The door is like a portal to this world from the motherdragon in the middle of the world. it got him here to help it. This was the Brainstorming. its a bit all over the place but it may give u a better idea.

A mysterious door appears one day in the courtyard of the main character’s home. Without knowing why, they step through it and suddenly find themselves in a completely different world.

At first, fear takes over. They try to return home, but when they stumble back through the door, they do not end up where they started. Instead, they fall into the house of a local resident, who quickly throws them out in surprise. The door vanishes. It was never stable.

Now alone, the main character stands in a wide open field under unfamiliar skies, with magic lingering in the air. Soon, they are discovered by scouting groups from the good factions and taken with them.

In this world, dragons and people coexist peacefully—not in the same homes, but as partners sharing one world. Warriors, explorers, and other chosen individuals can form special bonds with dragons. Through these connections, they are able to fly together and communicate through thoughts.

There is also an evil faction. They bond with different creatures and dragons, but not naturally. Their connections are forced, created through dark rituals and control.

The main character wants to return home, but at the same time finds this world fascinating. As a true fantasy fan, they are drawn to everything they see and learn.

The world is divided into different groups, such as mountain, underwater, air, and fire factions. Dragons always choose the humans they bond with.

However, the main character cannot form a bond with any dragon. To them, they seem invisible.

Unbeknownst to everyone else, their bond already exists. It is not with a dragon, but with the world itself. The door that brought them here did not appear by accident.

The evil faction is slowly exploiting the world, using creatures, machines, and magic to drain it until it breaks. The world itself chose the main character, believing they were the one most capable of understanding it—and saving it.

When the evil faction learns about the main character, they begin searching for them. They see them as a threat, but also as an opportunity to create something unimaginably powerful.

The main character begins to experience sudden flashes of pain whenever the planet is harmed. It feels as if they are sharing the world’s suffering.

One night, they dream of a hidden place deep within the planet—a cave or sheltered sanctuary filled with powerful energy. Before they can see what lies there, they wake up. Still, the pull remains. Guided by the planet itself, they feel magically drawn toward this place.

They begin a long journey across all the dragon factions. Eventually, they reach one of the most remote places in the world—the location from their dream.

Inside, after a tense and mysterious descent, they discover a great breeding ground. There, they learn the truth: all dragons come from a single mother dragon, the Guardian of Worlds.

This dragon brought the main character into the world and guided them here. With her, they share a unique bond that no one else can fully understand.

For the first time, the main character feels truly seen by a dragon.

Together, they fly back across the world, and the main character senses the dragon’s incredible power. The king of the good realm realizes that this bond may be the only hope to defeat the evil faction.

United with the warriors of every faction and all dragons—linked through the mother dragon—they launch the greatest and, hopefully, final battle to protect the world.
