Twilight groaned. Everything was black, and she had no idea where she was. She cracked open an eye, and found she was in the library, where she had been before...
It all came rushing back to her. The teleportation, the fight, and... Rainbow Dash... That monster that called itself "Dimentio" had killed Rainbow...
Twilight started crying. Why? Why had Dimentio attacked them and killed Rainbow? Why was this happening? As she was crying, a tear fell onto Rainbow Dash's body, and started to glow, create artistic patterns, and basically do magicky things in typical Disney or anime fashion. Rainbow moaned, and her eyes fluttered open. "Twi...light..."
Twilight froze, and looked down at Rainbow Dash's body. "Rainbow? RAINBOW!" Twilight threw herself upon Rainbow Dash with gusto, hugging her tightly.
"Hey, Twi, get offa me! It's good to see you too, but there's personal space!" Rainbow managed to croak out from under the tight hug.
"Sorry..." Twilight muttered, letting go. "But how are you alive? That magic looked fatal..."
Rainbow squinted her eyes, thinking. "There was a... line? Of things that looked a bit like Dimentio, but all black and grey... But then a demon in a suit saw me and told me that I didn't belong there. He grabbed me with a... skeleton thing... on the head, and then I woke up here."
Twilight sat up, thinking. Dimentio's magic could have sent her to the Underworld of his dimention... That's fascinating. Based on the thing delivering the death's afterlife, the dead one goes to that afterlife? Strange, but intriguing.
Rainbow stood up on her hooves. "We should tell our friends about Dimentio! If they see him, they'll know to be careful, and tell us! Then maybe we can use the Elements of Harmony on him!"
Twilight grinned. "Good thinking, Rainbow! Let's go!"
The Elements of Magic and Loyalty ran up the stairs, and out of the library. But as they scrambled to get the information about Dimentio out, trouble was brewing in the Everfree Forest...

The Everfree Forest, Castle of the Royal Pony Sisters...
In the tallest tower of the Castle, where Nightmare Moon was purged from Princess Luna, and the Elements of Harmony were found, reality seemed to flip in a rectangle, bringing a figure out from the other side. This figure was, of course, Dimentio. "Hmmm..." he mused. "My teleportation took me to the highest level of dark energy near those stupid ponies, so I can give them a real show, but where is all the dark energy?"
The dark energy seemed to be coming from everywhere and nowhere at once. This was the weakened power of Nightmare Moon, its sentience gone and its power dissipated into the stones of the tower.
Dimentio snapped his fingers, and a detector that looked suspiciously like a Nintendo DS flipped into existence. "Had to loan this from Fawful... Well, he doesn't need it anymore, so I don't have to return it."
The detector's satellite dish spun everywhere, detecting dark energy all around it, but it decided on a certain spot near the raised podium at the far end, away from the stairs. This was the spot where Nightmare Moon had been standing when she had been purged.
Dimentio floated over to the spot, and cast a spell to determine what kind of dark energy it was. The results came back- the energy wasn't chaos energy, but simply magic corrupted by jealousy and hate, which made it useless to absorb into himself to boost his power, since it would not do much and cloud his judgement.
Just then, Dimentio's mask started to glow. It flew off his head, and hovered over the spot he had just been analyzing. Its light turned black, and in an explosion of pure darkness, the mask duplicated itself, the original floating back to Dimentio, and the duplicate laying on the ground. Quickly, Dimentio cast a magic detection spell on both masks, since they might have gained magical properties due to exposure to the dark magic. His mask had only its usual expression enchantment, but the duplicate had properties similar to that of the Floro Sprouts he had once used to gain control over the bulky, stupid O'Chunks and the green one with the shag upon his lip. Dimentio smiled. This had possibilities...

Sweet Apple Acres...
Twilight and Rainbow Dash came galloping through the gate of Sweet Apple Acres. "Applejack!" they cried, looking for their friend. Applejack came out from a row of trees, having been bucking apples.
"Hey Twi, hey Rainbow, what brings ya both here today? Yah seem awful tired..."
"Applejack, there's a monster around! It says its name is Dimentio, and it attacked Rainbow and I! It's awful, and we have to stop it!"
Applejack pulled her hat down lower on her head. "Well then, let's go stop it. Ah'm not gonna just stand here while a monster is goin' round town, attackin' ponies! It ain't right."
Twilight smiled. "Great! Let's go get Fluttershy, Rarity, and Pinkie! I'll ask Spike to send a letter to the princess when we get back."
As they all turned to leave, a familiar voice rang out. "And so I appear, like a sudden firework at a festival celebrating the greatness of Dimentio..."
Twilight growled. "YOU..."
Dimentio grinned. "Ah, yes, Ms. Fiery Temper. It is, in fact, me. Are you surprised?"
Rainbow leered. "I oughta teach you a lesson! Come on, put 'em up!"
Dimentio laughed. "Ah ha ha... The one you should be giving the lesson to is yourself! The lesson of intelligence, for you have less in your tiny little brain than a chipmunk!"
Applejack scowled. "Why, you..."
Dimentio continued. "Or perhaps you should be giving a lesson to my friend here, hmm?"
The three friends looked confused. "What friend? You don't have any friends, obviously!" Twilight yelled.
Dimentio's grin was as wide as the torso of Queen Bean (from Superstar Saga, look it up). "Why, this friend, of course!" Reality spun in a rectangle, bringing a manticore into existence next to him. But something was wrong. The manticore had a mask on that looked exactly like Dimentio's.
"Like my little experiment? I was wondering if this would work, and it did! So now my little experiment will experiment on you! The experiment of... dissection! Sorry, but I can't hang around to watch. I have more masks to make. Ah ha ha... Ciao!"
A rectangle appeared, swallowing Dimentio. The manticore started growling at the trio. "Uhh... nice kitty?" Rainbow gulped, recalling her earlier experience with manticores. The manticore simply roared from under the mask, and took a swipe at her with its claws.
"Hey, nomanticore touches my friends!" Applejack cried, batting its paw away. It growled at her, and the three friends got into a fighting stance, ready to fight the manticore...
