Lilith

Lilith is the wife of Lucifer and the mother of Charlie.

Background
Much like her husband, very little is known of Lilith, as the show's creators have chosen to remain silent on her character. They, however, have confirmed she is very important in regards to the overall story, suggesting a significant role in the future.

Based on imagery, she is presented as a tall woman, exceeding both her husband and daughter in height, with pale skin, long blonde hair and silverish eyes. Her most distinguishing physical characteristic is a pair of horns (a trait her husband ironically lacks) which noticeable differ depending on the image. Whether this is deliberate or a case of inconsistency is unknown.

During the pilot, Charlie contacts her for moral support after her disastrous interview. Unfortunately, the call goes to voicemail, prompting her to leave a long message instead.

Charlie
Charlie is Lilith's daughter. Their relationship seems to be close evidenced by the pilot, as she gives advice to her, and hints affection towards her daughter when Charlie calls her.

Lucifer
Lucifer is Lilith's husband, and the ruler of hell. It's unknown what their relationship is outside of being married.

Trivia

 * In The Bible, a Lilith (meaning; Nightjar, Screech Owl, Night Hag or Night-Monster) refers to a bird like creature fist mentioned in Isaiah 34:14 measuring in at almost 30 cm (12 in.) in length with a wingspan of 50 cm (20 in.) or more.
 * When asked if the Eden family (Adam, Eve, Cain, Abel) have some connection to the Magne as well, Vivziepop said that she can't say because it's part of the story.
