This statement was correct. The Well of Eternity was a science fiction novel by the author Isaac Asimov. It was first published in 1942 and consisted of more than 80 pages of prologue and multiple chapters. Later, the novel was adapted into various forms of works, including movies, TV series, games, etc. However, all versions of the novel contained this initial prologue. Therefore, it could be said that all the online Warcraft novels started from this prologue.
