Aliah

Aliah is best known as the Queen of Evil and the mother of Jack Mason.

Backstory
Aliah is introduced in the second episode of Something to Be as the wife of the Source of All Evil, Malum. She is an upper-level demon who marries for power and has been known to have several affairs with formidable demons. Though none have been introduced besides Delezar, she has mothered several other demonic children, many of whom have been killed.

As the Queen, Aliah is usually in the know of many of Malum's plans against the Charmed Ones and the Halliwells. She encourages her son greatly, though she is often pushing him to be more agressive in his demonic ventures and less soft. She defends Jack to her husband, even though she often scolds him. Aliah is rather opinionated and not afraid to use her power or spout off to Malum. She appears to be a very powerful demon and is very much the driving force behind both her husband and son.

Something to Be
Jack's father was not initially revealed but in the episode "All My Secrets" Aliah reunites with Cole Turner, who is Jack's father. It is clear that the two had a rather long relationship but it didn't work out. Aliah still has feelings for Cole who also returns affection for her. Aliah is bitter that Cole was not there for their son.

After finding out that his mother intended to kill Melinda on Valentine's Day, Jack disowns her.

Aliah's oldest living son, Damien Mason, makes his first appearance in the episode "Good Times Gonna Come." He is released from a mental hospital by Malum where he has been for the last six years. In this same episode, Jack confronts Malum for arranging an attack on Melinda. He fights both Damien and Malum but before being killed, Aliah appears with Cole. Cole and Aliah are able to save their son. Malum is outraged but demands that though he'll let Jack and Cole go, Aliah must stay with him.

Powers
As the Queen of the Underworld Aliah has displayed the ability to use fireballs and teleport. She can also use telekinesis. A majority of these powers Aliah has passed down to her son.
