I was a moonless night in Equestria. By moonless I mean that the clouds obstructed the moonlight from touching the land.
Princess Luna had taken it upon herself to investigate an odd magical anomaly she sensed in the Everfree Forest. It was only her because her elder sister liked her sleep in the evening and the royal guards did not like venturing into the last remnant of Discords reign.
"Why doth a tree make it's limbs hang this low to the ground?" the dark blue furred princess removed another treebranch from her path to the anomaly.
"No wonder no pony hath ventured into this heinious forest ever since We liberated Equestria." she removed another tree branch out of the way. "The path is unwalkable and it smells of dead flora."
When princess Luna made the path free of a fallen tree that must have been lying there for quite some time, she encountered a sleeping manticore.
Slowly and carefully she spread her wings and sneaked past the unconcious beast.
However, it was in vain as she stepped on a stone that was hidden underneath the leaves and mud on the ground. The sound of her horse shoe against the rock was loud enough to wake the manticore from it's slumber.
"Dear Us." Luna silently cursed as the wild and large animal took notice of her and let out a loud roar while exposing it's bat-like wings and scorpion tail.
The beast swatted it's front claws at the princess and hit her with full force against a tree, making said tree fall down and rendering Luna barely concious.
The last thing she saw before she closed her eyes was a silver circle within a white circle within a black circle rolling in front of her face.
Moments earlier.
Prime drove his red and white roadster out of the blue portal. The portal vanishing behind him when he got out of the car.
"The fuck did I just do?" he lifted his eyebrows when he closed the door of his car.
Just as he closed said door a loud roar could be heard in the close vicinity.
Not taking a second thought, he jumped back into the car and drove towards the sound.
When he got closer after a few seconds, he saw a feral beast had just hurt another creature.
Prime stopped his vehicle near the hurt creature and pulled his Assault Rifle out and shot the wild animal in the face, killing it swiftly.
With the monster down in a puddle of it's own blood, Prime took a look at the other creature.
The creature had dark blue fur covering it's entire body. Wings on it's back had the exact same color in their feathers, just like the horn on it's head. It also wore a black and white dress that wouldn't look out of place in the Victorian era. The hair on the creature's head was blue translucent and glittered in a way that remided Prime of the night sky. Using his logic he guessed it was a female.
Having no way to get back to Los Santos and having no idea where he was, he decided to clean up the wounds on the blue woman and placing her neatly on her back.
Prime himself just decided to lean against the side of his car and keep watch. After all: if one of those beasts existed, more would surely follow.
The moment Luna woke up, she noticed something different: she didn't wake up in her bed. Instead, she woke up on the ground in the Everfree forest.
Another thing catched her eye: somepony was watching her while leaning against a red and white metal structure. Said watcher also seemed to smile as he saw her wake up.
When Luna looked around for a bit, she also saw a dead manticore covered in it's own blood with a messed up face.
"Hast thou slayed the manticore?" Luna asked the other pony. All he did was walk towards her and wave his arms around.
When he got close enough, however, Luna could see his face was anything but that of a pony. Instead his muzzle was replaced by a mouth underneath what she could only assume was his nose. His eyes were covered by heavily tinted lenses within a golden frame. His mane was swept back, exposing his forehead. His hands were covered in shiny black gloves and his hooves were misshapen and covered by his all black shoes.
His appearance alongside his arm movements resulted in a frightening sight for the princess, so she scrambled to get back on her hooves and hide from him.
When the princess found a hiding place behind a large fallen tree, she noticed the white bandaids covering some of her wounds. Feeling said bandaids, she noticed that they were made of the same material as the white parts of her dress. She also noticed that her dress was in horrible shape as pieces were ripped off, leaving nothing left to guess where her improvised bandaids came from.
Whe she looked up from inspecting her dress, the face of the strange stallion was right in front of her. This got a high pitched and short sqeak out of her muzzle.
"Was this thine doing?" she pointed at the blood soaked pieces of cloth over her now healed wounds.
The creature nodded.
"Then thou shalt be rewarded for thine effords to serve a princess of Equestria." Luna tried to look as regal as possible while covered in grime and sitting on the filthy forest ground.
"We must return to the castle for thee to claim thine reward." she stood up.
"And ,most importantly, for Us to make Ourselves more presentable." she added with a small blush that was visible even through her dark blue fur.
The creature also stood up and walked calmly to the red and white structure. It opened a latch on its apperant side and pointed towards the opening.
When Luna looked inside the contraption, she saw seats made of a red and smooth material and a few metal ornaments.
Taking the hint, she took position on one of the strangely comfortable seats.
Prime's perspective
This was the first time that a woman sat inside of his car that wasn't a prostitute or Rox. At least, he tought it wasn't a prostitute.
She said she was a princess and that she was going to reward him at her castle, wich, coming from the city of saints, could mean anything from a blowjob to a huge amount of money to falling in good graces with an important figure in town.
Either way it was a win-win for Prime.
