Cursing at other Beings and emitting large amounts of negative energies spawn a Curse, a Spirit of misfortune. These spirits rarely live longer than the Being they infest, but some are kept artificially alive through Magic. The sole existence of a curse is to perform an energy flux that is associated with the 'luck' of a being, resulting in misfortune for the being. The stronger the curse, the more effect it takes on the persona.

Curses are referenced as the Terrors. Their devastating power has lead to many catastrophes and are used as a weapon in rare occasions.
