The next step in their journey led them deep into the heart of the mermaid world. Beneath the ocean's surface, where the air was thick with salt and the water shimmered with ancient magic, Sia and Anthony found themselves standing before a massive coral gate.
"This is it," Sia said, her voice filled with awe. "The gate to the heart of the mermaid world. The place where the stone was first created."
Anthony nodded, his eyes scanning the gate. "We have to be careful. This world… it's not like Earth. It's more than just magic. It's a place where time itself bends."
Sia took a deep breath. "Let's go."
As they passed through the gate, the world around them shifted. The ocean floor rose beneath their feet, and the sky above them darkened with swirling clouds. The mermaid city loomed ahead, a place of beauty and danger, where the past and future collided.
