Apophis, known as Apep: An Egyptian monster living in perpetual darkness. This snake god is the chief of the antagonists of the sun god Ra and each night he tries to stop the sun god's barque on his journey through the underworld. In the struggle between light and darkness, the monster is wounded by the divine entourage of Ra with knives and spears. The god Seth and the god Mehen were often depicted defending the solar barque.
Apep is the personification of darkness, evil, and chaos. Occasionally, the battle was decided in his favor, causing a solar eclipse, but his victories were of short duration for Re always triumphed in the end. Eventually, Apep was slain by Ra, who cut up his body and burned it. The Greeks referred to him as Apophis.
Amaunet: An Egyptian mother goddess, called the "Hidden One". She is the personification of the life-bringing northern wind. She belongs to the Ogdoad of Hermopolis. Within this group of gods her consort is the god Amun. She is referred to as 'the mother who is father' and in this capacity she needs no husband. Amaunet was regarded as a tutelary deity of the Egyptian pharaohs and had a prominent part in their accession ceremonies. She is portrayed as a snake or a snake-head on which the crown of Lower Egypt rests.
Loki: Loki is one of the major deities in the Norse pantheon. He is a son of the giant Farbauti ("cruel striker") and the giantess Laufey. He is regarded as one of Aesir, but is on occasion their enemy. He is connected with fire and magic, and can assume many different shapes (horse, falcon, fly). He is crafty and malicious, but is also heroic: in that aspect he can be compared with the trickster from North American myths. The ambivalent god grows progressively more unpleasant, and is directly responsible for the death of Balder, the god of light.
Loki's mistress is the giantess Angrboda, and with her he is the father of three monsters. His wife is Sigyn, who stayed loyal to him, even when the gods punished him for the death of Balder. He was chained to three large boulders; one under his shoulders, one under his loins and one under his knees. A poisonous snake was placed above his head. The dripping venom that lands on him is caught by Sigyn in a bowl. But every now and then, when the bowl is filled to the brim, she has to leave him to empty it. Then the poison that falls on Loki's face makes him twist in pain, causing earthquakes.
On the day of Ragnarok, Loki's chains will break and he will lead the giants into battle against the gods. Loki is often called the Sly One, the Trickster, the Shape Changer, and the Sky Traveler.
Angrboda: A giantess and the mate or mistress of the trickster Loki. Angrboda ("herald of sorrow") spawned three monsters: the gigantic wolf Fenrir, the Midgard Serpent Jormungand, and the goddess of the death Hel. The gods abducted the children from her hall when they learned just how dangerous they were.
