Dragons of Autumn Twilight is a fantasy novel by Margaret Weis and Tracy Hickman, based on a Dungeons & Dragons game session. It was the first Dragonlance novel, beginning the series in 1984. It is the first in the Chronicles trilogy, which, along with the Dragonlance Legends trilogy, are generally regarded as the core novels of the Dragonlance world. The Chronicles trilogy came about because the designers wanted novels to tell the story of the game world they were creating, something to which TSR only reluctantly agreed. Dragons of Autumn Twilight details the meeting of the Companions and the early days of The War of the Lance. It corresponds with the first two Dragonlance game modules, DL1 Dragons of Despair and DL2 Dragons of Flame, but the novel has a different ending from the modules. It introduces many of the characters that are the subject of many other novels and short stories.
Dragons of Autumn Twilight follows a pattern with the other novels in its series, Dragons of Winter Night and Dragons of Spring Dawning, as they all start with Dragons, followed by a series of seasons, Autumn, Winter, and Spring, as well as a series of time, Twilight, Night, and Dawning.
Margaret Weis includes allusions to A Christmas Carol by Charles Dickens, one of her favorite stories. References include But there was something disquieting about him—secret, silent, self-contained, and solitary as an oyster and The fate of mankind is my business, turning the quote from meaning good to meaning harm.
Libris Mortis: The Book of Undead is a book which is an official supplement for the Dungeons and Dragons role-playing game, version 3.5. It is about the fictional undead within the D&D universe and comprises seven chapters, introducing new content for Dungeon Masters and players, as well as providing general information about undead.
It was received positively by reviewers, with praise for its material for Dungeon Masters and its illustrations, but received criticism for its weak player-oriented content. The book was the second in the series of books about specific monster types, the first being Draconomicon. Similar books published since include Lords of Madness. Libris Mortis included content from older books, such as Tome and Blood and the Book of Vile Darkness, that had been reworked.
