Cursing

Cursing: The use of magic that implies harming another person, or protecting objects, or property, to punish a thief or two.

Harming Curses
Typical things like insanity, bad luck, etc. The possibilities are limited only to the curse caster's imagination.

Protective Curses
Are placed on objects that are dear to the caster. Like an heirloom, or journal. Even on their houses if they are that paranoid. These curses can only do anything if someone where to take said object, or enter their threshold, without the caster's specific permission. These ones are not entirely evil. (keep that in mind.) However there may be a few "jerks" (Trying to keep things reader friendly.) who will trick people into falling victim to these curses.
