Rise of the Twilight Empire
Animates are the simplest, most common, and most varied kind of undead. They are little more than a body given animus from some source, usually a necromancer or a rift to the Shadowfell. They are generally mindless, though some of the more advanced varieties can have a low cunning that makes them especially deadly. They are relatively easily dispatched, the magics animating them can generally be broken by breaking the bodies that they are bound to, or killing the one who animated them. This category includes skeletons, zombies, and a host of other strange constructs.
