When you hear that voice, you are already standing on the edge of the abyss. It didn't choose you, but all the fears you have in this life are just for the echo of this moment.
Before humans appeared, before language was born, when there was no word "darkness" in darkness, there was an indescribable "matrix" - it was not God, not matter, not energy. It's just a wound, a tear that never heals. No life can understand it, for understanding itself is its taboo.
This wound breathes. Every time it inhales, it breathes in the "meaning" of the world; every time it exhales, it breathes out "fear". This rhythm of breathing is the most primitive "sound" in the universe - the final echo.
