All the places and dragoons belong to Sony.
This happens 800 years after the Moon Crisis

I am the Divine Dragoon, Josh. The dragoons are needed once more. It is my duty to unite the other seven dragoons and fight this powerful, new evil. I must first go to Serdio to find the Jade Dragoon. I just hope the Serdian Royal Family still has the Dragoon Spirit. I remember my father telling me about the Moon Crisis that happened hundreds of years ago. There were seven dragoons and my ancestor, Dart, was the Red-Eyed Dragoon and the Divine Dragoon. This
story has been passed down for many generations. The king of Serdio was supposed to be the Jade Dragoon. The quickest way to Serdio is the Limestone Cave. I hope it hasn't collapsed after 800 years. I set out for the prairie north of Seles, my hometown. As I walk, I remember that Dart walked here centuries before. It will take me a couple of days to reach the Limestone Cave. There aren't any new monsters, which is surprising. It's always a mole or a vampire kiwi. The first night and day pass uneventfully, as well as the second day. But during the second night, things begin to get strange. I hear sounds I've never heard before, and I feel like I am being watched. I sense a dark energy outside the circle of light the fire casts and quickly change to a dragoon. After I change, the energy seems to get stronger, as if challenging me.

I yell, "Show yourself, whatever you are!", but nothing happens. Then I hear a voice in my head that sounds as if it were the root of evil itself.

"You dare try to unite the dragoons right under my nose. It's hopeless, boy. No matter how you try, you will never beat my master. Observe how weak you are."
I am suddenly knocked on my back with tremendous force, and the voice laughs.

"HAHAHA!! That was only a fraction of my power, which is only a fraction
of my master's power! Give up now, while you still have a life! Accept that my master cannot be beat, for your death would be a wasted death if you tried to beat him. HAHAHA!!"
The voice disappears from my mind and I to figure out who, or what, that thing was. I do not sleep that night, but continue on my journey to Serdio. I think, "I hope that thing hasn't reached Serdio yet." I reach the Limestone Cave in the morning and am thankful it hasn't collapsed. The river inside is still flowing and the Rock Fireflies are also still there.

"Not much has changed, I guess," I think. The cave never got a new guardian after Dart and his friends killed Urobolus, so the passing should be easy. There's nothing more in the cave, so I leave. As I exit, I see Indels Castle in the distance and hope that the king will help me.
