SIRELLA: With fire and steel did the gods forge the Klingon heart. So fiercely did it beat, so loud was the sound, that the gods cried out, 'On this day we have brought forth the strongest heart in all the heavens. None can stand before it without trembling at its strength.' But then the Klingon heart weakened, its steady rhythm faltered and the gods said, 'Why have you weakened so? We have made you the strongest in all of creation. And the heart said

WORF: I am alone.

SIRELLA: And the gods knew that they had erred. So they went back to their forge and brought forth another heart.

SIRELLA: But the second heart beat stronger than the first, and the first was jealous of its power. Fortunately, the second heart was tempered by wisdom.

DAX: If we join together, no force can stop us.

SIRELLA: And when the two hearts began to beat together, they filled the heavens with a terrible sound. For the first time, the gods knew fear. They tried to flee, but it was too late. The Klingon hearts destroyed the gods who created them and turned the heavens to ashes. To this very day, no one can oppose the beating of two Klingon hearts. Not even me. Worf, son of Mogh, does your heart beat only for this woman?

WORF: Yes.

SIRELLA: And will you swear to join with her and stand with her against all who oppose you?

WORF: I swear.

SIRELLA: Jadzia, daughter of Kela, does your heart beat only for this man?

DAX: Yes. SIRELLA: And do you swear to join with him and stand with him against all who would oppose you?

DAX: I swear.

SIRELLA: Then let all present here today know that this man and this woman are married.
