The Fourfold Deception
The Seasons are a group of four individuals each representing one of the four phases of nature, each seasoin is linked to a blood line but in some circumstances an avatar will assend outside of this.
The positions of the seasons also act as the heads of the elvish society which is dictated by the changing of the year and as such before the avatar has acended another will rule in their place. The acention is either done ritually or happens upon the death of the the previous holder of the title. Within elvish socity they also have many important aspects to the role such as causing the season to change, if the ritual is not done or goes wrong the change of the worlds season can be affected, it is such a happening that caused the extended winter many years back, the lady of winter at the time was power hungry and held the land in winter for almost 2 years, it was only the birth of a new avatar of spring that allowed the other seasons to depose her and place the current Lady Winter restoring the balance.
