Spooner Boggis
An unfortunate who came up for judgement for an unknown crime by the then Patrician Lord Snapcase, and was forced to eat his own nose. The name Boggis suggests an association with the Thieves' Guild, but unluckily for Spooner, it had not at this point been formally recognised as a legitimate City guild.
The rebellion that then arose against Lord Snapcase (and, as punishment, hung him up by his figgin) was, at least in the history books, blamed on this incident. But everybody knows that in fact, the real reason a rebellion arose was just because people were fed up with Snapcase's insanity and years of inventive nastiness had built up until their grievances were too much to bear.
