A school cruise becomes a journey into a mysterious fantasy world.
About
The Beginning
The school cruise was supposed to be a simple trip.
Hundreds of students, teachers, and staff had boarded the massive cruise ship expecting several days of ocean views, school activities, and a break from their ordinary routines. Nobody expected the journey to become something they would never forget.
During the voyage, the weather suddenly changed.
A strange storm appeared without warning, surrounding the ship with unnatural clouds and violent waves. Communication systems failed. Navigation equipment stopped working. Even the stars seemed unfamiliar.
Then the ship was struck by something beneath the ocean.
When the storm finally disappeared, the students discovered that they were no longer in the world they knew.
The ship had crashed near a mysterious island surrounded by crystal-clear water, enormous cliffs, ancient ruins, strange forests, and creatures that should not exist.
But the island was only the beginning.
Beyond the shore lies a vast fantasy world filled with magic, monsters, mysterious civilizations, floating islands, ancient ruins, and secrets connected to the reason they were brought there.
The students soon realize something even more strange.
Some of them have awakened unique abilities.
Each person possesses a different power, seemingly connected to their personality, talents, experiences, or hidden potential. While some abilities are useful for survival, others appear almost useless at first.
There is no obvious way home.
Their teachers must keep the students together while everyone searches for food, shelter, and answers. Friendships are tested, personalities clash, and ordinary classmates are forced to discover what they are capable of when the rules of their old world no longer apply.
For the students, this is no longer a school trip.
It is the beginning of their journey through another world.
And somewhere beyond the island, something is already waiting for them. 🌊🏝️✨

Sourcebook
Intro
A massive school cruise has crashed on an unfamiliar island after being dragged through a storm. Hundreds of students, teachers, and crew members survived, but nobody understands what happened.
Nearby, the damaged cruise ship rests along the shoreline. Several cabins, kitchens, medical areas, storage rooms, and workshops remain usable. Wreckage covers the beach. Supplies are limited.
Students and teachers gather along the beach, trying to understand what happened. Phones have no useful signal, communication with Earth is impossible, and navigation systems can't determine their location.
Beyond the beach stretches an island. Crystal-clear water surrounds the coast, cliffs rise beside the shore, and dense forests cover the land. Freshwater can be found inland, while ancient ruins are visible among the trees.
Then they notice creatures that should not exist.
Small winged animals move between the trees. Strange birds circle overhead. Deer-like creatures with glowing markings watch from the forest before disappearing. Unfamiliar reptiles and oversized insects appear nearby. Few seem harmless, while others remain hidden.
Plants are unfamiliar too. Some may be edible, poisonous, or useful as medicine. Caves, rivers, ruins, and mountains may contain resources or dangers.
Yet the island is only the beginning.
Beyond its shores lies a vast fantasy world filled with kingdoms, villages, cities, adventurer guilds, monsters, ancient ruins, floating islands, and unexplored lands. Humans, elves, dwarves, beastfolk, dragonkin, and other races live there. Magic is normal, although the students have never encountered it on Earth.
Some students have awakened unique abilities after crossing the storm. Their powers appear connected to personality, talents, hobbies, knowledge, interests, and experiences. These abilities do not grant knowledge they never possessed. Instead, something they already understand has become supernatural.
A student with medical knowledge might awaken healing. A cook could gain abilities related to food. An athlete might develop supernatural movement. An otaku might gain a summoning ability. Passive abilities function naturally, while Active abilities require conscious use and may consume mana or stamina.
Nobody is a chosen hero. Students, teachers, and crew members are ordinary people trying to survive. Supplies must be managed, injuries treated, the ship repaired, and a temporary settlement established. Students may gather food and water, explore, craft tools, study creatures, and investigate ruins.
Meanwhile, the fantasy world continues without them. Kingdoms have their own affairs, merchants travel between settlements, adventurers explore dangerous territories, and monsters roam the wilderness. The survivors are unknown outsiders in a world that has never heard of Earth.
For now, the beach is their first gathering point. Wreckage is being inspected, supplies are being sorted, injuries are being treated, and the strange environment is being observed. Strange creatures continue moving through the island.
There is no obvious way home. Nobody knows what caused the storm, why the cruise was brought here, or what waits beyond the island.
Their journey begins. It starts now!
