Rincewind
Rincewind is a wizard. Probably the most talentless the Disc has ever seen... In fact, he isn't really a wizard since he was fired from the Unseen University when he was a student: he tried to read a book known as the Octavo. The problem with this book is that it holds The Great Eight spells, and one of them jumped into Rincewind's mind, refusing to let him remember any other spells (which is quite annoying when you plan to be a wizard). For a living, Rincewind uses his innate gift for languages (that's why he became Twoflower's guide). Unfortunately, Rincewind seems to find disaster at every turn, despite his cowardice. Eventually, he is gifted with a razor-sharp instinct for survival which allows him to still be alive although he met Death numerous times, therefore, he is getting to know Him quite well. Few people can be proud of it since they generaly only meet Him once.
Twoflower
Twoflower is a tourist. The first (and probably only) one on the Disc. He comes from the Agatean Empire and seems unaware of danger. Instead, he considers it with fascination. Twoflower believes there is no point in worrying about things he cannot change and that everything will work out fine in the end. Miraculously, it usually does. Twoflower is the owner of the Luggage and carries his iconograph everywhere he goes (a little black box with a round glass eye protruding from the center of one face, which contains a little demon that draws pictures very quickly), looking for that next exciting photo.
Luggage
The Luggage is basically a chest. It's particularity comes from the fact it was built with Magical Sapient Firewood. This seems to make the Luggage virtually undestructible, loyal, faithful, and... homicidal to anyone who is a threat to its owner, who happens to be Twoflower. It has hundreds of little legs and a nasty habit of eating anyone who gets to close (nobody knows what happened to them in it). Mysteriously, it seems to always be full of Twoflower's clean laundry. The Luggage is without doubt the ultimate travel accessory.
Death
There are many Deaths, since there is so much work for them to do. The Death of the Discworld is a traditionalist, which is appropriate for an anthropomorphic personification whose shop floor is a flat world carried on the back of an enormous turtle. He wears a black robe, carries a scythe, rides a white horse and TALKS IN A HEAVY VOICE and owes his existence in this incarnation to humanity's ancient tendency to put faces to names. Death is possibly one of the most misunderstood characters on the Disc. It's not Death's fault that people die, it's just that He happens to be there when it happens (in fact, He often delegates the task to a subordinate, such as Disease or Famine, except for wizards who have the privilege that Death always comes personally when they die). Death is seven feet tall, thin, and despite being a skeleton, manages to demonstrate emotions such as shrugging and smiling. Death does not understand why humans, whose lives are shorter than the tiniest heartbeat of the universe, waste so much time and make their lives as complicated as possible. Death is strictly speaking the death of everything, including things that spend their whole short life growing on damp bread, but Death allowed the Death of Rats an independent existence, maybe because he has acquired a sense of humour and a natural cynicism that are quite alien to Death himself. Death's catch phrase is "THERES NO JUSTICE. THERE'S JUST ME".
Hrun
Hrun is a legendary barbarian. He is practically an academic by Hub standards, in that he can think without moving his lips. He is delighted to escort Rincewind and Twoflower after seeing his large bag of gold coins. Hrun is the owner of Kring, a talking sword. A talking sword may seem odd, but everything seems to talk on the Disc. Rocks, trees, bushes, you name them and they talk. He has led his life like most barbarians, which means slaying dragons, rescuing damsels in distress, and searching for riches.
Cohen
Cohen the barbarian is the Disc's most famous hero. Cohen is now very old and has lost one eye and all his teeth. This makes him speak in quite a funny way. However, it would be a big mistake to be fooled by his age. Of course, in such a dangerous job as barbarian, you don't get as old as Cohen without being very good at what you do.
Mort
Mort was the last boy looking for someone who would apprentice him on Hogswatch Night. Death took carre of it. He could not have imagined what trade he would end up taking. However, after learning that being dead was not an obligation, he decided to accept. Mort is tall and awkward and described as being made of elbows, knees and toes. Mort recently discovered that romance does not match very well with his work.
Cutwell
Cutwell, a wizard, has his own magical shop. He is a very untidy man, leaving food debris all over the place. Cutwell was hired by Princess Keli as the Royal Recognizer. This means that it was Cutwell's job to remind everyone that Keli was still alive. He was also hired by Mort to discover why he could walk through walls. Cutwell enjoys the frequent cigar, but struggles with the celibate side of being a wizard.
Eskarina
Eskarina ("Esk") is the first female wizard on the Disc. She was given the wizard's staff at birth by Drum Billet when mistaken as the eighth son of an eighth son, when in fact she was the eighth daughter of an eighth son. Eskarina is an inquisitive and polite little girl who has a thing for giving people long, squinty-eyed stares.
Granny Weatherwax
Esmerelda 'Granny' Weatherwax is the self proclaimed Disc's greatest witch. She comes from a small town in the Ramtops known bizarrely as Bad Ass. However, rather than using spells to achieve goals, she prefers to use trickery and persuasion or, as she calls it, Headology. She's also a dab hand at mixing herbs and looking after goats. Contrary to what people might think, Granny Weatherwax hates brooms, and prefers walking to flying.
