The Family of Death.
•DEATH: An anthropomorphic personification of death. He is a 7-foot-tall skeleton of polished bone, in whose eye sockets there are tiny points of light (usually blue). He normally wears a robe apparently woven of absolute darkness. Death's scythe looks normal enough, except for the blade, which is so thin you can see through it - a pale blue shimmer that could slice and chop sound. His sword has the same ice-blue, shadow-thin blade, of the extreme thinness necessary to separate body from soul. His face, of necessity, is frozen into a calcareous grin. His voice is felt rather than heard. His voice is heard in capital letters, like this: HELLO. Death has a family…or as much of a family as the anthropomorphic personification of death can have. Death also likes cats.
•Mort: is a Deaths apprentice, the father of Susan, the Dutch of Sto Helit, and the husband to Ysabell. He first appears in the eponymous novel Mort, where Death chooses him as his apprentice. Mort's original name is Mortimer.
Ysabell is the adopted daughter of Death, who saved her as a baby when her parents were killed in the Great Nef desert (no explanation has been given as to why he did this). When first encountered in the Discworld books, she is a sixteen-year-old girl with silver hair and silver eyes who, it transpires, has been sixteen for around thirty five years (no time passes in Deaths Domain). She also has a fixation for the color pink.
Susan: Susan is Deaths grandchild. Daughter of Mort (Deaths former apprentice) and Ysabell (Deaths adopted daughter) , granddaughter of Death Himself, Susan is frequently subjected to visits from Quoth the raven and the Death of Rats. Her consternation with her heritage is an ongoing issue. Susan usually wears black and is quite in favor of sensible things.
