The people that exist within the Never-ending Story are also known as Characters. The Never-ending Story, and all its iterations, exist within the Story Realm. There are different kinds of Characters of the NeS and can be categorised - categories often referred to in the NeS itself by those Characters. One of the most important is the Main Character of the story, a mantle held by Gebohq Simon for the original Never-ending Story and then Losien Simon for half of the Never-ending Story2. Characters are created by the Writers. These Writers will often have an 'avatar character' that represents themselves, in at least name, within the Story itself.
Writers often choose a Character somehow based upon themselves, at least in name only, and almost always as their first character. Rob X the Writer has Rob X, Gebohq the Writer has Gebohq Simon, Ares the Writer has Ares, etc[NeS1 1].
Minor Characters are usually background Characters or Characters that were featured for a very short period, usually because their Writer didn't stick around. There are many examples of Minor Characters, such as Space Orca[NeS1 2].
