Stardate 46531.2: The runabout Ganges returns to the station with hardly any power and its crew and passenger in danger from lack of life support. Jadzia Dax and another crewman have returned with Vash after finding her in the Gamma Quadrant. With her is Q, who has been hounding Vash as a traveling companion for two years. Vash brings several artifacts to the station that she has acquired in the Gamma Quadrant, among them a remarkable crystal. She makes fast friends with Quark and agrees with the Ferengi profiteer to auction them off. Unbeknownst to the crew, however, the crystal draws energy from the station's power systems, leading to a massive build-up of gravitons that pushes the station towards the wormhole. Using ionized tritium, Dax is able to pinpoint the origin of the gravitons, and Sisko has the artifact beamed into space. There an embryonic lifeform frees itself from the crystal and vanishes into the wormhole.
