Stavromula Beta was a bar on Earth. It was run by one of Agrajag's reincarnations, Stavro Mueller, and Arthur Dent discovered its name after visiting Agrajag's Cathedral of Hate. After escaping, Arthur mistakenly thought Stavromula Beta was a planet, and asked everyone about it, but no-one knew about it of course. In the last chapter of the book Mostly Harmless, Random Dent, after demanding to get into a bar, meets her mother Trillian Astra there and is about to lower her gun, when suddenly a door bursts open and Stavro Muller comes out of there. Random is startled by this sudden movement, and fires her gun at Arthur. Arthur ducks, and the shot hits Stavro/Agrajag, who screams "YOU!", and collapses. Arthur wonders what to do, but Ford Prefect gives him a matchbox where he reads the name of the bar. Arthur knows, that because he has now been to Stavromula Beta, he can finally die. A great feeling of peace comes over him, and it is finally over, he thinks.
