Demon Soul Pony Heart

(Five years later.)

"Come on Phantom it's time to get up, dad is going to teach us demon magic to day." Said a young filly with light orange fur and light pink mane. she had two small gazelle like horns that leaned on her fox ears her hoofs had small paw like nubs on them and she had light pink three fox like tails her cat like eye glowed a sinister purple as she was poking a navy blue colt with a black mane laying on a pile of bones. he had small axe like horns and dragon wings with small razors on their edge, small claws on his front hoofs and a serrated whip like tail.

"I'm up, I'm up calm down Ember your going to wake up mom." Said Phantom opening his cat like eyes which glowed red as he stretched out on his pile causing a skull to roll of the pile without ether of them noticing causing it to hit Ash who was resting next to the pile.

"Oh right let's go." Said Ember a little quieter.

"Phantom Blade, Ember Dagger where are you two going?" Asked Ash without moving.

"Were going to meet dad in the lower corridors." Said Phantom as he finished stretching.

"Oh yea your demon magic lesson is to day isn't it. Well I'm not going to stop you,  go and have fun, just stay away form the bad ponies that have been wondering around here and the silver gate."

"Ok momma." They both said before running to a near by staircase meeting enigma three floors down and next to him was ten tied up knocked out guards.

"Little ones before we start I've two presents for you both." Said Engima.

"PRESENTS!" Both foals said excitedly

"Yep that's right now as you know I am a demon lord and since your my progenies you both get two demon servants." Enigma raised his fore hoofs and slammed them creating two portals behind him and from those portals a black and a blue orb popped out black orb went to Phantom and the blue orb went to Ember circle both of them before transforming. The black orb turned into a changeling with giant red bat wings, long antenna and a white fur around It's neck and gray eyes. The Blue orb changed into a panther with a rows tendrils coming of its back. "Phantom Blade this is your guardian and servant, Loveless."

"Pleasure you meet yea, sugar I just know well have lots of fun together. Said the Changeling as she moved and laid next to him.

"And Ember Dagger your Guardian and servant, Life Bane."

"Hello lady Ember I swear to never leave your side." Said the panther as the tendrils  on his  back wrapped around him and turned into armor. Ember and Phantom were stunned speechless but their father continued

"Now you second gift which ties into to todays lesson." from the portals a necklace with a bottle hook on it and a tiny satchel  emerged  the satchel went to Phantom and the necklace went to Ember then Enigma closed the portals and brought three Guards over. Ember, Phantom shake off the surprise it's time to learn."

"Yes Papa." Said both half demons focusing on what Enigma was going to say.

"Those items I gave you two are very important they allow you to store souls."

"Souls?" Asked Phantom with new interest

"That's right. Today I'm going to teach you how to take the souls from others now close attention because its a little tricky." Enigma took one of the guards and stared at the pony. "First you focus on your target use your eyes to read them to read who they are and it means to be them." Enigma's eyes started to glow as his stare got deeper Then Phantom and Ember each moved to a guard and did the same thing as their father and just stared until they saw it a the ponies light up which in turn caused Phantom's eyes to glow red and Ember's eyes to glow purple. "Good now let your darkness reach out and condense the soul." Enigma's eyes changed they narrowed as waves of demonic energy invisible to anyone without demon blood flowed from him battering the guard causing the light Enigma saw to condense in to a small ball. This time it took the kids a longer but after a few minutes the waves started to come off them as well. "And finally just reach in and take the soul." Enigma reached out with his claw hoof and it sunk into the guards chest and after a second he pulled out with the soul in hoof leaving the empty guard to sit their but when kids tried it the guards screamed waking the other guards Phantom was holding his guard's heart and Ember was holding a lung.

"Darn we messed up." Said Phantom with a disappointed tone.

"Hahaha I didn't expect you to get it on the first try that's why we have multiple test subjects but that was a good try." Enigma said with a happy tone but then he heard a soft rumbling. "Did you two eat?"

"No daddy." Said Ember rubbing her stomach.

"Then dig in." Ember and Phantom both bit into the organs they were holding consuming them before starting on their test subjects. "Speaking of eating you can eat the souls you collect to make your demon sides stronger."

"Cool." Phantom said licking the blood of his mouth with little luck before going back to finish the dead guard below him.

(Ten years later.)

"Ok Dad set them up we're ready."  Said the older Phantom as he got in a crouching position his longer tail was waging slightly the razors on his wings extended a little bit as well his more forward pointing horns glowing a soft crimson along with his eyes.

"Are you sure? This will test everything you learned from me and your mother. Theirs no shame in holding off."

"Quit your babying dad, just shut up and set up." Said the older Ember who was sitting up next to her brother letting her huge tails shift around as she looked down her new forward pointing horns which like her longer back horns were glowing a soft purple just like her eyes.

"FINE THEN!" Enigma yelled as he stomped his foot the hallway divided Phantom charged down his hall jumping spikes that came from the walls flying when the floor disappeared and using his wings horns and tail to cut and slash thing in his way until finally he reached the guard at the end of the hall speeding up he stretch out his wings as much as possible the guard raised her spear and readied to attack then she blinked. Phantom appeared behind her holding her soul which he quickly popped in his mouth and swallowed.

Meanwhile Ember walk down her hallway while she summoned will-o-wisps to bring the guard at the end of the hallway to her the guard stepped lightly dodging the trap in his trance until he met Ember in the middle who had been dodging the traps set for her still entrance he stepped forward and she leaned in and kissed him for a second before pulling away with his soul in her mouth which she swallowed before burning the body to ash.

"Clear." Both siblings said at the same time which allow Enigma to turn the hall back to normal that's when they saw the guard mare's husk was still standing.

"Brother your wings." Ember said walk past her brother and hitting him in the back of the head with one of her tails.

"Oh right." Phantom said rubbing the back of his head as he closed his wing and retracted his razors and as soon as he did the standing husk was shown to cut cleanly in half.

"One day I will find out who you do that." Said Ember as she and Phantom walked to meet Ash to get their dinner.
