Lilith

Lilith is a demon who on occasion possesses Sadie Hale's body.

Personality
Lilith is mischievous and seeks enjoyment out of every minute she walks the Earth. This causes her to have a more expensive taste and a thrill-seeking attitude. She is temperamental and slightly unstable with her emotions.

She would stop at nothing to protect Sadie, although they share a tumultuous relationship.

She has a tendency to enjoy violence, although knows the value of information often outweighs it. She is a trader of secrets and a master of an ironclad contract.

If she offers you anything, know it comes at a price.

Life Experiences
Not much is known about Lilith before Sadie arrived at Silas University. It is believed that she has been with Sadie for the past 7 years.

Lilith is related to Scribbles as an Aunt, although, demons rarely keep blood-relatives, so it is possible that they are merely very close.

Powers
As a demon Lilith has the typical ability to possess a human body.

She is highly resistant to injury, potentially, invincible.

She clearly has the ability to manifest her desired form of clothing, as well as on occasion, a baseball bat for which she cares deeply.

The full scope of Lilith's abilities has not been documented. But, there has been evidence that she has some kind of illusion or mind control specialty within her grasp.
