Hello there!
Welcome to the Sinnoh region.
It's a little different from when you last visited this place. Not all of it good.
This place is changed with an imbalance between the legendaries of the region, causing strange phenomenon to appear everywhere. We have since dubbed them "Chaos Events", the events have been observed to to do a variety of things from a foreign item to appear, to large buildings materialising for a period of time. Some reports of Chaos Events even speak of people to travel through time and space and return like nothing even happened.
These foreign items seem to act differently from from what they look like, but that will be saved for another time.
For now, it is almost time for a budding young trainer to begin their journey through these strange times, what will they find? Who will they meet?, What kind of person are they?
Who am I? So many questions, too little time.
Let's go see them now.
