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 can base the long story on a prophecy. There's an ancient prophecy that foretells the rise of a great hero. Set the story in a medieval - like world filled with knights, wizards, and dragons.

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.

A sailor gets caught in a storm and washes ashore on a strange island filled with mythical creatures.
One idea could be a young hero who discovers a hidden map that leads to a magical realm. In this realm, there are all kinds of strange creatures like talking animals and flying plants.

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.
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.
A fantasy adventure could revolve around a cursed sword. A young swordsman comes across this sword in an old, haunted castle.

A simple idea is to write about two friends who grow up in different social classes. One is from a wealthy family and the other from a working - class family.

Their friendship is tested when the wealthy friend's family faces financial problems and the working - class friend has to make sacrifices to help.
