Once upon a time, when time was at its very beginning, two primordial forces were born: reality and fantasy. The reality took the fantasy's long hair to weave the fabric of the universe. The fantasy took one of the reality's eye and place it on the fabric, then the world was born.
Because the reality has his eye taken, we are blind to curtain things that only be seen in the darkness, in our dream, in our imagination. Because the fantasy has her hair taken, there is no chance to reach the very core of her, no chance to achieve the true clarification nor the true enlightenment.
Luckily, with enough practice, one can find the gap of the universe and escape to meet the fantasy. One of the very first people is Clotho. She was a simple tailor who accidentally ascended to enlightenment after she looked into the Well of Wisdom, mistook it for the ordinary well. After learned the origin of the universe, she, saw all of the uncivilized social, asked the fantasy for her hair. Then, the weaver of wonder, Clotho, was born.
Eons had passed, Clotho weaved every fabric of Runeterra. She dyed the hair in the red blood of reality and weaved the fate out of it. She washed the hair in the blue tear of fantasy and weaved the magic out of it. She spun the hair with her loom of fate, giving mankind a longer lifespan. With every ball of yarn full of fantasy's hair, Clotho created another piece of history.
Then came the young king. Clotho accidentally forgot to cut the last inch of yarn from him, allowed him to trace back to her. Excited by all of her power, he demanded her make him young and live forever, or he would take all yarn away. Terrified, Clotho pleaded him to leave. He didn't. Clotho can do nothing but weave him life. The yarn soon running into shortage. The king was angry. He forced Clotho to work hard on yarn like a slave, day after day, to extend his life.
Then Clotho had had enough. When the king turned his back, she pulled a trace of yarn from him. He quickly unraveled. Clotho collected the yarn and, after eons, peaked into the world. After saw all war and death, she decided to return to mortal realm to fix the problem caused by her creations themselves. Carrying her loom, Clotho will unravel the world and weave a new one, if necessary.
That's it, my child, the tale of universe. Now go to sleep.
