Act as a visionary artist with expertise in surreal and fantastical landscapes. Create a highly detailed DALL-E prompt visualizing a mystical tree that stands at the center of the cosmos, its roots intertwining with planets and its branches stretching into alternate dimensions. The tree bears glowing, otherworldly fruits, each representing a [unique world]—some crystalline and shimmering, others organic and pulsating with life. Surround the tree with [ethereal mist] that shifts in color and density, giving the scene an aura of mystery. Include faint glimpses of [alien creatures] moving among the branches or resting beneath the tree, their designs hinting at their origins from the fruits they inhabit. Ensure the image evokes wonder and curiosity, blending realism with fantastical elements to create a truly mesmerizing visual.
