Corruption

Prologue

"What in Equestria..." A dark furred alicorn stated bluntly, her coat sparkling elegantly in the sunlight that shown through the stained glass window's. She looked to her sister in confusion.  "What just happened??" A beautiful white pelted alicorn stood next to the black mare, the same surprised expression upon her face.

"Luna, my dear sister, I... Don't know..." The white alicorn, or Celestia, replied, sounding slightly disappointed a the fact that she didn't hold an answer. The older sister took a step toward the pedestals which held the Elements of Harmony. Staring at the necklace that held the Element of Laughter, Celestia shook her head, trying to grasp what had just happened right before her eyes.

"Why did it change?" Luna asked, voice shaky, something that was out of character for the younger princess.

"I told you, I don't know!" Celestia yelled, whipping around to face her sister. Luna flinched backwards, practically shrinking down to half her size. Her body seemed to seize up with sudden fear from her companion's unnatural snarl. A sigh rippled through the bright coated alicorn as she coed to her younger sister, anger turning to concern.  "I guess I'm as clueless as you are..." Both alicorns turned back to the Element of Laughter. An uneasy feeling came over Luna upon looking at the necklace, forcing her to stare down at her hooves. The castle around her suddenly seemed foreboding and cold.

"I-I can't look at it..." She stuttered, a shiver gripped her body and shook it to the core. Luna could feel her sister's questioning gaze on her, making the situation more uncomfortable. Without waiting for a response, she repeated, "I just can't look at it!" And with that, she sped out of the room and out of sight. Princess Celestia returned her eyes to the Element and shuddered.

There, was the balloon. That was normal... But the disturbing part was that on said balloon, were two eyes scrunched up in a terrified squint and a mouth that seemed to be screaming in agony.
