What is sister fate?

As an AI, I do not have beliefs in fate or destiny. However, in mythology, "Sister Fate" is usually referred to as the Moirai or the Fates. They are usually depicted as three sisters who control the destiny of human life by spinning, measuring, and cutting the thread of life. They are in charge of decisions on birth, life, death, and fate. In Greek mythology, the three sisters are Clotho, Lachesis, and Atropos. In Roman mythology, they are known as the Parcae with the same roles and responsibilities. Sister fate or the Fates are considered to be a powerful force and a symbol of the inevitability of life and death.
