Kymopoleia gripped her silver trident and tried, for the fourth time, to hold the storm inside her chest. She wanted mastery. She wanted to be feared enough that her father could never trade her again, the way he traded her to a hundred-handed giant she called a monster. So she stood alone in an empty training hall beneath the palace and reached for the power that lived in her grief. The aquamarine crystals along her scepter flared. Then the storm tore loose anyway. The current slammed her into the wall. Pain cracked up her arm. Above the waves, she knew, ships would be breaking. She was the goddess of violent sea storms, and still the storms ruled her instead. Her hands shook. A thin line of blood drifted from her lip. No one in Atlantis had ever taught her to hold the power. No one knew how. Her father had given her the curse and left for Olympus. Her mother ruled in his place and had no answers. The hall doors opened. An old teacher entered, half man and half horse, with the tail of a great fish trailing behind him. Sophronios Bythoson had trained the armies of Atlantis for longer than she had been alive. He carried his bronze spear and watched the water still churning around her. "You fight it like an enemy," he said. "That is why it wins." Kymopoleia wiped her mouth. "It is an enemy. It hurts me every time." "It hurts you because you clench against it." He moved closer, slow, careful. "I taught your father's soldiers to breathe through fear, not swallow it. Your storm is fear and grief. Stop damming it. Let it move through the trident instead of through your body." She wanted to argue. Instead she lifted the scepter again. The old fear rose, the memory of her wedding, the giant's many hands. The storm answered. This time she did not fight it. She breathed, the way he said, and pushed the feeling down the shaft toward the three silver prongs. The water screamed past her. The crystals blazed. But the power left through the trident, not her chest. The hall shuddered. A column cracked. Yet when the current settled, Kymopoleia was still standing. Unhurt. For the first time, the storm had obeyed. She stared at her own hands, steady now. "You have a teacher," Sophronios said. "If you want one." Kymopoleia bowed her head. "I do." He nodded, but his face stayed grim. "Then understand what you have agreed to. The men above will ask why ten ships sank tonight. Your mother will ask. And once they learn you can aim this power, they will fear what you might aim it at." He turned toward the doors. "Power that no longer wounds you is power others will try to control. Rest tonight. Tomorrow, the questions begin."

The morning after her first true mastery, Kymopoleia could not go back to the training hall. Guards lined its doors now. Her mother's eyes followed every current near the palace. If she practiced under watchful stares, someone would see what she could do, and fear would follow. Sophronios had warned her. Power others could see, they would try to control. She needed a place with no eyes at all. She slipped out of Atlantis before the glow-coral woke. A school of fish scattered as she swam past the city's edge, their bodies flashing silver and gold. She kept going, past the market gate, into dark water where no patrols reached. She was looking for somewhere her storm could scream without a witness. Far out, the seafloor dropped away. A volcano rose from the dark, its black sides split by glowing cracks. Lava bled from the fissures in slow orange ribbons. The heat warped the water. No guard would follow her here. No fish lingered. It was empty and ugly and perfect. Near its base lay a shipwreck, a broken hull half-buried in ash. Torn timbers jutted up like ribs. Kymopoleia circled it. The dead ship meant no one sailed these waters. She had found her secret place. She lifted her trident and let the old grief rise. The giant's hundred hands. Her father's cold decree. She breathed, as Sophronios taught, and pushed the feeling down the shaft toward the silver prongs. The aquamarine crystals blazed. The storm poured out of her and struck the wreck. Timbers exploded. Ash boiled up in a black cloud. Kymopoleia stayed standing. Unhurt. She laughed, shaking, and did it again. Harder. The current tore through the hull and slammed into the volcano. A fissure cracked wider. Lava gushed free, brighter than before. She stopped, breathing hard. The wreck was ruins now. But the volcano groaned. The ground shuddered under her. The crack she had split kept spreading, and more lava spilled out, climbing toward a vent above. She had not just practiced. She had wounded the mountain. A deep rumble rolled through the water. Kymopoleia backed away. Her secret place held fire she did not understand, and she had just fed it her storm. If the volcano burst, the quake would travel. It would reach Atlantis. And if her mother felt the sea shake, she would ask what caused it. Kymopoleia stared at the widening glow. She had her hidden ground at last. But she had woken something under it, and now she had to choose: flee and hope the mountain settled, or stay and learn to aim her power before it tore the trench open. She gripped her trident tighter and turned back toward the fissure.
