High Quality Content by WIKIPEDIA articles! A huge ship appears in the sky of a distant, alien colony and fires a massive beam, transforming the bustling city below to mountains and fields. As the wave encompasses the planet, the ship's crew comment on the colony's erasure before targeting the species' homeworld. On board Voyager, Captain Janeway is informed by Seven of Nine that the area of space they are currently in belongs to a species that the Borg know as the Zahl. Upon entering this space, though, a small vessel appears off of Voyager's port bow and begins an unprovoked attack. The ship is a Krenim destroyer, and the captain of the vessel (unnamed) barks an ultimatum at Janeway that Voyager must leave "Krenim" space or be destroyed. As the ship's weapons prove useless against Voyager's hull, Janeway ignores the ship and proceeds to negotiate with the Zahl, who disdainfully threaten the weaker Kremin vessel. During their discussion, Tuvok receives ship readings that a temporal disruption involving the homeworld of the Zahl race has just occurred. As they stand there trying to understand what has happened, a wave of temporal energy reaches their sector of space.
