As they travel to their next destination, Slartibartfast explains that he is trying to stop the robots from collecting all the components of the Wikkit Gate. Long ago, the peaceful population of the planet of Krikkit, unaware of the rest of the Universe due to a dust cloud that surrounded its solar system, were surprised to find the wreckage of a spacecraft on their planet. Reverse engineering the vessel, they explored past the dust cloud and saw the rest of the Universe, immediately taking a disliking to it and determining it must go. They built a fleet of ships and robots to attack the rest of the Universe in a brutal onslaught known as the Krikkit Wars, but were eventually defeated. Realizing that the Krikkit population would not be satisfied alongside the existence of the rest of the Universe, it was decided to envelop the system in a Slo-Time envelope, allowing Krikkit to survive long after the rest of the universe has ended; the Wikkit Gate was the key to the envelope. (This also explains why Earth is ignored by the rest of the galaxy; any species that would turn a memory of a horrific war into a sport isn't worth bothering with.) However, one ship carrying a troop of robots from Krikkit avoided the Slo-Time envelope, and these robots began to retrieve the pieces of the Gate after they were dispersed about space and time.
