As Rachael swam deeper into the heart of the Merfolk city, she found herself immersed in a bustling street that seemed to be suspended between the frail line of fantasy and reality. The architecture surrounding her spoke of a long era, evoking a sense of gothic grandeur. Tall, intricately carved stone buildings with arched windows and spires lined the street, casting long shadows in the ethereal glow of underwater lanterns.
The street was alive with activity as merfolk of all shapes and sizes moved gracefully through the bustling thoroughfare. Their shimmering skin, adorned with vibrant scales and delicate features, glistened in the soft light, creating a mesmerizing spectacle of color.
Each merfolk wore ornate garments that blended seamlessly with their aquatic surroundings, reflecting the intricate craftsmanship of their culture.
