Only one person, who was not a passenger, but who hid himself on the spaceship, has not aged – Zarniwoop. Zaphod subsequently learns that, before he sealed part of his own brain, he was collaborating with Zarniwoop to find out who rules the universe – this being Zarniwoop's obsession. In the books, Zarniwoop is marooned on The Ruler of the Universe's planet by Zaphod et al. and is stuck outside the only shelter for weeks in driving rain, because The Ruler is unsure as to whether Zarniwoop's desperate thumping on the door is real or not. At the end of the second radio series, he is similarly marooned, but this time by Arthur, with Ford Prefect and Zaphod Beeblebrox for company. In the Quintessential Phase radio series, Zarniwoop is revealed to be the same person as character Vann Harl (Zarniwoop is his first name), and a Vogon in disguise. He has escaped being left on the desolate planet and is masterminding the Guide's new all-powerful format. Appears in , , and . On the radio, Zarniwoop Vann Harl is voiced by Jonathan Pryce. His casting was accidental – he had been hired to play a different role (The Ruler of the Universe, whose lines had apparently not been written in time). He was happy to return for the final series, however, when a lot more was revealed about the character, much of it appropriately sinister, Pryce now having become well known for playing villains. Zarquon is a legendary prophet. He is worshipped by a small group visiting The Restaurant at the End of the Universe, and is old, bearded, robed, wreathed in light, has starry eyes and a crown of gold. His name is frequently invoked as a curse, specifically a substitute for "God" or "fuck", such as "Holy Zarquon's singing fish" and "for Zark's sake" in the first meaning, and "you zarking frood" and "zarking fardwarks" (meaning "fucking hell") in the second meaning. It is only on "our" visit to Milliways that Zarquon does indeed appear – his overdue second coming – moments before the Universe ends (His last words are "How are we doing for time?"). The host Max claims that he had done the show "over five hundred times" and "nothing like this had ever happened before".
