i had one on me for over 15 years and did not even know it. somehow i got in someones way back in high school. i guess they had acess to ancient dark majik. after the curse was gone, i asked myself what the difference between a curse and a spell was. i had been exposed to those as well. the conclusion i came to is that the curse is designed to have a permanent effect covering multiple lifetimes. where as the spell wears off. how they go about accomplishing this is not something i know or care to know. i just know now how to remove them. that is enough for me.
