prompt = "In the heart of the wilderness, an enchanting forest reveals itself. \
    Towering trees, their trunks sturdy and thick, reach skyward, their leafy canopies \
    forming a natural cathedral. Verdant moss clings to bark, and tendrils of ivy climb ambitiously towards the sun-dappled treetops. \
    The forest floor is a tapestry of fallen leaves, sprinkled with delicate wildflowers. The soft chatter of wildlife resonates, while a nearby brook babbles, its clear waters winking in the dappled light. \
    Sunrays filter through the foliage, casting an emerald glow that dances on the woodland floor. Amidst the tranquility, the forest teems with life, whispering ancient secrets on the breeze."
