Undead (Dungeons & Dragons)

In the Dungeons & Dragons fantasy role-playing game, the undead are a broad classification of monsters that can be encountered by player characters.^{: 269–331} Undead creatures are most often once-living creatures, which have been animated by spiritual or supernatural forces. They range from mindless remnants of corpses such as skeletons and zombies to highly intelligent creatures like vampires and liches, but in whatever form they take they are typically malevolent and threatening. Like most Dungeons & Dragons monsters, the various kinds of undead creatures are "drawn from classical, medieval, and fictional sources", and have in turn influenced the use of these kinds of monsters in other games.
