Stardate 48543.2: The first
joint scientific venture between Bajor and Cardassia
is to be a communications relay satellite placed at
the Gamma Quadrant end of the wormhole, and two
Cardassian scientists - with an observer from the
Obsidian Order not far behind - arrive on DS9 to deliver the payload. As if the
unease about the new Bajoran-Cardassian peace accord
isn't enough, Vedek Yarka arrives from Bajor to
inform Sisko -
still regarded as the Emissary in Bajoran culture -
that prophecy predicts the Cardassians' presence will
result in calamity, not the least of which will be
the closure of the wormhole. As the mission
progresses, it all starts adding up as prophesied,
including the appearance of a comet which could
damage or destroy the wormhole.
