Narimba
Narimba is a planet invented by Bob. It is a gas planet and it's dominant color is dark green. It is also very small, although Bob failed to specify the exact radius. He also omitted the approximate radius. In fact, it is highly unlikely Bob even knows what a “radius” is.
According to Bob, nobody lives on this planet. According to philosopher Dan Dindridge, nobody wants to anyway.
Bob's friend Tom disagrees. He claims that there is a special institution called The Narimba Foreigners Office, which processes people's requests to immigrate to Narimba, as well as buy land and containers of Narimbian gas. The composition of the latter is disputed, and the debate has resulted in a number of slightly drunken brawls between Bob and Tom. So far, the score is 2:1 in Bob's favor.
Their common friend, Naomi, produced a lengthy white paper on the subject of how a more scientific approach could be used to define gas composition of fabricated planets in general. Between 2013 and 2017 she authored a book on the Narimbian gas specifically, but never published it, because she was writing it in her mind while falling asleep, so it never actually ended on paper. The book remains unwritten.
The destruction controversy
According to Bob, the original inventor of Narimba, the planet no longer exists. He claims that it was devoured by a TSF about a century ago. Bob's friend Tom vehemently disagrees, citing creative differences and Bob's lack of responsibility towards his created worlds.
In order to fix the injustice, Tom has imagined a universe alternative to Bob's in which the planet survives.
