Since the first novel, The Colour of Magic (1983), the series has expanded, spawning several related books and maps, five short stories, cartoon and theatre adaptations and even music inspired by the series. The first live action screen adaptation for television (Hogfather) was broadcast over Christmas 2006. Another one for the cinema (The Wee Free Men) is currently in development.
Gytha Ogg (usually called Nanny Ogg) is a witch and member of the Lancre coven. The character of Nanny Ogg is based on the Mother stereotype of the Triple Goddess myth, and probably influenced by the character Nannie Slag in the Gormenghast series. She's had 5 husbands and been married to three of them and has fifteen children who survived their early childhood (one was born some ten years after the death of her last husband). She has as well innumerable grandchildren and great-grandchildren, but that's incidental; what makes her the Mother is her mentality. People go to Granny Weatherwax for help when they have no choice, but they go to Nanny for advice all the time. Granny is respected, but Nanny is actually liked.
Nanny Ogg has a talent for getting along with people and fitting in. As described in Maskerade, people, after knowing her for fifteen minutes, feel like they have known her all of their lives. Granny Weatherwax knows about this ability, and recognizes its use, and wonders sometimes if it would have been worth acquiring it. Nanny is a lot wiser than Esme (Weatherwax) in some ways, and certainly wise enough not to show it. Gytha Ogg is seen as "one of the people" in a way that Esme isn't. While Granny thinks there's no point in competing if you aren't going to win, Nanny reckons the sympathy you get for being a good runner-up is much better. Granny comes across as judgemental, whereas Nanny has a mind so broad she could tie it under her chin. She appears to be kinder than Granny, but is equally prepared to make tough decisions if necessary.
Lancre (pronounced Lanker) is a fictional country from the Discworld series. It is situated in the Ramtop mountains, about 500 miles Hubwards of the city of Ankh-Morpork. It is the best-known of hundreds of tiny countries in the Ramtops, occupying a vertiginous shelf looking over the Sto Plains.
Lancre is based mainly on the North of England (as in Lanc(ashi)re, with strong resemblance to the windswept, hilly, northern regions (the only piece of flat, level ground in Lancre is in a museum). However, it is reminiscent of many rural areas in Britain and elsewhere. It also contains elements of the Swiss Alps and the Appalachian Mountains. Pratchett has described the tiny country as "solid folklore"; it is the place all the legends of our world's countryside really happened. Ankh-Morpork serves a similar function for urban folklore, but not as blatantly.
Part of the reason for this is that the Ramtops are a major earthing point for the Discworld's magical field. Headless horsemen and walking trees are part of the landscape, as are witches. Lancre is famous for witches, especially since the publication of The Joye of Snackes (an erotic cookbook) by "A Lancre Witch" (Nanny Ogg). Lancre is also the gateway into the "parasite universe" of the elves. The other thing Lancre is famous for is young people going off and seeking their fortunes (usually in Ankh-Morpork).
She'd become a governess. It was one of the few jobs a known lady could do. And she'd taken to it well. She'd sworn that if she did indeed ever find herself dancing on rooftops with chimney sweeps she'd beat herself to death with her own umbrella.

In Ghat they believe in vampire watermelons, although folklore is silent about what they believe about vampire watermelons. Possibly they suck back.

Mort is fourth Discworld novel, and also the name of its main character. Published in 1987, it is the first to focus on the Death of the Discworld, who only appeared as a side character in the previous novels. As a teenager, Mort's personality and temperament made him rather unsuited to the family farming business, resulting in his father taking him to a local hiring fair. Mort is hired by Death as an aprentice. The pressure of the job (and a crush on a princess who is due to die) forces Mort to make a few mistakes, but like all good heroes, he grows some spine, gains some self control, challenges Death to a duel and waltzes away with the girl in the end, but not the correct girl by normal fantasy standards.
