History and specifics[edit | edit source]
In 2267, the USS Enterprise was passing near Vartax. The Zond made first contact and through deceit managed to maroon the starship's crew on Vartax. But Spock had remained hidden aboard the ship, and he was able to overcome the Zond leader. The Zond refugees were sent back to Vartax aboard a space bug until Starfleet reinforcements could arrive, but the Zond preferred to self destruct the shuttle and commit suicide rather than return in defeat.
