tanaquil:

“The one with the power to vanquish the Dark Lord approaches … born to those who have thrice defied him, born as the seventh month dies … and the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not … and either must die at the hand of the other for neither can live while the other survives … the one with the power to vanquish the Dark Lord will be born as the seventh month dies …”
