I know a few, and for all you know, your curse is what some would call "The Will of Karma" as in, your curse acted in accordance with karma.
what most who believe in karma fail to realize is that universe is NOT random, and everything affects everything else, the only variables are living creatures, and the greatest variables, are humans and astral beings.
If someone beats thier wife, and then a week later you get pissed at them for some random reason and whoop thier a$$, people would say that you just got bad karma because of that.....but if your the person getting the a$$ whooping, people say that was you getting your karma back.
its all just another form of guilt, and I for one refuse to accept it.
I have a few curses, tell me what you need them for and your level of experience and I might hand one out.
