Arella

She is the former bride of the all-powerful interdimensional demon Trigon, who had cunningly seduced her, in human form, to have someone to bear a half-human, half-demon daughter who becomes Raven.

Born in Gotham City, Angela Roth was a depressed, aimless teenager who fell in with cultists after running away from home.

The members of the cult promised to keep her fed and well-rested in exchange for taking part in a secret ritual to appeal to Trigon, who was to manifest on Earth.

Upon discovering his true form, Angela became horrified, but was unable to escape Trigon, who continued to assault her.

After failing to receive any help from state agencies, Angela attempted to kill herself with sleeping pills in an abandoned alleyway.

But when Deathstroke was forced to kill his son Jericho, the corrupted souls of Azarath left him and possessed Raven, turning her evil once more.
