The Dark Messiah was a being who, according to Dark Scripture, was to bring the Scripture to fruition.

In 2373, Damian foretold of the coming of the Dark Prophet and Dark Messiah. (Star Trek: The Cantabrian Expeditions: "Dark Angel")

This scripture follows the same pattern as the Bible in the coming of Jesus Christ: Gabriel, the archangel, coming to Mary, the mother of Jesus; John the Baptist as the prophet; and Jesus as the Messiah.
