Celestia, the raiser of the sun, sat in the entryway of the dungeons. They were currently empty, as always. But today was a bad day. Today was the day Twilight would meet her pet monster. Long had it been said that there were no monsters in Canterlot. That Celestia wouldn't tolerate a creature of death and fear in her capital. That was a lie. She kept the monsters hidden. Luna fought them off now, but Celestia never had the killing intent of her sister, or the vicious ruthlessness of Lord Emerald. That was in addition to being unable to kill this monster, even if she had those traits. Faust know's Luna tried, and all the creature did was laugh. So Celestia sat, awaiting her former student.

It was not a long wait. Twilight Sparkle came running within the hour, turning the corner with the sound of skidding hooves. Celestia wanted to smile as the youngest princess ran up beside her, but found herself unable. Life for both princesses was about to get much more difficult, though hopefully no more dangerous. "Twilight, I have some bad news today."

Twilight let out a pant, and her face seized in panic. "What's the matter, princess? Is there another threat to Equestria? Is Sombra back? Did Discord relapse into villainhood again? Did Tirek escape again?"

Celestia shook her head as Twilight began a delve into madness. She was disappointed that it seemed like a short journey for her student to descend into blind fear, but such was life. "No this a much more serious issue. It is also an older, and quieter issue. Before I even begin talking about it you must swear to never let the events of today go outside these walls. No notes, no hints, and never telling somepony who isn't a princess. Your friends cannot know about this." Twilight nodded and flinched back as Celestia lunged closer. "SAY IT!"

"I swear to never talk about this." Celestia retreated a step but kept up her glare. "and no notes."

Celestia nodded and began walking away, with Twilight caught in her wake. "What I am about to show you Twilight is the most dangerous being in Equestria. It is also the smartest. It is an undying force, unable to be slain by any methods. Even imprisoning it in Tartarus doesn't work. It simply leaves."

Twilight ground to a halt. "It just leaves? It simply walks out of a pocket dimension that rips the soul out of anything trying to leave unless they can orchestrate a self-summoning to happen, at the minimum, fifteen-hundred years after their imprisonment?"

Celestia nodded. "Indeed. It will walk out and disintegrate into a cloud of fine dust, then reawaken a few days later outside. It is unable to be contained by most mundane means. In fact, I think the only reason we still have it contained is that it finds us amusing."

Twilight started moving again, breaking into a quick trot to catch up. "It allows itself to be locked up because it thinks we're funny?"

Celestia shook her head. "No, it finds our efforts to contain it funny. It also craves social interaction. A pony must talk to it once a week, or it will leave. But if that was it we would probably let it be. It is mostly peaceful." Twilight looked shocked. She couldn't fathom a reason that the princess would imprison a mostly peaceful creature. Celestia let the pause hang for a moment before speaking. "It is imprisoned because of its knowledge."

Twilight blew a mental fuse. It was unthinkable. Something that knew so much that the princesses had to imprison it? How much could it know? How much could it do? She tried to put this all into words, but they faded into one simple question. "Why?" She barely got it out.

Celestia sighed as she reached the first checkpoint, waving away the wards with a wing. "Did you know I thought the elements permanently banished Luna? Or that Discord would return within a few years after sealing him? This creature can predict the future with alarming clarity. It seems to be able to tease the future from a simple summation of any event." Celestia paused. "As long as the event is large. It appears to have trouble with simpler events."

Twilight had been hit with so many revelations this one seemed to barely phase her. Celestia knew in the days to come she would have to rationalize it all. But there was no time for that now. It was sink or swim for the young princess. The second and final checkpoint loomed in front of them. Celestia dismissed the wards. "And now you must continue alone my friend. It will not speak to you if any others follow. Be careful, and whatever you do, remember one thing. It does not lie, and you must keep your word."

With that, Celestia left the confused young princess. The door open and waiting. She took a moment to take a few breathes, before walking through the doors. She found herself in a small room. A simple bed lay in the corner, with a table in the center. A bookshelf was beside the bed, and it was filled with various foal books. Half were opened and scribbled in. Twilights inner librarian let out a twitch as she saw them until she noticed the scribbling were in a different language. One she had never seen. Then she noticed the creature. It sat in a chair beside the table, wearing a skintight outfit. A small web of fabric holding various tools in pouches over her chest. It only had hair at the crest of its head, which was a long red curtain that trailed down her back all the way to its hips. It was also staring at her.

They sat in silence for a moment, before the creature shrugged and cut a slice off of an apple and popped it into its mouth. It then pointed the knife at her, causing her to jump back. "Stories. Seen a lot of them." It said, in a smooth feminine voice. "And I've seen you before. Twilight Sparkle. The former student of Celestia, got caught up in some time travel mumbo-jumbo. Became a goddess. Not in that order of course, but I'm proud to say I knew you would ascend the second Celestia took you in." Twilight stared as the creature slowly stood up and looked her over. "Yes, she was much to wild. No control. You, however, had control, at least most of the time. That whole doll thing showed you can crack if a self-professed rule might be broken. I can respect that. It's stupid, but I can respect it." It began to slowly circle her. "Hm, I'll be honest. The story in my head had you swarming me with questions. Fear was my third choice. But little things like a base reaction are much easier to mess up without direct contact. If I actually wasted the time to watch you I might have gotten closer."

She finally stopped moving and walked back to her chair. Twilight found her voice a few seconds later. "What are you?"

The creature let out a chuckle. "Oh, Celestia doesn't know my name. Nopony does. None of them wanted to ask. But I'll tell you. For a cheap price too. One question and one spell. You have right of refusal on the spell of course, so if you think it's to sketch then you can tell me to frack off."

Twilight got excited at the simple thought of knowledge nopony had ever gotten. Why would nopony ask her name? It was also apparently a cheap price. Despite its odd vocabulary, she couldn't refuse the offer. She nodded. "Of course."

The woman nodded. "If you don't mind I'd like my part first. I don't want to be burned on a deal again. Literally." Twilight pushed that sentence to the back of her head and nodded. The creature smiled. "Curious and naive. A beautiful combo. For my question. Can you sense friendships?"

Twilight thought on that. She had seen it before. A string of thin blue lines, seemingly in every direction from a pony that she focused on. She nodded. "Yes, I can." And she knew the creatures next question as well. It wanted to know if it had any friends. And she smiled. It didn't lie, so it couldn't get an answer without another deal. And she was ever so curious.

When the creature spoke Twilight smiled wide. "Cast whatever spell that will let you see my friends. None of the other princesses could tell me what I want."

Twilight did so and faltered. Two lines came from the creature. The thickness of the lines denoted how strong the friendship was. The greatest friendship she had ever seen was about the thickness of her hoof. And it was between her friends, who had banded together to fight everything that Equestria could send. But these two bands were as thick as her barrel. And she heard the most disturbing thing that ever ran through her ears. She heard the creature let out a soft chuckle.

The creature was calmly leaned back, propping her feet up on the table. "Thank you. By your reaction alone they're still alive. Or at least one. And as the ancients said, a promise made, a promise kept. Demoin."

Twilight paused. She did have the creatures name now. And she had info that Demoin wanted. She just had to push her advantage. Against a dangerous creature that was only contained because it wanted to be. That should be easy. She let out another breath. "I'll tell you how many." Demoin let out a half-smile. "If you tell me how you got here."

Demoin's smile dropped. Followed by her as her chair went backward. She hit the floor, and the knife cleanly went through her hand. She glared at it as if annoyed before ripping it out. Blood splattered over the table, and Twilight could see the white shine of bone under the blood. Twilight watched in horror as Demoin calmly wiped off the knife and put it back on the table. "That was unexpected. You were supposed to ask about my friends. I was almost sure of it honestly. Ah well, this just makes you interesting. But for that, I want to know if they're moving or not. That is if you can tell."

Twilight smiled wide. "I believe I can. Just tell me your story first."

Demoin chewed on that for a moment before nodding. "Very well. I was on a ship, traveling through a realm you've never heard of and I don't know enough to explain. Me and my friends crashed. I secured them before I was jettisoned from the ship a few miles above the ground. I died, got back up, and was captured by several interested parties. Now I'm stuck here. At least until rescue comes."

Twilight was nearly giddy. She had let slip she was securely contained here, and that they had an entirely new method of travel. Even if the creature couldn't explain it future deals might give her enough insight to explore the idea herself. But she had a promise to keep. She focused on Demoin, staring at the lines. One twitched upwards a few times, before settling again. The other slowly moved to the left. She stopped there. "Yes, they'removing. There are two, and they're either moving slowly, or they are far away."

Demoin sat the chair back up and sat down. She stared at her hand before Twilight was struck with a metaphysical force. She had the sudden feeling of a rock looking at a mountain. Like she was seeing something that had been alive far longer than any sane being should be. That even with her immortality, she would last for an eyeblink compared to the thing in front of her. And she saw the wound close. No magic, no spells. Just the wound rushing over itself, and the hand being fully closed.

Twilight was dumbstruck as the feeling passed. The feeling had passed, but the shock was still there. Something was wrong with this creature. This thing was an immovable object against the rushing water of time. Demoin looked at her with a sheepish smile. "Sorry, forgot you demi-mortals aren't used to that kind of thing. Anyways I'll give you a small tidbit for free. My friends will be coming for me. If they ask, just hand me over. If you don't, then your kingdom will fall. Your cities will burn, and your people will die." Demoin delivered this without a trace of emotion, barely seeming to care. "But if you do release me, we'll be peaceful. Might even try to trade sometimes. Either way, If they're up and about I'll be out of your hair soon. Now get on out. I have to check over the entire world and a dragon ate half my nodes. Being stuck here really lowers my ability to scry."

And with that curt dismissal Twilight left, unsure of who used who more in their encounter. But she was sure of one thing. This wasn't going to be their last talk. With the room now vacant except for Demoin, the immortal moved to her bed. From underneath it, she pulled a small glass pane. With a swipe of her hand, the glass exploded into colors. Videos and pictures dancing across the screen. Her hand paused on one, expanding the picture to fill her entire view. Eight figures smiling in front of a ship. She could see herself, crouched in the back. She had been hesitant to take a picture, and only joined at their insistence. But the other seven... Five were dead now. She tapped each one, thinking of them fondly. Her thoughts finalized on the two that were left, and she swiftly moved photos. The nest one was older, with five figures in it. Crouched behind cover as flames scorched around them. A skeletal figure wearing a simple robe, lightning arching from his fingers as ethereal dragon wings sprouted from behind him. A goblin, his hair on end as he tinkered with a broken explosive, lightning arcing between his fingers. A Githzerai, the minute green creature screaming in joy as silver tattoos were captured with fur growing out of them, his normally small teeth expanding as massive canines erupted from his mouth. An Aasimer, heavy armor covering his body as he simply sat low, two large fangs glistening as he smiled. And finally an elf, her hair long and flowing, with her chest cavity open as a massive orb of light shone from it, mechanical servos mid-spin showing through her skin.

With a soft sound, Demoin collapsed onto her bed. Nothing was there with her, and all alone she wept for the dead.
