Source of All Evil

The Source of All Evil is the title given to the most powerful demon and ruler of the Underworld.

The Source itself is an essence of pure evil, which possesses and merges with a new host each time it is vanquished. However, the vast majority of demons is unaware of this truth, believing that each Source is a new demon risen to power.

Background
The Source of All Evil is the ruler of the Underworld and must be coronated by a Dark Priest in a dark ritual, involving a Grimoire. Many demons seek to claim the title of the Source. The most prominent Source of All Evil was the demon known as the half-faced Source, who had been in power for centuries. His face was mutilated from his battles during his rise to power and only a few demons had ever seen his face. This Source was the ruler of the Underworld for centuries and defeated all opposition until he was vanquished by The Charmed Ones.

The next prominent source of all evil was the hybrid demon, Cole Turner, who was possessed by the life essence after the previous Sources vanquish. The essence made him whole again, filling a "void" that was allegedly left behind from the vanquish of Cole's demonic half. However, Cole's love for Phoebe proved too strong for the Source to beat and he wanted her as his queen. Cole was then guided by the Seer in his attempt to reorganize the Underworld and to conceive an heir. He eventually managed to marry Phoebe in a dark wedding and together they conceived a child that would be pure evil. Cole was then coronated as the new Source of All Evil with Phoebe as his Queen.

The Source's Heir and Leah
See also: Leah

300 years ago, The Seer gave birth to the daughter of the Source of All Evil. When Leah was born, the Seer got a vision. She saw Leah powerless. To avoid that the Source found out about the child, the Seer gave her away to a gypsy family.

Leah grew up in a gypsy village without powers. When her adoptive mother told her the truth of her origins and why she was given away, Leah became outraged. That was when her powers appeared for the first time.

She learned how to control her powers and then she started the search for her parents. She went to the Underworld and found out, after having some visions, that she was the Source and Seer´s daughter.

She waited for the right time to say to the world who she was and so be recognized as the Source of All Evil.

She will try everything to get to her goal, and that includes ending the Warren line.

The Evil Essence
The Source is an evil essence which possessed the bodies of numerous demons over the centuries. When the demon body is vanquished, the essence is transferred into another evil entity.

This means that every known Source was, in fact, the same spirit/demon, while demons, in general, believe that a new Source has risen. The essence will take a new host and merge with that host's own spirit, taking over their personality and consuming their own consciousness. The essence can also be reborn in beings who are related to its hosts by blood or those who are in possession of their powers.

The essence of the Source lies within its powers. When Cole gained the powers of the Source through The Hollow, the essence began to merge with him until they were the same. By merging with Cole, the Source began to share his love for Phoebe Halliwell.

Once Cole was vanquished, the essence went into their unborn son and used his powers to take control of Phoebe until the child was transferred to The Seer. When the Seer was vanquished, the essence became disembodied.
