Author's Note: So, this is finally the full-length story of my OC, Eris, the Muse of Chaos. Her "teaser" was the one-shot "A Little Bit of Chaos", which contained her League Judgement. You are welcome to read that if you wish, but it's not really needed to get what's happening in the story.

Anyways, enjoy the story!

Prologue:

Her chakrams at her hips, she climbed the stone stairs to the elegant but domineering building, sweat, dust, and dirt forming a thin layer over her robes. Under the blanket of stars, the famed Institute of War was bathed in an eerie glow, the large blue crystals atop the colossal square columns illuminating her every step.

This was the only place she could go now. Even then, she doubted their means of protection. Would they even accept her once they found out who she was?

A flicker of movement caused her to throw her weapon at lightning speed, the other held ready in her left hand. The chakrams sliced through the air and embedded itself in the surface of one of the columns with a loud thwack.

She narrowed her eyes at the expanse of rock. Still here…somewhere.

When no other movement caught her eye, she walked towards the column and, with a little difficulty, pulled her weapon out. It left a thin scar on the surface, small cracks lining its sides like veins. Glancing at the shadows the columns cast, she resumed her climb up the steps. A hooded figure seated behind a desk near the door looked up as she reached the last step, his face unseen. Before him lay an open notebook, a pen ready in his hand.

She approached the hooded figure. "I wish to join the League."

The hooded figure nodded and stood. "Come with me."

Puzzled at the fact that he did not even ask her name or purpose, she followed him through the great doors of the Institute of War. She looked around in wonder and lowered her hood. The Great Hall could easily fit a mansion within it, with doors to her right and left, leading to the other rooms. The hooded man beckoned to her and gestured towards the massive doors at the other end of the hall.

"Do you not want to rest from your journey?" he asked her. "Judgments are sometimes…very taxing on those who want to be Champions."

She shook her head. "No. I want to do it here and now."

He shrugged. "Very well, don't say I didn't warn you. When you are ready, go through the double doors."

"Thank you," she said.

She approached the doors slowly as the hooded man left, feeling slightly nervous. Her hands went to the chakrams at her hips, her fingers lightly brushing over the sides of the blades. A single sentence was carved in curling script upon the marble surface of the doors:

The truest opponent lies within.

Smirking and feeling more confident, she pushed the doors open. A gust of wind blew through her, but within the chamber there was nothing but darkness. She straightened her robes.

Now or never.

Without looking back, she entered the Reflection Chamber.

Welcome to the League of Legends, Muse of Chaos.
