The Kessok Incident' occurred in 2376 following the sudden explosion of a star in the Vesuvi system, known as the the Vesuvi Event. It was later determined that the star's destruction was not a natural occurrence, but induced by an unknown weapon. The USS Dauntless was in the Vesuvi system on a routine patrol when the explosion occurred. The resulting shock wave destroyed the shuttlecraft the Dauntless captain was piloting and severely damaged the Dauntless. Once repairs were completed, the Dauntless first officer was promoted to captain and assigned to investigate the unexpected explosion of the Vesuvi star.
