A mythical Ancient Egyptian Deity, Set (or sometimes written as Seth), was the Brother of Osiris. A Dark Lord of The Underworld, it was Set who murdered his Brother (by chopping him to pieces). Osiris wife, Isis reassembled him long enough to conceive his Son Horus. Set is a God to be avoided , as his word means nothing . Set had his own Cult of worship (3,500 B.C.) Seth is described as having a Jackal head and a human body. He is also known as The God of Chaos.
