What Significance Does the Number 7 Have on Game of Thrones?

The Faith of the Seven may bear the strongest reference to the number seven. This religion is the main religion in Westeros and "the New" in "the Old Gods and the New." The more fervent followers also carve the symbol of the faith — a seven pointed star — on their heads. The seven-faced God is represented by seven figures:

1. The Stranger
2. The Crone
3. The Maiden
4. The Father
5. The Mother
6. The Warrior
7. The Smith

PS: The root of the terms "sept," "septon," and "septa" mean seven.
