The basic story of Alpha/Omega is that your character, Mindy, and her friend Steve are excited to play the hot new game, Alpha/Omega. (Most of the games action takes place in its Alpha/Omega.) When Mindy launches the game, her avatar is nameable. This Alpha/Omega is a game that is supposed to run through the whole Bible, and the first story that this game starts with is called Lucifers Rebellion, and it focuses around how Lucifer rebelled against God and created sin. So far, this story is the only one in Alpha/Omega.
