The Seven-in-One GodEdit
Though the Faith teaches that there is a single deity, it has seven "aspects" or "faces". For this reason, the deity is often referred to as the "Seven-faced God". In practice, many devotees will refer to the aspects as "Gods" plural, though priests of the Faith will attempt to stress the theological nuance to their followers that there is indeed only one God, the "Seven-in-One" deity. This has not stopped the commonly heard exclamation "Gods be good!" from being used pervasively throughout the Seven Kingdoms. The Seven are referred to as "the New Gods" or "New God" to distinguish them from the Old Gods of the Forest worshiped by the First Men
According to tradition, the Seven manifested themselves to the Andals, the inhabitants of the Hills of Andalos in the continent of Essos, six thousand years before the War of the Five Kings. Soon after, the Andal Invasion of Westeros began.
Each of the Seven aspects symbolizes a different part of life and are prayed to for different purposes. They are known as the Father, the Mother, the Maiden, the Crone, the Warrior, the Smith, and the Stranger.
The Father represents divine justice, and judges the souls of the dead.
The Mother represents mercy, peace, fertility, and childbirth. She is sometimes referred to as "the strength of women".
The hymn Gentle Mother, Font of Mercy is dedicated to Her praise.
The Maiden represents purity, love, and beauty.
The Crone represents wisdom and foresight. She's represented carrying a lantern.
The Warrior represents strength and courage in battle.
The Smith represents creation and craftsmanship.
The Stranger represents death and the unknown. It is rarely prayed to.
The Stranger is served by an all-female monastic order, the Silent Sisters, who are tasked with preparing the bodies of the dead for funerals. For this reason they are also known as the "Wives of the Stranger".
The Stranger is depicted as neither male nor female, thus the number of male and female aspects within the godhead is equal: three males (Father, Warrior, Smith), three females (Maiden, Mother, Crone), and one who is neither.
Unlike the other aspects which are represented as human figures in artwork, because the Stranger represents the unknown it is often portrayed in a wide variety of forms, often frightening. Sometimes it is represented as a skeletal figure, or a non-human creature possessing various animalistic features.
