We need a story, some plot... What kind of magic the world has by now?
Edit: No, this is not right way. Can I do something like that, or would it be universal and impossible to do?
[] Words of Power
After his rebirth, one of the Artist's initial endeavors was to play with Mystical Yarn and Little Gods. He had a brilliant idea to assign a unique name to each little spirit. These names were incredibly simple, so small and delicate that they seemed impossible to pronounce separately. Nevertheless, they were distinctive - the Artist ingeniously devised a unique name for every tiny spirit, often doing so in his spare time. This ensured that each Little God could remember, recognize, and respond to its own name in the simplest way possible. However, the Little Gods were not solitary beings; they were all integral parts of a greater whole, harmoniously interwoven fibers in the Mystical Yarn.
Through this interconnectedness, individual words transformed into complete sentences when many Little Gods accidentally heard their own names and responded. It was not that someone intentionally uttered these names, but rather the names were so minuscule that they could easily be misheard in any surrounding information. Thus, certain strands of the Mystical Yarn began to vibrate randomly, producing 'noises' as the Little Gods heard their names in meaningless things and answered. This white noise had no impact on the world, as its chaotic nature caused the voices of different spirits to cancel each other out.
However, the Artisan became intrigued by these noises, these waves and vibrations. He endeavored to weave the threads in such a way that the voices of many spirits, upon responding to their names, would create not white noise, but a harmonious melody that made sense. Yet, playing this instrument proved challenging, requiring extensive experimentation. After all, the names of the spirits were so small that even the thoughts and mood of the one attempting to play the strings influenced the outcome. Consequently, the majority of words and gestures only resulted in fleeting bursts of harmony, a faint sensation for those around, before devolving into meaningless and ineffectual white noise that failed to influence the world once again.
Only by forging a special Spark for himself could the Artisan work more effectively with these waves, deciphering rare stable and meaningful vibrations amidst the chaos. Upon completing this monumental task, the Artist approached his mother and siblings to showcase the fruits of his labor. The Artisan gestured with his paw and snapped his fingers, causing his strings to utter the word [Lux], and a light ignited at the tip of his talon. This light continued to burn as the string vibrated, resonating with the echo of the spoken word. While the Artist's relatives possessed the ability to create light at will, it was the ingenuity with which it was achieved that mattered, rather than the end result. And thus, the Words of Power were born, and the Spark of Magic was forged and offered to the Great Tapestry. This would allow anyone who possessed the will, intelligence, patience, and fortune to potentially make their own strings find and sing these Words. There were many of them, with their own specific meanings and effects to find in the chaos of white noise.
Edit: Keep in mind that each word is a separate spell with certain strict limits on what it can do without destabilizing and turning back into white noise. Like [Lux] can only create a point source of light that can be dimmed/brighten within specified limits, and which color is usually gilded and can only be changed to slightly more white or orange. Step to the left, step to the right and the singing of the string becomes a meaningless noise, interrupting the effect. It also means that you can't just take and pronounce words one after another or together to create some new effect - in most cases you will get white noise again and nothing for an effect. If you need a beam of light, there are two ways: exhaustively looking for a word that creates this particular effect (if it exists at all), or exhaustingly searching for a word that will harmonize with another to create a similar effect (if it exists at all). Creating a new spell is an extraordinary job that relies more on luck and stubbornness than knowledge.
