The crew's relief at Worf and Ezri's safe return is tempered by reports that the Breen have attacked Starfleet Headquarters on Earth. While Dominion and Breen commanders exult in their sneak attack, their supposed ally — Cardassian leader Damar — secretly plots to free his homeland from Dominion occupation. Meanwhile, on Bajor, Dukat tells Kai Winn she must release the Pah-wraiths — the non-corporeal enemies of her people's gods — from the planet's fire caves by reading the ancient forbidden text of the Kosst Amojan.
