Other character who appear often in the books are:

Havelock Ventari, CMOT Dibbler, Cohen The Barbarian, Twoflower

Havelock Ventari (The Patrician)

Lord Havelock Vetinari, also known as the Patrician is the almost benevolent ruler of Ankh-Morpork. The Patrician is something of an unknown quantity. People believe such that at some stage he must have been an Assassin and quite good at it. People would also be forgiven for think that Vetinari is as mad as some of his predecessors, ruling Ankh-Morpork will do that to you but this is not the case. Vetinari's mind is like a steel trap which is cleaned, polished and oiled every day and is in perfect working order.

Cut-Me-Own-Throat Dibbler

Dibbler is a man who could sell ice to the Ice Giants at the Hub. He owns his own "Sausage-Inna-Bun" cart, primarily located in Sator Square in Ankh-Morpork. However wherever there is a crowd craving food or any form of merchandise (anywhere on the Disc.), there you will find a Dibbler. Disembowel-Myself-Honorably Dibbler (in Hung-Hung), Cut-Me-Own-Hand-Off Dyblah (Omnia), Fair Go Dibbler (in XXXX) and of course Cut-Me-Own-Throat Dibbler in Ankh-Morpork.

Cohen The Barbarian

Cohen is all a barbarian ever was apart from the fact that he's 70 years old and still going. The reason of this being, all he's done in life is be a barbarian and has never failed cause failure meant death, so he's become an expert at not dying during battles.

Twoflower

Twoflower is considered the Disc's first tourist, travelling from Hung-Hung to Ankh-Morpork to do some site seeing. He bought with him an iconograph maker, lots of gold coins (not gold plated or part gold, pure gold.) and... The Luggage who then became the homicidal travel accessory to Rincewind the 'Wizzard'.
