Arella unwittingly became the bride of the evil inter-dimensional being known as Trigon. Through this union, Arella gave birth to Raven and raised her in the peaceful realm of Azarath. Despite Arella's efforts, her daughter was bound to Trigon by a prophecy which would entitle the subjugation and destruction of all life. Arella forever gave Raven her love, even knowing what she was destined to become: A vessel for Trigon's evil. When the prophecy was about to come to pass, Raven desperately sought out Azarath for help, only to find the city at first apparently deserted. A white dove led her to her mother, who could, however, offer neither help nor comfort since the prophecy was inevitable. Right afterwards, it was revealed that the sound state of Azarath had been in fact a cruel illusion: The city was destroyed and in flames, and its people - including Arella - had apparently perished.
Azarath and its people were restored along with Earth when Trigon was defeated. Raven travels back to Azarath once again and the entire city is fully restored. Raven makes a point of visiting Arella to discuss with her why she is now free to feel.
Arella seems to be able to wield some sorcerous abilities, enough to leave a projection of herself and their realm for her daughter even after Trigon had devastated Azarath. It was then revealed that Azarath had already been destroyed, and that Arella may be dead. Although this is debatable, she must had given Raven her last words through a telepathic imprint of some sort. The true extent of her powers are unknown, though evidently they were unable to shield herself or Azarath from Trigon's own wrath.
