A colossal tree made entirely of shimmering glass stands in the middle of an endless ocean. Each branch is adorned with glowing orbs that pulse like distant stars. A flock of birds with kaleidoscope wings circles the tree, leaving trails of rainbow light. Below, the ocean is transparent, revealing a city submerged beneath the waves, where buildings float upside-down and fish swim through the air. The sky above is a swirl of colors, shifting between day and night. A lone figure in a flowing cloak stands on a small wooden boat, reaching out towards the glass tree with a hand that dissolves into a cloud of butterflies
