The Seven Star cluster called by the Greeks as Pleiades is one of the most adversarial (note balanced) of the symbols representing the gods. The Seven Stars together can mean a negative or positive effect on events depending on the astrologers. MUL.MUL is represented by the Seven Evil Gods called Maskim are referred to as "seven malevolent phantoms of the flames". The Seven are not bound to these stars, yet utilize them when they are visable.

This no doubt presents a possible origin of the myth of the Seven Evil Gods encircling and attacking Sin. The Seven Stars are known as those who herald the power of Mars being Nergal-Erra, lusting for war and destruction when it suits them.
