Sariel
According to the Book of Enoch, Saliel's task is to protect human souls from sin, and he is also the angel in charge of the moon. In ancient times, people believed that the moon was where the souls of the dead were stored. Saliel may be the angel who imparted knowledge to Moses, or he may practice healing like Raphael. Since Salil is the angel of the moon, and the moon was always associated with some bad things in ancient times, Salil is also said to be one of the fallen angels.
But in "The Battle between the Sons of Light and the Sons of Darkness" in "Dead Sea Document", Salil is in the battle sequence of the Sons of Light. We can only say that Salil is an angel with dual identities.
Because of his position, Sariel is said to have the so-called "Evil-eye" ability. The actions of creatures stared by the evil eye will be blocked. Ancient Europe and the Middle East regarded this ability as a symbol of terror, and Sariel was naturally regarded as a devil.
