Fey Curses and Fey Marks: Lesser and greater fey curses and marks are left to the discretion of the local Plot Committee. They are always Local Campaign Only and do not transfer to other campaigns unless agreed upon by the Plot Committees of the campaigns involved.
Lesser fey curses are generally no more powerful than Battle Magic spells while greater fae curses can be very powerful plot effects. How these curses are administered, removed and carried out is up to the local Plot Committee.
