Death (Discworld)
Death has appeared in every Discworld novel, with the exception of "The Wee Free Men" and "Snuff", and had a possible cameo at the end of "Johnny and the Dead" (the character was not identified, but spoke in unquoted small caps). The Discworld books with Death as a leading character, starting with "Mort" in 1987, are:
Death (Discworld)
Death resides in an extra-dimensional realm called Death's Domain. Within the domain, his home looks like a Victorian house with a garden and is well tended, but is predominantly in shades of black and decorated with a skull and crossbones motif. It is called "Mon Repos", (Quirmian for "my place of rest"), and is much larger on the inside, because Death has not quite mastered the art of scale. Similarly, because he does not quite understand real distance compared to perspective, the surrounding terrain is actually relatively close, but blurred to appear farther away. Death adds a large golden wheat field to the grounds after the events of "Reaper Man". There is also a tree swing, created by Death for his granddaughter Susan, which swings through the trunk of the tree. (There is a joke common among engineers that pictures a rope-and-board swing as envisioned by various corporate entities. The last illustration is usually the simple swing labeled "what the customer wanted". The one in which the swing passes through the cut-through trunk of the tree—the upper part of the tree being propped up by sticks under the branches—is usually attributed to engineers. Many of Pratchett's fans work in engineering and science.)
