Blood Omen epigraph

"There is a Magical operation of maximum importance; the Initiation of a New Aeon. When it becomes necessary to utter a Word, the whole Planet must be bathed in blood..."

- Umah

The 'Blood Omen' was an apparent prophecy delivered at the onset of Blood Omen: Legacy of Kain that seemed to foretell the upheavals of the Blood Omen and Blood Omen 2 eras. The passage is also significant for it's real world origin, which is explicitly acknowledged when the prophecy returns in the Legacy of Kain: Defiance comic. The lines of the prophecy are spoken by Neil Ross, but it is unclear who the speaker is intended to be.
