Harbinger of Impending Doom

""And when he had opened the fourth seal, I heard the voice of the fourth beast say, Come and see. And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him.""

- Revelation 6:7-8

There's a group of people held up in a building or house somewhere partying, shopping, or just minding their own business, when all of a sudden, there's some random injured and bloody guy/girl who shows up giving an ominous message that someone/something's trying to kill them, and that it's following them. Sometimes the bloody stranger dies before they can be specific about the threat. Thus the group of friends/family starts to argue and debate among themselves about what he or she could have been running from. And of course, the threat eventually shows up...

Can also involve when said threat doesn't even leave time for the heroes to debate what they are up against and attacks immediately resulting in a Surprisingly-Sudden Death.

A side note for authors to avoid a Rouge Angles of Satin situation, there are only two "r"s in harbinger. "Harbringer" is not a word.

Subtrope of Herald. Compare Vagueness Is Coming.
