Since the start of the Grand Magic Games in Fairy Tail, the story constantly tries to foreshadow some terrible, apocalyptic event that would happen the day after the Games end.In Endride, Eljuia is pretty upfront that he doesn't have much to go on in his visions of what's about to come, but it always looks ominous.Nowadays it's essentially an open secret. Despite how ubiquitous it is now, at the time all that was known was that a prophecy existed of a Super Saiyan who would be a bloodthirsty apex of the Saiyan Race, and very little was known about it. In a sense, the Super Saiyan prophecy is this in the Namek arc of Dragon Ball Z.The Millenium Falcon arc eventually reveals that the Hawk of Darkness is none other than Griffith, and the age of darkness and chaos has him open the paths and merge the astral and physical realm together, resulting in all sorts of mythical creatures to appear and basically create Hell on Earth, with reality-bending inwards upon itself. It's unclear what is meant, though the first part refers to The Eclipse with the sun dying for a fifth time being the creation of the fifth Godhand and the red lake being the copious amounts of blood from the Band of the Hawk sacrifices.

The Holy See has a prophecy about the sun dying for the fifth time and appearing above a red lake, signifying the appearance of the Hawk of Darkness that will bring about an age of darkness and chaos.All of the times that Nosferatu Zodd popped in to remind Guts and the Band of the Hawk about his prophecy was doom on a layaway plan.Though he does not give any more detail about what the Eclipse actually does or signifies, he doesn't hesitate to tell Guts that when it does go down, horrible things will happen, saying that a storm of death will come and consume the Band of the Hawk which is quite literal when the Eclipse actually does happen - and the chapter where it all starts going down is even called "Storm of Death." A year later, when Griffith reaches his Despair Event Horizon and activates his Crimson Behelit and the Eclipse finally happens, all Guts could think was that he and his comrades were in terrible danger. The Skull Knight makes his first appearance after Guts defeats Griffith and leaves the Band of the Hawk and tells Guts that from that moment up until the Eclipse in one year, he and his friends have begun walking toward their doom.It turns out what they refer to in The Reveal is the Kingdom of Marley who are among living proof that humanity is thriving outside the walls and they plan to conquer for their resources along with the Coordinate. In Attack on Titan, Reiner and Bertolt after revealing themselves make vague references to a force that lies beyond the walls also "their hometown", and repeatedly state that "there's no future inside the walls".

Not to be confused with Harbinger of Impending Doom.

Poor Communication Kills goes with the territory if the confused characters aren't asking the obvious questions or for clarification. A Storm Is Coming is a specific subtrope. See also Cryptic Conversation and The Omniscient Council of Vagueness. Conversely, if the threat (or the character's reactions to it) uproots the existing status quo, see Nothing Is the Same Anymore. If the actual threat fails to impress our frightened heroes, see Feet of Clay. When the threat is never made explicit and only the effects are shown, see Take Our Word for It. Omens, like strange animals, strange behavior or peculiar weather can also work. The audience is reminded of a coming villain or threat but is never really given a clue what it might be.

They typically consist of " Evil is coming", "The darkness will arrive" or possibly " The End Is Nigh", or some such. Hence we get crazy visions and nonsense prophecies and bits of shadowy groups talking of vagueness. Not a problem, unless you can't let the heroes, or the audience, know what that threat is specifically. So the plot of your standard adventure story needs to keep referencing the story arc or continuing plot, and the heroes need to know there's some sort of threat and it's big and dangerous and evil.
