Star Trek: Deep Space Nine

The Reckoning (6x21)

:

Stardate: Unknown A mysterious tablet is found in the ruins of B'hala, foretelling that "The Reckoning" will soon begin. As Sisko tries to translate the texts on the tablet, Kai Winn pays a visit to Deep Space Nine, demanding that the tablet should be given back to Bajor. Sisko, getting an impulse from the Prophets, smashes the tablet, releasing strange energy-beings. Subsequentely, a Prophet saying that she must defeat the 'Evil One,' which will then usher in Bajor's Golden Age, possesses Kira. Sisko does not intervene, even when the 'Evil One' inhabits the body of his son, Jake.
