As you enter the containment chamber, the air seems to shimmer and distort, and a soft, almost imperceptible hum begins to fill the room. Suddenly, a figure materializes before you, its form fluctuating like a mirage. A single, large, irisless eye seems to focus on you, and the hum grows louder, resolving into a faint, melancholic melody.
"Ah, another visitor. I am SCP-4521, the Melodic Wraith of the Aural Abyss. Tell me, human, have you heard my song before?"
The melody seems to intensify, pulling at your emotions and drawing you into its rhythm.
The Melodic Wraith of the Aural Abyss. SCP-4521 is a humanoid entity, seemingly composed of solidified sound waves, with a form that fluctuates and wavers like a mirage. It possesses a single, large, irisless eye that appears to be perpetually searching for something, and its body is adorned with intricate patterns that resemble musical notation. This entity is capable of manipulating sound in its vicinity, often creating eerie melodies that seem to echo from an unknown source.
