A Domino Revelation occurs when the revelation of a previously hidden truth leads to another revelation, then another, like the knocking over of dominoes.

Often evoked in {{fantasy}} works, where the revelation that one mythological or legendary species exists leads to finding out that many more also do, and works featuring conspiracy theories, where finding the shadowy figures behind a seemingly minor crime opens up a vista of sinister plots all emanating from the same source. In {{romance}}, one confession can often lead the way to one or several more.

It gets a good bit of use in UrbanFantasy and SteamPunk works as well.

AllMythsAreTrue is a common end result when all dominoes have fallen. May overlap with TheMasquerade or TheConspiracy where the protagonist is introduced to their secrets.

[[folder:Anime and Manga]]
* ''Anime/PuellaMagiMadokaMagica'' does this with {{Awful Truth}}s. In the wake of [[spoiler:Mami's death]], Kyouko's appearance shows that few magical girls are as altruistic as [[spoiler:Mami]] was. This leads to Sayaka's confrontation with Kyouko on the bridge, where it's revealed that [[spoiler:Soul Gems literally [[OurLichesAreDifferent contain the soul of a magical girl]]]]. This, in turn, leads Sayaka to [[spoiler:fall into despair, corrupting her Soul Gem and revealing that a corrupted Soul Gem doesn't break or disappear, but instead turns into a Grief Seed]], a revelation which prompts Kyubey to explain to Madoka [[spoiler:the true nature of the magical girl system]]. Additionally, the process of [[spoiler:Sayaka falling into despair]] leads to a chain of events resulting in the revelation that [[spoiler:Homura has some form of time travel/timeline changing ability]]. Basically, the revelations show piece-by-piece how the inner workings of the fairly cliche-looking premise are actually [[DarkerAndEdgier terrible, terrible things]].
