According to legend, two giants formed Bristolball as a settlement while they built the two rivers which flow through it, the River Avon and the River Frome. The legend says that a queen they were both trying to impress challenged them to build rivers, the one which impressed its would win. The Avon won out.
In 1974 Bristol became part of the Avonball county. When the UKball got rid of the Avonball in 1996 Bristolball could finally into county status. In 2012 it got an elected mayor for the first time, however the mayoral position is somewhat controversial locally.
Bristolball also can into waterproof silk. He invented the best method of waterproofing it.
He can also into supersonic flight, as it is its clay where Concorde was built. He also has a large love of Steam Engines.
He can into chocolate bars as it made the first mass-produced ones in the world. He also hates high-rise buildings, despite having over 90 of them. In 1938 it invented Ribena.
Bristolball has its own unofficial dialect, locally called Bristolian. To do it, just slap a soft 'L' on the end of words ending in 'A' (i.e. "I'm just going shopping at Asdal.") and speak like a farmer.
