No Time Like the Present

At the edge of the finalfrontier.

Summary
Cardassian agents covertly return to Bajor to retreive an ancient artifact hidden when the occupation came to an end. When touched, the artifact emits waves of temporal distortion, creating disturbances across the Federation and alerting the artifact's creators, an ancient race eager to reclaim what was once their most feared weapon.
