Fetters: Fetters are things that keep you bound to the world, people, places, objects. You invest points from your base Aether into Fetters when the game begins, as many as you want, the more points inserted the stronger the emotional bond to it and the more anchoring it is (e.g. A pen you carried for a few months at school during exams that you were quite fond of may be a 5 point fetter, the birthing shawl you were swaddled in as a baby that you carried your entire life and is the only thing you have from you mother as she died in Child birth may be a 300 or more point Fetter)
For every 10 points you have invested in a fetter it has a skill, this skill is like your skills but only works on/armound the fetter (e.g. Posession, but only on people wearing the fetter, or Poltergeistery but only on the fetter), this represents the fact you are more anchored and secure around the fetter, stronger, people and places can also be fetters however they are more difficult as it is more difficult (People have one skill per 20 points invested, Places 1 skill per 40 points invested). Fetters also have another use, if a ghost loses his way and starts to move beyond the viel before his purpose is complete, the fetter can act as a beacon, drawing him back and helping him to remember its goals, when a ghost reaches 0 Aether, half the Aether invested in the Fetter is transferred over to it, the rest is lost, this leaves the Fetter at 0 Aether, it is no longer a Fetter. However lost Fetters can be refilled/Reattached to the ghost for the origional cost of the Fetter +10%, which returns it to its full state. Fetters can be destroyed by being physically destroyed, exorsised or killed.
