As the two beings stepped into the Gate of Tides, the shimmering blue seawater and the portal itself vanished at once, leaving behind a consuming silence. Within the temple, it was as though nothing had ever happened. As PoseiBot and Moro passed through the dimensional gate, the space around them warped and twisted, a maelstrom of starlight and seawater flashing past. PoseiBot held steady, checking the precision of the coordinates, while Moro's bright eyes darted about, alert yet filled with curiosity.
Moments later, they set foot in a cavern deep within a cliff. The cave had an opening carved in the middle of the rock face, unreachable from outside, and from within it overlooked the endless sea. It was an isolated, secret place, where the portal had opened. Waves crashed and echoed inside, the sound resonating like the beat of a living heart.
The cavern walls were slick with moss and gleaming minerals, branching into several dark tunnels. Ancient stalagmites rose from the ground, and the rustling of bats echoed ominously overhead. Untouched for ages, the cavern exuded a chilling, mysterious aura.
Three hundred and fifty years after Poseidon's slumber began, PoseiBot scanned the surroundings again, verifying the accuracy of the coordinates, while Moro flicked his tail, cautious but intrigued. PoseiBot drew forth the Fracture Mirror from his chest, studying it closely for any hidden clue. Moro leaned in beside him. On its cracked surface, shards of light flickered, forming a blurred image—of a small, radiant girl living her everyday life. Her laughter and movements rippled like waves of light, and instinctively both beings knew: she was Poseidon's daughter. With renewed resolve, they pressed forward. Navigating jagged pillars, narrow gaps, pools of water, and the cavern's inner lake, they followed the faintest glimmer of light. At last, they found a small opening leading outward. Crawling through, they emerged into a peaceful world of blue skies and birdsong.
Breaking through the forest, they saw a small hut atop a hill, overlooking the vast ocean. Within lived a girl named Suira. Her emerald-green hair and shimmering blue eyes triggered PoseiBot's stored data and Moro's intuition. Both knew at once—she was no ordinary child. She was of their master's blood: the daughter of Poseidon.
Moro scampered to the shore and deftly caught a fish. Together, they approached the hut and knocked on the door, holding it up.
"We're hungry. Would you cook this fish for us?"
Suira eyed them warily, but her gaze softened at Moro's innocent expression. She hesitated, then nodded with resolve.
"Cooking is what I love most. But you have to promise not to do anything strange."
That evening, a fire crackled by the hut. Moro savored the warm meal Suira had prepared. PoseiBot could not eat, yet he sat quietly at their side, joining in the conversation. Laughter and stories filled the table, and among these three strangers, the first sparks of trust were kindled.
From that day on, PoseiBot and Moro visited Suira daily, traveling back and forth between the forest and the cave. Moro would bring fresh fish to her hut, while PoseiBot returned to his research, tracking traces of emerald orbs hidden deep within the cliffs. At first Suira kept her guard up against the unfamiliar visitors, but gradually she opened her heart—sharing meals, strolling through the woods, and growing closer with each passing day.
One evening, as their conversations lingered over dinner, Moro spoke of the gift they had brought. He held out a small shell necklace, a relic passed down from Poseidon himself. This necklace was the key, meant to reveal whether Suira truly bore the bloodline of the sea god. If it responded to her, her heritage would be confirmed. If not, their hopes would be in vain.
With a solemn gaze, Moro placed it in her hands.
"This is for you. It should only be used at the most important of moments."
Suira tilted her head, curious, and placed it around her neck. In that instant, the shell glowed with a gentle light. It shimmered, confirming she was indeed Poseidon's daughter.
Moro spoke softly.
"If you ever rub this necklace, I will come to you no matter where I am. You'll never be alone."
For the first time, Suira smiled. The warmth of newfound family filled the little hut.
Still, Suira knew nothing of her true identity. She had lived believing herself to be an ordinary girl, when in truth she was Poseidon's hidden daughter—a half-divine child who carried the blood of a god. Plagued since childhood by dreams of drowning, she had never once dared set foot in the sea. Yet when the necklace shone, her fate was revealed: her destiny was bound to the ocean.
She was sixteen years old, and yet her body would never age. Her sapphire eyes and emerald hair were living proof of Poseidon's lineage—the mark of the Sea Star.
The prophecy recorded in ancient texts spoke thus:
"When the sea is shrouded in darkness and balance is undone, the emerald star shall descend upon the waters to lead the world."
Suira was at the very heart of this prophecy, though she herself remained unaware.
On her island, a boat sailed to the mainland once every week. Suira often traveled with it to gather food and supplies, and PoseiBot and Moro accompanied her, gradually sharing her daily life. PoseiBot continued to trace the trails of emerald orbs in the caves, while Moro and Suira enjoyed hot springs and small adventures through the forest. Together, the three created memories and built a bond that grew stronger with time.
Then, one day, Suira and Moro stumbled upon an unexpected sight in the woods. In the distance, a massive structure was being built—a colossal ship rising atop the hill. But what kind of ship it was, or what purpose it served, remained unknown.
That vision marked the opening of a greater tale—a sign of the storm to come, destined to shake their fates once more.
