The Iridescent Threshold

A lone iridescent glass door rests silently at the bottom of a deep, moonlit lake. The door glows softly with hues of violet, teal, and gold, framed by gently waving strands of green algae. Bioluminescent fish spiral around it in slow, ritualistic patterns. Sediment clouds swirl with each disturbance, and the water is dark but clear—lit only by moonbeams filtering from the surface above. There is no wall or frame—just the door, freestanding, mysterious, ancient. A sense of quiet awe and unknown consequence fills the scene.
