How about an adventure in space? A crew of astronauts on a mission to a distant planet. Their ship malfunctions, and they are forced to land on an unknown planet. There, they discover strange alien life forms and must figure out how to repair their ship and get back home while surviving in this alien environment.
A treasure hunt adventure is always a good choice. For example, pirates buried a chest full of gold on a deserted island long ago. The story can follow a group of modern-day treasure hunters who find an old map leading to the island. They have to solve riddles and overcome traps set by the pirates to reach the treasure.
You could start with a young protagonist who discovers a mysterious old map in their attic. This map leads them to a hidden portal in an ancient forest. Once through the portal, they enter a world filled with talking animals and floating islands. There, they must find a magical crystal to save this new world from an evil sorcerer who is draining its magic.
One idea is to set the adventure in an uncharted jungle. The main character could be a young explorer who stumbles upon a lost civilization. There could be dangerous animals like giant snakes and wild cats. Mysterious ruins and hidden treasures would add more excitement. Another idea is a sea adventure. A sailor gets caught in a storm and washes ashore on a strange island filled with mythical creatures.
Another idea is to set the story in a small village that is haunted by a strange curse. A brave storyteller arrives in the village and decides to investigate. They find out that the curse was placed by an angry wizard long ago. The storyteller embarks on a journey to find the wizard's lair and convince him to lift the curse. On their journey, they meet various characters who have been affected by the curse and their stories add depth to the narrative.
The story could begin with a prophecy about a lost city that holds the key to saving the world from an impending doom. A group of adventurers from different backgrounds - a thief, a healer, and a warrior - come together to search for this lost city. They journey through a dark forest filled with enchanted trees that try to mislead them, and then cross a wide river with powerful currents and dangerous water monsters.
One quick thing to start a story is to think of an interesting character. For example, a mysterious old man with a long white beard who lives in a lighthouse. Then, consider a problem or conflict for this character, like he has lost his memory and is trying to remember his past. Another idea is to begin with a vivid setting. A dark and spooky forest filled with strange noises can be a great start. You can also start with an exciting event, such as a sudden explosion in a small town that gets everyone's attention.
One idea could be to create a world with different magical realms. For example, a realm of fire where the inhabitants can control flames, and a realm of water with mermaid - like creatures. The main character could be a young adventurer from a normal world who accidentally discovers a portal to these realms. Their goal could be to find a powerful artifact that can restore balance between the realms as they are on the verge of war.
You could use the idea of a hidden object from the list. For example, a long - lost family heirloom that holds the key to a mystery. Maybe it has some strange markings that lead the protagonist on a journey to uncover its secrets.
A group of friends stumbles upon a magic map while on a camping trip. The map shows the location of a long - lost magical artifact. They embark on a journey through different terrains like mountains and swamps, facing various magical creatures along the way. Their friendship is tested as they face challenges and temptations in this adventure.
A mysterious encounter can be a good topic. Picture a person walking in a forest at night and coming across a strange, glowing figure. Is it a fairy? An alien? Or just a trick of the light? The main character could then be driven by curiosity to follow it and get into all sorts of adventures and danger.
You can write about personal experiences, like a memorable trip or a first encounter with something strange. For example, writing about the time you got lost in a new city and the interesting people you met during that adventure.
