Dark Prophecies are rare and not well understood.

TGH,Ch7#

The Myrddraal writes the Dark Prophecy on the wall of the prison in the Fal Dara keep when Padan Fain is freed. It is not certain if it is truly prophetic or if it is merely evil ramblings. Most of the interpretation is clear.

Daughter of the Night,[1] she walks again.
The ancient war, she yet fights.
Her new lover[2] she seeks, who shall serve her and die, yet serve still.
Who shall stand against her coming?
The Shining Walls[3] shall kneel.
Blood feeds blood.
Blood calls blood.
Blood is, and blood was, and blood shall ever be.

The man who channels[2] stands alone.
He gives his friends for sacrifice.
Two roads before him, one to death beyond dying, one to life eternal.
Which will he choose? Which will he choose?
What hand shelters? What hand slays?
(refrain)

Luc came to the Mountains of Dhoom.
Isam waited in the high passes.
The hunt is now begun. The Shadow's hounds now course, and kill.
One did live, and one did die, but both are.[4]
The Time of Change[5] has come.
(refrain)

The Watchers wait on Toman's Head.
The seed of the Hammer[6] burns the ancient tree.[7]
Death shall sow, and summer burn, before the Great Lord comes.
Death shall reap, and bodies fail, before the Great Lord comes.
Again the seed slays ancient wrong, before the Great Lord comes.
Now the Great Lord comes.
(refrain)

ToM,Epilogue#

This is the passage from the book of Dark Prophecy that Moridin shows to Graendal.

"Lo, it shall come upon the world that the prison of the Greatest One
shall grow weak, like the limbs of those who crafted it. Once again, His
glorious cloak shall smother the Pattern of all things, and the Great
Lord shall stretch forth His hand to claim what is His. The rebellious
nations shall be laid barren, their children caused to weep. There shall
be none but Him, and those who have turned their eyes to His majesty.

In that day, when the One-Eyed Fool travels the halls of mourning,[8] and
the First Among Vermin[9] lifts his hand to bring freedom to Him who
will Destroy, the last days of the Fallen Blacksmith's pride shall come.
Yea, and the Broken Wolf, the one whom Death has known, shall fall and
be consumed by the Midnight Towers.[10] And his destruction shall bring
fear and sorrow to the hearts of men, and shall shake their very will itself.

And then shall the Lord of the Evening come. And He shall take our
eyes, for our souls shall bow before Him, and he shall take our skin, for
our flesh shall serve Him, and He shall take our lips, for only Him will
we praise. And the Lord of the Evening shall face the Broken Champion,[11]
and shall spill his blood and bring us the Darkness so beautiful. Let the
screams begin, O followers of the Shadow. Beg for your destruction!
