Sakhmet

Sakhmet was a goddess of the ancient Nehekharan Pantheon associated with Morrslieb, which is why she was also called the Green Witch. She was the intriguing and vengeful concubine of Ptra, the sun god, and is jealous of the love of the Great Father for the human race. She was a very feared deity because she was associated with magic and the darkest rites, and with the most terrible creatures and spirits, always ready to cause damage and destruction among humans.

According to Nehekhara's tradition, every time Neru, the moon goddess, came out every night to protect men, the vengeful Sakhmet followed her, gazing grimly at the sons of the gods and intriguing to usurp the post of the Beloved wife of Ptra. Most nights, Neru triumphed, and her swift feet guided her through the sky; But from time to time, Sakhmet's ruses confused her and the Green Witch usurped Neru's place in the sky. When that happened, the whole region trembled with fear, for the creatures of darkness and the depths of the earth rose and used their evils against humanity.
