Romulan Star goes Supernova

A star in the Romulan Empire goes Supernova. Ambassador Spock attempts to counter the resulting shockwave using Red Matter, but is unable to save the planet Romulus from destruction. Spock and the Romulan mining ship Narada, commanded by Nero, are dragged into a black hole created by the Red Matter detonation and arrive in the past. Nero's arrival in 2233 and subsequent attack on the USS Kelvin creates the Kelvin Timeline.
