In times in which Sunlight was a Mystery, and Pokemon is one the brink of Darkness themselves, you must save all of those who dare invade their property, and try finding the reason of the Eclipse. All of those who think that they can take on this challenge, accept three terms for your own survival. 1. Never venture without a Pokemon to protect you. 2. Stay close to those of which are in need, in their time of need. 3. Whatever you do, Don't go into the Darkness.
If you think you can follow these terms, feel free to attempt victory.
I am just going to be a GM that keeps it going, and entertaining, so you will just play for yourselves.
