Faerie Courts

The Faerie Courts are the organizations of the Faeries or Sidhe. There are the Summer Court and the Winter Court.

Order
Each Court has three Queens and a Knight. The eldest of the Queens is called either Mother Summer or Mother Winter, depending on to which court she belongs. They holds no official power over the court, but are still very powerful, with unseen connections. The ruling queen is often referred to as either the Winter Queen (Mab), or Summer Queen (Titania). She controls each court, whose power waxes and wanes with the seasons. The youngest of each court is the Lady, Summer Lady and Winter Lady. She is considered to be Queen in training.

Details
Faerie Queens can not kill anyone who isn't attached to the courts through birthright or bargain. They can't kill directly but the can do a lot indirectly like trick a person to do something lethal to them such as walking into quicksand, or turn them into a stag and set the hounds after them, bind them into an anchanted sleep, among other things.

The Power that a Sidhe Knight has comes from the Queen. When the knight dies, the power snaps back to the Queen.

Sidhe Knight
A Sidhe Knight is mortal and a champion of one of one of the Sidhe Courts. There is usually only one Knight per Court at a time. The Knight gets powers that are in line with his court. That power comes from the Queen and it is substantial. It returns to the Queen at his death to be passed on to the next Knight.
