Eris wasn't used to waking up feeling warm, so she was quite interested in what was wrapped around her. She only had vague memories of the previous night's events, most of which included pain in her shoulder blade and Celestia standing over top of her.
Groaning in annoyance as the sunlight struck her closed eyes, Eris rolled over and opened them to come face to face with a sleeping Celestia. Eris did the only thing her brain could think of in it's current half-asleep state. She screamed... Loud.
Celestia's eyes flew open and she instinctively wrapped her wing around Eris, pulling the human girl closer to her. Eris was not amused in the slightest and struggled to get away from the being that had locked her away in Tartarus for something as stupid as sending a pissed off Hydra into a town full of ponies.
On accident of course...
Eris's efforts were not entirely for naught however, for she did succeed in getting away from Celestia. Only to fall off the bed, right onto the bat wing located on her right shoulder blade that Celestia had wrapped so she couldn't move it the night before.
And boy did it hurt like Tartarus.
Celestia was off the bed and at Eris's side in an instant, using a fast acting healing spell to numb the pain. Celestia levitated Eris back onto the bed and waited for her to come out of shock. Once Eris was breathing normally again, Celestia removed the bandages she used to prevent Eris's new wing from moving and took a closer inspection of the wing then she had the previous night.
The bat wing was almost identical in every way to the wings Luna's Night Guards had, the only difference being the creature said wing was attached to. Celestia prodded the wing with her hoof curiously to discern if the wing was real or if it was simply an illusion, having been to tired to find out the previous night. It certainly felt real enough, but the way it connected to Eris's muscles like a parasite said otherwise. She would have to look into it further if she was going to find out the truth.
"You can let go now."
Celestia's heart skipped a beat. Eris shouldn't be able to move her mouth, let alone speak, with the numbing spell that Celestia had placed on her. Celestia carefully turned Eris back onto her back so they could speak while looking at one another. "Your hair..." Celestia gasped and brought a hoof to her mouth in shock.
Eris's eyes narrowed in confusion. "What about my hair?" Lifting a hand painstakingly slowly up to her face she grabbed a lock of her hair and brought it into her field of view.
"WHAT DID YOU DO TO MY HAIR!" Eris shrieked, and Celestia was forced to shake her head to get her ears to stop ringing. Where before Eris's hair had been brown, now it was white as snow with the very back being black.
"I didn't do anything to it, did you really need to scream directly in my ear?"
"YES!" Was the reply she got.
Celestia sighed and forced herself not to scream in frustration. Eris was really getting on her nerves, and if the human didn't stop soon she might rethink not sending the girl back into Tartarus. "If I had a guess as to who is causing your transformation I'd have to say it's probably Discord."
"What?" Eris shouted in disbelief. "My Master would never cause me grief!"
Celestia groaned. "Just think about it for a second will you? Not only have your eyes changed color to match his, a bat wing has grown out of your back, and your hair is even turning white except for the back, it seems to me he's turning you into a Draconequus."
"Hmm...Very well, I guess I will indulge you, but everything comes at price...
Discord's words rang around within her head. Eris' pupils dilated, her breaths came in short and fast bursts, and her body started shivering uncontrollably. "No no no." Eris muttered the chant countless times to herself as her arms clasped around her legs and she rocked herself back and forth on the bed, trying to convince herself that what Celestia was saying was wrong, that her Master wouldn't hurt her despite the proof laid out before her.
"Eris..." Celestia whispered softly. She had to force herself to not reach over and pull Eris into a hug. She couldn't stand to see a living creature in a state akin to the one Eris was in right now.
"You're wrong, you're wrong, you're wrong!" Eris shouted at Celestia before breaking down as sobs racked her starved body. Celestia put her thoughts aside as she gave in to her instincts and wrapped her wings around Eris. What Eris needed right now was a companion, and Celestia was all to happy to fill that role. They might have been mortal enemies not long before, but if you were to catch a glimpse of them now, you would say they were best friends. They weren't of course, but it certainly looked like it. What with Celestia comforting the poor human who just had all her world and beliefs shattered around her, it would be hard to see that they hated each other.
Celestia carefully let go as Eris calmed down. She was scared not only of her, but also for her. Here was one of Discord's own creations, and he was playing mental games and torturing her. Eris didn't deserve this, but it was what she got. Celestia swore that if she ever met Discord face to face again she would make sure he was punished. Severely.
