Harmony and Redemption

The Harmony and Redemption was a space cruise ship that catered exclusively to wealthy mass murderers, with suites reserved for planet-burners. Even its staff was required to have a history of indiscriminate killing. Tickets cost a minimum of one billion credits.

During a tour of seven galaxies, the Harmony and Redemption ran into a meteor storm near Gamma Eridani and crashed into Darillium. Four centuries later, River Song dug up the wreckage, guided by History's Finest Exploding Restaurants.

With knowledge of the exact time of the meteor storm, River arranged for her sale of the Halassi Androvar to take place on the Harmony and Redemption just before so that she would have a ready means of escape. After obtaining the Androvar on Mendorax Dellora, she arrived on the starship in the TARDIS with the Twelfth Doctor and Hydroflax. River and the Doctor were the only survivors of the ensuing crash, as they were inside the TARDIS. (TV: The Husbands of River Song)
