Undead is a term used to refer to a wide variety of beings that have escaped death, whether by their own machinations (such as Belladona), at the hands of others (such as the dryad zombies of Forest Watch), or through coalescence (such as King Ugrach). The entire Underworld is populated by the undead.

The thurible of Soulbleed artefact allows its owner to raise slain adventurers, turning the unfortunate person into a reanimated minion.
