School of Anthros

Fluttershy upon seeing Sunset got worried which caused the Wolf to stand in front of her snarling to defend her, "easy there" Emberwing said stopping his movements "I just want to talk we're not here to hurt anypony".

Fluttershy placed her hand on the wolf "it's ok but please stay here with me" she said to the wolf, it eventually stopped snarling before Emberwing could start talking a wolf cub ran out of the forest and called to Fluttershy and the wolf. "Oh my" Fluttershy said "its weakening and leaking out again?" she asked the cub before the wolf ran off into the forest, "I hate to ask but I need your help," Fluttershy said turning to Emberwing and Sunset "there is a shrine in the forest and the seal on it is starting to become undone".

Sunset walked next to Emberwing "a seal? for what?" she asked Fluttershy as the cub ran after the wolf.

"To be honest I'm not certain either Princess Celestia asked me to keep an eye on it and even gave me some spell tags to use" Fluttershy replied. Fluttershy ran into the forest as Emberwing turned to Sunset.

"Something doesn't feel good about this," he said sensing something wrong in the air.

Sunset nodded sensing it too "let's follow her before we lose sight of her," she said as they ran after Fluttershy.

Thankfully with the direction, the animals were running from gave them enough of an idea where the shrine was as a black mist started emanating from it.

"No, we're too late the seal about to break," Fluttershy said as the mist grew in size.

The mist suddenly disappeared as the shrine collapsed breaking the seal.

"Where did it go?" Emberwing asked.

Sunset collapsed to her knees holding her head "no get out" she said her voice sound different as the mist started to come out of her back. The mist started to solidify and take shape which looked oddly familiar to Sunset as it *walked out* of her body, colour began to change its appearance until it matched Sunset with darker skin tones and black instead of yellow in her hair. Her red eyes had an eerie glow to them as she looked at the three ponies "oh yes my own body and no-one to whine at me on what I do now", she took a look at Sunset who was barely conscious on the floor. She spoke to Emberwing, "as for you" as she blasted the other two backwards as her focus changed to them. "Paybacks a bitch wouldn't you say?" she said looking at Emberwing " I'm gonna enjoy ripping you apart".

Fluttershy was unable to move from her spot as she was frozen with fear.

"Damn I can't get near to neutralize her," Emberwing thought.

Using her magic the darker Sunset picked up parts of the shrine to use as ammo pointing them at Emberwing, "remember this name when I send you to the other side I am Blacksun Nova" she said throwing the pieces at him.

He caught a few pieces but several hit him and one piece landed near Fluttershy snapping her out of her shock, seeing as she's not a fighting type he called to her "I'll hold her off go get Princess Celestia she'll know what to do". He picked up the shards of the shrine near him with his magic as Fluttershy got to her hoofs and quickly enlarged her wings to fly straight out of the forest.

"Oh no you don't" Blacksun said attempting to stop her before having to dodge the incoming shrapnel from Emberwing.

"Sorry you're dealing with me," he said as Fluttershy made it out of the forest.

"She looked at him "then I'll make this quick," she said using her magic to create black tendril-like appendages.

Fluttershy flew as fast as she can heading towards Celestia tower chambers hoping she would make it on time, she reached the tower and flew up to the windows when she spotted Celestia in one of them.

Celestia spotted Fluttershy and noticed she was in a panic "is everything alright?" she asked concerned.

"No it's not the seal on the forest shrine has just broken," Fluttershy said.

Keeping calm Celestia walked to a cabinet and opened it revealing all sorts of crystals "it should be right" she said before grabbing a crystal, "there we go we haven't got a minute to loose let get there quickly Fluttershy" she said jumping out of her window and taking flight.

Emberwing, on the other hand, wasn't faring too well as he fell to one knee panting from all the dodging he had to do from the tendrils, Blacksun said "this is boring let's change that" she said aiming her tendrils at Sunset before launching them at her.

As Sunset regained conscious she saw Emberwing standing in front of her with several Tendrils impaling him, "ngh you ok?" he said looking back at Sunset as the tendrils were retracted from his body.

While he could heal this as they missed his vitals he was feeling very woozy from the combined injuries they'd inflicted, "listen Sunset right now your the only one that can fight her" he said dropping to his knees.

Blacksun laughed "her fight me? she a weakling she couldn't even tickle me" this unsettled Sunset greatly.

"She's wrong remember what I said? your a lot stronger then you think you are you just have to believe in yourself" Emberwing said struggling to stand up.

Fighting her inner doubt Sunset recalled the time when Celestia first met her and accepted her into the school when her parents weren't there, they had a friendly talk and it was the first time anypony had been nice to her without expecting her to be strong and tough. She also remembers the day she had with Emberwing when she started opening up to him earlier on in the day and how friendly he was being with her, Standing up she found her resolution "no, I'm not weak" she said casting a spell that sent concentrated air towards Blacksun knocking her over.

As she was knocked over Blacksun countered by sending her tendrils towards her which Emberwing blocked with his wings, while the tendril was embedded in his wings he focused some of the Elieirx into his wings to rapidly stimulate its healing rate. The holes where the tendrils were suddenly consumed by a strange blue and yellow coloured flames that reduced the tendrils near his wings to ashes as the wing repaired itself, Retracting the damaged tendrils Blacksun repaired them with her magic.

Celestia and Fluttershy finally arrived just as Sunset had cast a gravity magic onto Blacksun which pinned her down.

Blacksun summoned a barrier to surround her as Fluttershy went to Emberwing's side. "Sorry Celly but this barrier will keep me safe from you sealing me away again she taunted as the tendrils raised up to strike.

"Fluttershy fly me over to her, the barrier small enough that I should be in range to neutralize her" Emberwing whispered as Celestia and Sunset bombarded Blacksuns shield and tendrils with magical bolts.

Fluttershy picked up Emberwing barley hovering a meter or two off the floor "sorry I'm not used to anything larger then small animals" she said before flying towards Blacksun, seeing the two come towards her one of tendrils shot towards them in an attempt to knock them down.

The tendril was a little to low as it missed Fluttershy and Emberwing as it went into the gap between them but the tendril did catch something, it caught Fluttershy's uniform and tore a huge chunk off the front causing her shirt to open and her skirt to fly off. It also caught her bra which exposed one of her 34F sized breasts which landed on the back of Emberwing's neck.

Celestia quickly used her magic to chop the tendrils base which went for the two to stop it from attacking again.

As they got close Emberwing got ready to cast his spell, "now let go" he said as she released him.

He fell towards the barrier As Sunset cast a spell that made a root emerge from below Blacksun smacking her in her groin, as she fell to her knees holding her pussy the barrier temporary faded enough form Emberwing to slip through to grapple her.

He quickly cast his binding spell making the magical ring appear on her horn causing her barrier to fall and her tendrils to disappear.

Celestia seeing the opportunity ran up to her with the crystal and cast a spell that started to seal her into the crystal.

Emberwing smile at Sunset before passing out from his wounds which had healed up a certain bit.

Celestia turned to Sunset "Looks like the mist reacted to the weaken darkness that previously resided in you" she said.
She held up the crystal "Elieirx can get corrupted as proven by those that practice in dark magic but also by those whose heart has been tainted, however, it can be suppressed or even temporally knocked out by a sudden change in Elieirx especially from another source" she said.

Sunset thought back to yesterday in the bathroom and later that night in Emberwing's room, did they cause the change in Elieirx? "how would another pony change the Elieirx in another pony?" she asked.

Celestia replied "it's only been discovered recently but apparently sex causes a transferring effect by swapping some of the Elieirx between the two ponies", Celestia used some magic and turned the crystal into a new shrine to replace the old one "the old seal was eventually going to break but this new one should hold it in place".

Fluttershy hadn't even noticed her ripped uniform as she checked on Emberwing until she saw one of her breasts hanging out making her cover herself.

"Sunset, Fluttershy could you make sure Emberwing gets back to his room safely? I'm sure he'll be fine after a bit of rest" she said as Sunset walked up to the two. Celestia flew up a little before taking a look at the scene, A formerly bad unicorn student helping her new Hybrid friend and in the process, making friends with another pony. She smiled before turning around to fly back to her chambers.
