I'm Glad I Was Able To Help
The darkened sky briefly lights up from a flash of lightning in the distance. Cloudsdale is in peril, almost completely overwhelmed by monsters that had been unleashed from Discord's influence. All the chaos and disharmony made most of the usually white clouds turn into furious thunderclouds, and even this high up, rain fell on top of other clouds along with the occasional lightning. In this condition, there's almost no pony sane enough to stay, most had ran far away. Almost.
One of the ponies who's still there is a grey pegasus called Derpy Hooves, wielding a spear on her back and a saddlebag, running as fast as her hooves can carry her through a large abandoned builing. The torrent of rain coming from where the roof should've been made it impossible for her to use her wings, added with her condition. She's on the verge of exhaustion, having just fought an Ursa Minor to get something very important to ponykind. Her ragged breath is even harder to let out because of the water falling on her.
The other pony with her is a green male batpony with cyan mane. Compared to Derpy, he's much more armed, sporting an iron vest and a sword more then half of his body long. However, he seems to be more injured then the pegasus, but he keeps soldiering, even though he's running with a limp on one of his forehoof. Several bruises and cuts are also visible across his body. Still, he's running faster then Derpy, slowly able to pull away from the pegasus, even though he didn't mean to do it. Realizing this, he skids to a halt, then approaches Derpy.
"Come on... Derpy." He said between his breath. "We need to move quicker, the monsters... are closing in."
The pegasus also stopped to see her companion, panting heavily. It looks like her hooves can buckle anytime. "Ah, sorry, that battle really took it out on me..."
As they were talking, a stomach growl came out from Derpy, making her blush a bit and giggle nervously. "If only I had brought something to eat..."
The batpony looks around himself. Apparently, he didn't bring any food either, the mare is supposed to be the one that brings their supplies while he clears the monsters in their way. However, when the Ursa Minor appeared, Derpy had to help him by using thunderclouds to attack. Flying back and forth like that in high speed while getting electrocuted several times by the lightning she created by accident would be taxing. He figures that the last time Derpy had eaten anything must've been longer then his last meal.
"We need to keep moving." He said as he walks to Derpy's side, planning to carry her. However, to his surprise, Derpy holds him at bay with a hoof, shaking her head.
"If you carry me, I'm just going to slow you down..." The pegasus reaches for her saddlebags, and pulls out a golden necklace with a red diamond shaped like a lightning bolt, the Element of Loyalty. She gives it to the batpony with a light throw, thankfully he caught it despite his surprise. "You need to get that shiny necklace to the princess! You go on ahead, I'll catch up!"
The element is the very reason both ponies risk their life and limb going to Cloudsdale. Princess Celestia and Princess Luna are hoping to gather all the elements that somehow had been scattered around Equestria to stop Discord, and restore Equestria's peace from all these monsters. If the element should be lost, Equestria falls along with it. The batpony looked at the shiny red gem, then back to Derpy. Should he really leave her behind to deliver this to the princess? It's a very important item that can save Equestria, but the pegasus might not survive on her own out here.
"Derpy..." The batpony looks up, and as the lightning flashes, the silhouette of the monsters flying in the distance can be seen approaching. They had been there, they know what they're capable of, and in this condition, they can't take on that many. Not even he, who takes on the Ursa Minor most of the time and win, thinks he would be able to survive that many monsters. If they don't get going soon, the horde might be able to catch up with them.
"Don't worry, I can take care of myself!" Derpy smiles, her exhaustion seemingly vanished for that brief moment. Another flash of lightning in the background accompanies that sentence in a dramatic fashion. Her companion grits his teeth, knowing that every second will determine Equestria's fate. It's either the element returning to the princess, or both of them are going to die here and doom Equestria. Mustering all his strength, the batpony walks back, away from Derpy, slowly walking faster.
"I'm sorry, Derpy..." He grabbed the necklace tight with his limp hoof on his chest, and turns around, not looking back. "I'm so sorry..."
"Good luck!" The pegasus called out to him before her companion started to run as fast as he can to leave Cloudsdale. Soon, he's out of sight once he goes down a brick slope, leaving the mare alone... Not exactly alone with the monsters right behind her, though.
Derpy turns around and looks at the approaching monster, grabbing her spear. If she can fight them, she'll buy more time for her partner. She's in no condition to outrun or hide from the multiple monsters coming for her. No matter how little, even if she can make the monster stop for half a second... she did her part to buy time. Her stomach growls again, as if warning her about her hunger and exhaustion, but she doesn't care, this is the only thing she can do to help save Equestria now.
The first monster that comes in sight are harpies, two of them. With their claws out, the swoop in for the mare. Derpy managed to use her spear to stop the sharp claws from hitting her body, but it still managed to graze her coat. Pinned down, the pegasus desperately tries to push the pair of monsters off her, before remembering that in the rain, harpies would need to gain considerable momentum to get airborne, thus greatly limiting their maneuverability once they're on the ground. With a burst of strength, Derpy flips herself to the side, bringing both of the harpies down. Grabbing her spear as quickly as she can, Derpy grabs her spear in a firm grip, and thrusts it into one of the harpy's chest while throwing herself on it, drawing blood and killing it.
Before she can get up, the other harpy jumps on Derpy's back and drives it's claws, making the mare scream. The monster managed to get some scratch marks before Derpy managed to turn around, hitting it with her spear's rear. Once again laying on the ground, Derpy watches as the harpy, recovering from her strike, jumps on her, talons out...
STAB!
"Aglk..."
Derpy coughed out blood, the claw penetrated her coat, barely missing the base of her neck, the wound is quick to spill her life essence. Then, drips of blood fall on her chest as she looks at the harpy's abdomen, pierced through by her spear. The creature slumped, completely stopped moving after her attack. After tossing the dead monster aside, Derpy rolls and attempted to stand up. The place where she was laying down is now tinted red, her back must be bleeding from the previous attack. Each time she took a breath, she wheezes, and there's a painful and sickening feeling just below her neck where a claw was driven. The pegasus had to support herself with her weapon, unable to stand up straight.
FLASH!
Her vision suddenly went white as an unknown force made her fall, and a jolt of pain shoots her from her left side. She looked at it, and sees an arrow had completely went through her wing and lodged into her body. She looks up to see the culprit, a white humanoid creature that's missing it's lower body, Amalaric Snipers. These monsters wield bows and it's wings are unaffected by the rain. Seeing this horror, Derpy looked behind her, the fight had put her close to the slope that was just ahead of her before. She might jump towards it and maybe escape this monster, but...
Her breath feels heavy, her body is receiving pain all over, and she keeps tasting blood in her mouth, but somehow, the pegasus managed to stand up with a look of determination in her face. As the sniper readies another arrow, Derpy tightens her grip on her spear. All her life, the day she remembered when she's living happily with her parents, her first birthday party, her first muffin she tasted, flashed in her eyes. Now it seems that she will never get the chance to feel those again.
The arrow is fired, and it feels like everything went ten times slower as Derpy sees it coming towards her. Taking a last deep breath, able to feel and hear every beat of her heart, Derpy mentally prepares herself. She's ready for this...
At the very last second, she throws herself to the side, making the arrow clip her tail instead. With the last of her strength, the pegasus throws her spear towards the flying monster, hitting it right in the chest. It let out a horrible screech as it's body engulfed in flames, before turning into ashes.
As the rain washes her blood from her coat, only to soon be replaced by more, Derpy looked at the fallen monster's remains. She did it... she killed another monster to buy--
FLASH!
Mid breath, Derpy felt another arrow hit her right between her chest. The air got caught in her neck as her hooves reaches out in front of her from inertia as her body fell back towards the slope. She can't even scream, the pain is surreal, the last thing she sees before she fall down the slope is the flash of lightning, revealing at least a dozen snipers in the air. It felt like forever, but the first fall happened, followed by many more as Derpy tumbled down the slope, staining it with her blood.
Thud
Thud
Thud
Thud
Thud
Thud
As fate can be cruel, Derpy is still alive, barely, at the end of her fall. She cannot move any of her limbs, probably because it's broken, and her head is almost on the edge, giving her a view of the lands below. Her throat would sometimes gag involuntarily, making blood come out from her mouth. The slightest of breath are painful to take, her lungs felt like it's being cut open. The arrow in her chest, half broken from the fall is covered in her blood all the way. Each of the raindrop felt like pebbles falling on her. She never knew it was possible for a living being to get this much pain.
The pegasus knows that this is it. As she slumps her head and look at the lands below her, her eyes are fading to black, just like the clouds in the sky...
Then, a lightning strike.
It illuminated the area below as well, and she can see a figure of a batpony gliding down, a glint of light is reflected near it's chest. Seeing this, Derpy smiled. He had made it.
She have no regrets. From the moment she joined to serve Princess Celestia, she knows that everything she does, no matter how little, will be for the good of other ponies. She barely got any action unlike most ponies that Celestia choose to fight and protect ponies from monsters. Instead, she's usually sent to deliver messages or supplies, or like now, act as a guide around Cloudsdale. It's not as significant, but it's still something, and that's what it matters.
"I'm... glad... I was able... to... help..."
Those are her last words. As another lightning strikes the sky, the pegasus known as Derpy Hooves... is dead.

I hope those that play Ponyvania managed to save Derpy, because I saw what happened if you don't, and it was heartbreaking 
I'm Glad I Was Able To Help
An Unspecified Amount of Years Later...
The sun is shining, the birds are chirping, and the colorful flowers are blooming. Once again, Equestria had been restored to it's original state, peaceful and in harmony. However, the reign of Discord and the time of chaos had not disappeared without a trace, and the cemetery just outside Ponyville is a grim reminder to those who had fallen. Hundreds were buried here, but in front of one of the graves, a certain light purple unicorn is standing.
Here lies Derpy Hooves
Fought bravely for the sake of Equestria
24 BH - 3 BH
Rest in Peace
Those are engraved in the grave stone, surrounded by flowers. The female unicorn puts down a muffin on the grave gently, right before a cloaked figure walks behind her.
"You're early." The figure called, making the unicorn turn towards it.
"I don't have much time to spare, so might as well do it now." She replied. Her horn lights up and her magic engulfs the muffin. Cyan magic swirls on her horn, then a flash. The muffin turns transparent, making both of them smile.
"Always works." The unicorn smirks a bit, seemingly proud of what she had done. The figure chuckled.
"Time magic... and now ethereal magic. Tell me how did you became a guidance counselor instead of the Princess' personal guard again?"
"Because I choose to." She turns around. "Now excuse me, I need to get back. Perhaps some students need to see me."
With a flash of magic, the unicorn disappeared. The figure then opens it's hoodie with it's hoof, revealing a green, cyan maned batpony, the same one that had retrieved the Element of Loyalty from Cloudsdale. Since his kind seems to age slower then most ponies, he didn't look that much older. With a grim look, he reaches inside his cloak, and takes out a pair of glasses. As soon as he wears it, a spectral figure of a pony appears. She looks pretty much the same, except being transparent, and would be invisible to the naked eye. The special glasses allows the batpony to see the pony that had deceased long ago, Derpy Hooves.
"Derpy..." His expression looks sad, but the batpony managed to smile nonetheless. Derpy is looking at the muffin with a happy grin.
"Muffin! Is this for me?" To this, the batpony nodded, and Derpy immediately grabs the muffin and takes a bite out of it. Thanks to the spell of the unicorn, the food can be interacted by spirits, and thus Derpy can eat it. The happiness on her face is so heartwarming as she quickly chew the entire muffin into her mouth in no time.
"...I asked Princess Celestia if there is a way to please you... and she mentioned that you loved muffins." The stallion sat down, sighing. "If only I brought one during that day..."
Finishing her snack, Derpy moves closer to who used to be her companion. She places her hoof on his shoulder, only for it to went through, giving him shivers. The pegasus pulls back her limb with a nervous smile. "E-Excuse me... But, don't be sad. You saved Equestria, didn't you?"
Yes, yes he did. He's one of the ponies that stormed Discord's realm and fought the god of chaos himself. Resealing him brought the peace that ponykind had sought for. He heard that Discord is back out now, though many claimed that he's no longer seeking to throw Equestria into chaos. Though just in case, the batpony is almost always fully armed, he can't really trust Discord...
"I... We did, but I can't save you." His reply is to be expected, and Derpy is quick to answer.
"It doesn't matter, what matters is you saved many more ponies then me." She said in a cheerful tone. "I'm not sad or upset, I'm happy because I helped to make a difference!"
That sentence made the batpony sniff. What a wonderful pony Derpy is. If only she's still alive to live in a world she had helped to create... If only more ponies get to know her...
"Derpy..." The stallion wipes his eyes, smiling. "You're... amazing. I'm sorry that I can't give you what you need that day... but will you be happy if I give you more muffin next time?"
"Oooh! I would love to! They're delicious!" The pegasus jumps up and down, flapping her wings in excitement. Even though she's no longer in this world, she did not change one bit.
"I promise to give more next time, and maybe we can talk a bit longer too." The batpony stands up with a smile, ready to leave. He reaches out his hoof to touch the spirit of the pegasus. The contact sends a chilly shiver through him, but he doesn't care. "See you next time, Derpy. Have a deserved rest."
"Okay, good luck! And live a happy life!" The pegasus waves her hoof happily. Smiling, the stallion takes off the glasses, and Derpy vanished from sight. He knows that she'll always be there, though. The sacrifice that she did allows her to stay alive and save Equestria with the help of others. The only thing he can do in return is to give Derpy her favorite treat. Before he left the cemetery, he looked back at it.
"...No matter how small..."
All he did is take a muffin, and ask a favor from a powerful unicorn he made acquaintances from the time of chaos to give it to Derpy. He can't bring her back without resorting to drastic measures, and he's not sure if Derpy want that, but this small act of giving her a muffin is enough to make her happy, and that's all it matters.
"I'm glad I was able to help."
