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 a star "like a boiled egg". The Doctor teamed up with a lone Dalek to locate the Orb that served as a key to locating the Starbane. (GAME: The Doctor and the Dalek)
