**Chapter 1: The Fateful Voyage**

The dark blue waters of the fjord churned and foamed as Iduna's ship battled against the raging storm. She stood at the helm, her long brown hair whipping about her face, her eyes fixed on the horizon. The winds howled and the waves crashed against the vessel, threatening to capsize it at any moment. Iduna's grip on the wheel tightened as she struggled to keep her ship on course. She had set sail for Ahtohallan, driven by a desperate need to understand the mysterious powers of her daughter Elsa. The wise words of the ancient river seemed to be her only hope in unlocking the secrets of her daughter's abilities. As the storm intensified, Iduna's ship creaked and groaned under the force of the waves. She felt a jolt as the vessel lurched violently to one side, and her stomach dropped as it seemed to hang suspended for a moment before righting itself. The sound of splintering wood and cries of alarm filled the air as the ship took on water. Iduna's world went dark as she was washed overboard, the icy waters closing over her head like a shroud. When she came to, Iduna was disoriented and battered, her head pounding and her body aching all over. She lay on a sandy beach, her gaze unfocused as she stared up at the grey sky. The wreckage of her ship littered the shore, a grim reminder of the disaster that had befallen her. She struggled to sit up, her movements slow and labored, and took stock of her surroundings. She was alone. The beach was deserted, with no sign of her crew or any other survivors. Iduna's heart ached with a mix of grief and fear as she scrambled to her feet, her eyes scanning the horizon for any sign of life. The storm had passed, leaving behind a eerie calm, but she knew she couldn't stay here for long. She had to find help, and fast. As she stumbled along the beach, Iduna spotted a group of people in the distance, their faces dark against the pale sky. She waved her arms, hoping to catch their attention, and they turned towards her. A mixture of curiosity and suspicion played on their faces as they approached her. Iduna's instincts told her to be cautious, but she had no choice. She had to trust these strangers if she wanted to survive. The group closed in around her, their leader, a burly man with a thick beard, eyeing her warily. "Who are you?" he growled, his voice like a challenge. Iduna hesitated, unsure how much to reveal. She decided to play it safe, for now. "I'm...I'm a traveler," she said, trying to sound as non-threatening as possible. "I was shipwrecked. Can you help me?" The man's expression softened slightly, and he nodded. "Come with us," he said. "We'll take you to our king. He'll decide what to do with you." Iduna nodded, her heart pounding with uncertainty. She had no idea what lay ahead, but she knew she had to take a chance. She followed the group, her eyes fixed on the backs of her new captors, as they led her away from the wreckage of her ship and into the unknown. The group walked in silence, their footsteps echoing off the trees. Iduna's mind was a jumble of thoughts and emotions, her body aching and her spirit battered. But she refused to give up. She had to keep moving, for herself and for her daughters, Elsa and Anna, back in Arendelle. Little did she know, her journey was only just beginning, and it would lead her to a place of refuge, and a young prince in need of her help.
