Malum

Malum is best known as the Source of All Evil in the story Something to Be.

Background
Malum, also known by the alias John Malum, is an ambitious demon who climbs the ranks of the Underworld to become the Source of All Evil around the same time as the new Charmed Ones came to power.

He is known for his unique style of running the Underworld as a business. Prior to becoming the Source of All Evil he attended Harvard Business School and recieved his degree. Malum puts major emphasis on thinking like a human and using that as an advantage.

In the episode "Devil's Thunder", it is revealed that Malum was originally hired by the Triad to track down the Gemini Protestatis Stones. Rather than doing so, however, he took the opportunity to arrange for the murder of Paige Matthews. The Underworld was so inspired by her death that Malum was corinated as the Source of All Evil. Since then he has focused on organizing the Underworld and resurrecting a sufficient army. He is in bad relations with the Triad who did not intend for him to come to power.

Malum is married to the demon Aliah. Her son, Delezar also known as Jack, is the cause of much of his frustration. Jack's bloodline is responsible for the rise of the Brotherhood of Thorn which Malum utilized to kill Paige and continue infilitrating the new Charmed Ones. Not much has been said of Malum's overall power. While he is obviously a demon, he seems to command more than fight. Aliah often antagnoizes him for being jealous of Jack's biological father, Cole Turner.
