Starbane

The Starbane was a Gallifreyan warship capable of destroying entire galaxies. A huge temporal energy reactor, the space-bound facility could, according to the Twelfth Doctor, split open a star "like a boiled egg".

The Doctor teamed up with a lone Dalek whom he named "Lumpy" to locate the Orb of Fates that served as a key to locating the Starbane. They intended to destroy both the Orb and the Starbane to prevent it from falling into the hands of either the Daleks or the Cybermen. However, when they retrieved the Orb and arrived on the vessel, they found it already under Dalek occupation. The Doctor guided Lumpy through the Starbane and eventually placed the Orb into the reactor, destroying the ship. (GAME: The Doctor and the Dalek)
