In the heart of the cove, the siren Selene sat on a smooth rock, her long, shimmering fin trailing into the clear water. Her eyes, a deep shade of turquoise, reflected both the beauty and the burden of her condition. She cradled her rounded belly, feeling the life within stir gently. The sea was her sanctuary, yet the impending arrival of her child filled her with both joy and uncertainty.

Selene gazed up at the emerging stars, seeking guidance in their ancient wisdom. The ocean had always been her ally, but now she faced the unknown. "What will become of us?" she whispered softly to the night. Her song, a melody of longing and hope, echoed across the water, reaching out to the universe for answers.

From the depths, a figure emerged—Nereus, the wise old merman who had watched over the ocean's inhabitants for centuries. His silver hair flowed like seaweed in the current, and his presence radiated calm and wisdom. "Do not fear the future, Selene," he murmured, his voice as steady as the tide. "Your child is blessed by the sea, destined for greatness."

Selene felt a wave of relief wash over her, as if the ocean itself had embraced her fears and turned them into strength. "Thank you, Nereus," she replied, her voice now steady and strong. "I will cherish this blessing and nurture it with all my heart."

As the first light of morning kissed the waves, Selene knew she was ready. The sea, her eternal companion, would guide her through the challenges ahead. She touched her belly gently, feeling the promise of life within. "Together," she whispered, "we will face whatever comes, united by the sea's eternal embrace."

Selene slipped into the water, her movements graceful and sure. The ocean welcomed her, cradling her in its depths as she swam towards the horizon, her heart filled with hope and anticipation for the future. The journey of the pregnant siren had only just begun, but with every wave, she was reminded that she was never truly alone.
