Walking Dead

Walking Dead is a semi-obscure term from the /tg/ lexicon which basically serves as a catch-all term for the myriad undead who aren't some flavor of vampire, lich, ghost or mummy.

The term originates from "Van Richten's Guide to the Walking Dead", a sourcebook for the 3rd edition Ravenloft setting of Dungeons & Dragons. The first of the Van Richten's Guides to be published by the Weathermay Twins, alongside their books on the Shadow Fey and the Mists (the latter was completely written, but never printed, due to license running out; it's instead been released into the internet), it covers the various breeds of undead that Van Richten himself had never covered: Obedient Dead (zombies and skeletons; creatures raised from the dead to obey a necromancer), Hungry Dead (creatures that rose from the dead to pursue a craving, like ghouls), and the Restless Dead (creatures that rose from the grave to complete a mission, such as revenants).
