Later Trigon revealed more of Raven origins. He has a son from each of the Under-Realms he's conquered, but Raven is his only daughter. Trigon let Raven's mother, Arella, live because he needed Raven to be raised by humans so she could recreate the seven under realms in her own image. Arella fled with her daughter to Azarath where the monks taught her how to control her bad side and avoid Trigon`s influence on her till her escape years later.
After her capture, Raven spent time in the Under-Realms where time flows faster or was compressed. Trigon considered he just needed to liberate her by keeping her close to him, letting her supressed heritage reemerge and not directly control her to remake Raven in his own image.
Impressed after having fought many battles by his side,Trigon handed her the Throne of the Under-Realms to rule as a Queen.
Now, Raven supposedly is allied with his father to defeat the Teen Titans, but Trigon is weary of her as he knows she is making her own plans without his blessings.
It is not determined exactly which side she is on as she has so far remained vague about her intentions and has taken mental control of Beast Boy before they seemingly attacked the Teen Titans who were fighting Trigon and Psimon. She wants to help the team defeat Trigon but is a mystery If she is someone to be trusted. Tim Drake has so far decided she remain around despite Wonder Girl's objections, due to what her armor is telling her. Before Raven can explain anything, she looses control of herself and launches herself at Wonder Girl, though the reaction is due to the proximity of Raven's three brothers; Belial, Suge and Ruskoff who had just arrived to retrieve her for their father.

Raven free of her father`s control- The New Teen Titans #39 - Loving You!
From around the time she reached adulthood Raven began exploring her mother's home world so that she would be able to deal with the various emotions she would come across. As she would reveal later on to the Titans, she had known for years that Trigon would invade Earth and that she had tried to coax Azarath into action, but their beliefs in total pacifism wouldn't allow it. Eventually Raven's patience with Azarath ended and she left its tranquility in favor of Earth, hoping the heroes dwelling there would aid her. However, Raven's heritage resulted in her request for aid from the JLA being rejected because Zatanna could sense the evil within her. Withdrawing, Raven instead looked elsewhere for allies to combat her father, finding the people she needed in those who were once called the Teen Titans, who had parted years ago. Dick Grayson was haunted by visions sent by Raven that allowed him to know of her and the others in advance, Wally West was saved from freezing to death on a mountainside by her before she had him fall in love with her, Donna Troy would suddenly find her old Wonder Girl outfit in her bag when she saw a mugger escape into a burnt down building, finding it to be her childhood home Wonder Woman had saved her from. She would ignite a spark of power in the alien princess Starfire that would allow her to free herself. Offer companionship to Victor Stone and inspire his father to build a suitable home for them. And finally she would subdue the anger Garfield Logan felt at how his life had turned out.
At first she hid her demonic past from her new friends but after encountering the Justice League of America (who had previously turned down her request for aid), Zatanna revealed this to her team. They felt betrayed at first but soon after Raven was kidnapped by her father. The team subsequently rescued her and imprisoned Trigon, though Raven still battled the remnants of his power. In the period following these events Raven would occasionally lose control of her powers in high stress situations, though with her father's increased control of her she could regain control. This was also at times a difficult era for the team as for instance Deathstroke infiltrated the team with an agent, Terra. Trigon would eventually return and took control of Raven, destroying Azarath in the process. Her team was forced to kill her so that her spirit could be directed to kill her father. She rose again, purged of her father's influence, but was not seen for a while (she was absent during the Crisis on Infinite Earths), her absence being one of many failings an angry Nightwing threw at Donna Troy for failing to investigate while she criticized him for being absent from the Titans due to Starfire's marriage to another tamaranian.
Arella however had kept searching on her own, following clues and rumors of a strange and sad woman that appeared out of nowhere and had amazing curative powers. However Brother Blood's followers were following the same leads and mother and daughter were captured in a swamp village that had been keeping Raven captured due to a vicious disease that plagued them. In her fragile state of mind, still not recovered from the battle with Trigon, Blood managed to brainwash Raven into his willing and unhinged servant. When Nightwing, as Richard Grayson, was captured while infiltrating Blood's complex, he was tortured in order to convert him, Raven would heal him each time so the torture could continue, believing Blood would set Richard free. Blood's first step was to reinvigorate his Church of Blood and had Raven and Azreal stage his own resurrection on live camera, the second phase of his plan was to join his powers with that of Raven in order to take control of the planet. The Titans, both the old and those who Donna had recruited, arrived to fight Blood but were unable to best him and ended up captured, while the Justice League had to abandon their assault to prevent Blood forced from doing too much damage, leaving a distraught Magneta to proceed alone. Magneta manages to free the Titans, while Arella is near-fatally wounded by Blood's torturer; the Confessor. Only part of Raven's own mind resurfaced when Jason Todd showed her what had happened to her mother, making her turn on the Confessor. She was then summoned again to Blood's side as he was again confronted by the Titans, Blood made a final mistake and fed Raven even more of his power, breaking his own control over her. Previously considered immune to Raven and her powers, Raven was now able to take her vengeance on Blood and utterly destroyed the ruthless egotisical maniac he was. Azareal escaped with Blood and left him with a brotherhood of monks, who couldn't help but notice how quiet and almost meek their new brother was while he guarded their sheep. Combined with the birth of Blood's first child, a daughter to Mother Mayhem, it was assumed to be the end of the Curse of Blood.
