These characters can be categorized for most purposes as Villains. This is of course a fuzzy category as there may be good and evil in anyone, but these folks tend to share a few nasty characteristics which will tend to put them in opposition to those characters we tend to root for.

Some characters, such as the Sorceress in Green and Sethra the Younger (and perhaps even Vlad) are more morally ambiguous, but they belong in this category if they have been a villain in one or more books.
