In 2387, a major cataclysm of galactic proportion was averted when Ambassador Spock of Vulcan caused the Hobus supernova to be absorbed into an artificially created black hole. As a result of the supernova, however, the planet Romulus was destroyed and Nero sought to avenge the loss of his world. Both he and Spock were thrown back in time to the 23rd century. Nero then spent the next twenty-five years planning his revenge when Spock arrived in the past. Spock was then forced to bear witness to the destruction of the planet Vulcan in the year 2258. With ten thousand of his brethren left, Spock sought to preserve what was left his people while advising his past self in an alternate timeline to remain in Starfleet.
