You are one of a group of incredibly rare individuals. You are a Walker able to to jump between realms. You will start the game after just becoming aware of your abilities after unwillingly being transported to a small pocket realm where you find several others as surprised as you are. You have only whatever you were carrying when your transportation occurred.
This game is loosely inspired by things such as Magic the gathering and the Pendragon Adventure Book series. Your characters will end up traveling across realms and while there will be an overarching threat there will be significant freedom to pursue your own ends and try and find other plot hooks
