.

"GWARK!!!"

"The city doors! They'll be unable to get out!" Twilight said. "GO! HURRY! IT'S NOT SAFE!"

They went to the city doors and locked it, making sure enough ponies can go out. They were about to leave when a giant cat with saber-like teeth roaring at them, well, a whole pack. "Oh, no!" Twilight said. They looked behind them to see the doors break, revealing the same T. Rex from the city, saliva and blood drooling from its mouth. "We're trapped!" Celestia said. "Wait, can't we teleport?" Twilight said.

"...because there's a METEOR HEADING STRAIGHT FOR US!!!" a pony said. Twilight, Celestia, Luna and Rarity gathered their magic and teleported Canterlot's residents, just in time for the meteor to strike, killing one of the Rexes and forcing many creatures to flee.

--stop music--

Any pony with a good veiw of Canterlot watched in horror as the meteor smashed the once great city into bits, or at least, anybody who loves the city, anyways. Over three hundred casualties were caught, it was a sad day.

"Twilight, we're okay." Celestia said.

"I know, but what caused Naturus to attack us?" Twilight said.

", I don't know..." Celestia said, looking out as the sun rose by itself.

"Well, you should know!" Naturus said, his all-seeing eye fixated on the ponies. He then turned his attention to the finished thought. "Hopefully, I will make SURE that the new sentient races will know better!"
