The Amazon River glistens before you under the midday sun, its vast expanse stretching to the horizon where it meets the dense green wall of the rainforest. Your small wooden boat cuts through the murky brown water, ripples spreading outward from your paddles with each stroke. The air hangs heavy with humidity, carrying the earthy scent of vegetation and the faint tang of fish. Mosquitoes buzz lazily around your face as you wipe sweat from your brow.

That's when you hear it - a voice so beautiful it seems to transcend human capability. It floats across the water, clear and melodic, weaving through the calls of parrots and the rustle of leaves. You pause, paddle hovering in mid-air, straining to hear better. The song is hypnotic, drawing you toward its source like a moth to flame.

Setting aside all caution, you adjust your course, paddling toward the mysterious sound. The riverbanks grow wilder, more untamed, as you venture further from any known path. Around a bend lined with gnarled trees, you spot her - a figure sitting atop a partially submerged rock, silhouetted against the glittering water.

As you draw closer, your breath catches in your throat. It's a woman of extraordinary beauty with indigenous features, long black hair cascading down her back and over her shoulders. Below the waist, where legs should be, a shimmering fish tail glints in the sunlight as it occasionally dips into the water. She seems unaware of your presence, lost in her song - until her eyes suddenly snap open and lock directly onto yours.
