Lily Sunder was a professor of apocalyptic literature who fell in love with an angel only to have him and her daughter murdered. After getting her revenge, Lily gave up her magic and sought to ensure her entry into Heaven to be reunited with her daughter.
In the late 19th to early 20th century, Lily was a professor of apocalyptic lore with a daughter named May and studied into angels seriously, eventually becoming fluent in Enochian. Lily's studies led her to a spell that enabled her to summon an angel and when she cast it, Ishim appeared. Ishim quickly grew obsessed with Lily, believing he was in love with her. As a result, Ishim revealed all of the secrets of angels with Lily. However, Lily came to regard that Ishim was a monster obsessed with her.
Following her realization, Lily stopped contact with Ishim and eventually married the angel Akobel so that he could protected her from Ishim as well as taking care of her daughter. Upon learning of Akobel's relationship with Lily, an enraged and jealous Ishim secretly set out for revenge against Lily and her family. In order to do this, Ishim gathered his flight, including Benjamin, Mirabel, Castiel and two unnamed angels, and claimed to them that May was a Nephilim, and she and Akobel needed to be excuted for the crime they committed. When the angels arrived, Akobel orders Lily to take May and run away from the area, and then Akobel went to distracted the angels, knowing the reason behind Ishim's arrival. As Lily desperately gathered her things, Akobel was killed by Mirabel, and Ishim entered the house to confront her. After pinning a powerless Lily with telekinesis, Ishim accused her of leaving him for Akobel, and murders May infront of Lily in revenge. Ishim then leaves Lily alone mourning Akobel and May's deaths.
Over the next century, Lily began using her study of Enochian magic to give her immortality and the powers she would need to get revenge on Ishim and his flight. Using Enochian magic in such a way burned away a piece of Lily's soul each time, eventually resulting in her losing the ability to dream. Despite this, Lily pressed on, consumed by her revenge.
Following the fall of the angels, Lily finally saw her chance for revenge and took it. Lily was able to kill two unnamed angels of Ishim's flight with her new abilities and gain their angel blades for her own use.
In Lily Sunder Has Some Regrets, Lily eventually tracks down the angel Benjamin at the arcade where he was playing the game Rampage. Lily didn't faze when Benjamin didn't seems to recognize Lily, and the angel attempted attacked Lily with his angel tricks. Those new powers Lily gained help her become immune to Benjamin's angel tricks, resulting in both Lily and Benjamin armed themselves with angel blades. Lily battles Benjamin who proves to be no match for her who effortlessly pinned the angel up against a wall. After Benjamin begs for help using distress signal, Lily quietly commented that she had been waiting so long, and then Lily quickly stabbed Benjamin in the abdomen with an angel blade before left the angel's lifeless vessel to be found by the bartender.
After killing Benjamin in the arcade, Lily travel back to her hotel room and spend times mediating on her own. At some points after the Winchester boys and Castiel arrived at the arcade where Lily and Benjamin fighting earlier, Lily bolts up from her bed where she presumably have been mediating for possible assailant and murmurs "Castiel." After pressed a kiss to an old-time photo of her daughter, Lily goes after the three surviving angels of Ishim's flight who took part in the murders of her loved ones, the flight commander Ishim and two angel soldiers Mirabel and Castiel as they meet in a diner to discuss the situation. As Mirabel checks the alley behind the diner, Lily ambushes Mirabel, and quickly killed the angel with an angel blade. Ishim eventually comes out from the diner looking for Mirabel, and was shocked to find Lily who scores a deep wound on his side with an angel blade. Ishim retaliate by attempting to smite Lily, but Lily survive Ishim's smiting without much troubles due to her new powers. As Lily gains the upper hand against Ishim, Castiel intervened and slashes her with an angel blade, commenting on recognizing Lily from the murders of Lily's family members, before Lily kick Castiel across the alleyway in surprise. When hunters Dean and Sam arrives to help the angels, and threaten Lily with their firearm, Lily tries to convince them to allow her to get her vengeance mission, unwillingly to harms humans in her process of getting the revenge she want. When they refuse to let her go, Lily lets off a massive blast of light that blinds everyone and flees in her rental car.
Returning to her hotel room, Lily heals her wound, and later departs to find Ishim and Castiel to get her revenge. Much to her surprise, she is confronted by the Winchesters who had managed to track her rental car after Sam remembered the license plate during her escape. When the Winchesters attempt to talk her down as they believe her daughter was a Nephilim, Lily tells them the truth about what happened the day Akobel and May were murdered, bursting into tears as Lily do so. Inclined to believe Lily but needing more solid proof, Dean heads off to confront Ishim while Sam stays with Lily. While they waiting, Lily explain everything from how she uses the fall of the angels as advantage in her quest of vengeance and study Enochian magic instead of making the demon pact, and Sam finally agree to help her so she is willing to be patient further. Concerned by her words, Sam agrees to take Lily to confront Ishim.
Arriving at Ishim's church safe house, the two find Castiel severely weakened and Dean cornered by the rogue angel. Armed with an angel blade, Lily engages Ishim in battle with the two hunters attempting to aid her without success. Having been fully healed by Castiel, Ishim proves to be more than a match for Lily who telekinetically flings him against a wall. However, Ishim warned Lily that she can't hold him there forever and fight through Lily's hold with little effort, slowly advancing on her. As the Winchester boys and Lily helplessly watch, Ishim eventually reaches Lily and prepares to kill her with his angel blade. To everyone's shock, at the last moment, Castiel stabbed Ishim from behind with an angel blade of his own. As Lily stares at him in shock, Castiel tells her that "you held him for long enough."
Following Ishim's death, Lily was left alone to stares blankly down at his dead vessel and the imprint of his broken wings. The Winchester boys question whether or not Lily will give up on her revenge now that Ishim is dead, but Lily isn't sure whenever she could give up or not as revenge is all she's had for over a century. Now knowing the truth about what happened in 1901, Castiel prevented Dean from threaten Lily further, and then Castiel apologizes to Lily for his prominent role in murdering two of Lily's family members hundreds years ago. Castiel states his ignorance wasn't a proper excuse and went on telling Lily if she leaves and finds out she can't forgive him, that Lily can return to get her revenge on Castiel whenever she wanted. In tears, Lily thanks Castiel and leaves the area.
In Byzantium, Sam calls Lily in hopes that she can translate the prophet Kevin Tran's notes on the Angel Tablet and find something that can help them to bring back Nephilim Jack from the dead. Lily, now an old woman due to no longer using Enochian magic to keep herself young, is unable to read the notes, but suggests using her magic to save Jack. Lily proposes using a piece of Jack's own soul to sustain his body, but requests that in exchange, the Winchester boys ensure her entry into Heaven. Lily explained to the Winchester boys that she has stopped using her magic as she still has a sliver of her soul left and when she dies, she wants to be reunited with her daughter in Heaven.
As Castiel goes to Heaven to search Jack, the Winchester boys summon Anubis who agrees to judge Lily's soul. Anubis' Abacus determine that Lily will go to Hell upon death and he insists that he can do nothing to change her fate. Anubis explains that a person's own choices during their life determine their final fate and the Winchester boys are forced to let him go. Lily prepares to departed, but Dean begs her to stay and help them so that they won't have to suffer the loss of a child as she did. Lily finally agrees to stay and help them.
As Dean prays to Castiel, Lily performs the ritual to use Jack's soul. After Castiel resurrects Jack, Sam quickly provides him with the incantation Lily wrote out and Jack completes the ritual, curing his condition. Dean thanks Lily but finds out unbeknownst by anyone else, Lily suffers a fatal heart attack right after Jack's resurrection, and Lily quietly sits in a chair and passed away.
In another realm, she is greeted by Anubis in the afterlife much to Lily's confusion as why she end up here. Anubis offers Lily another chance to weigh her soul, and she does so . This time, according to Anubis's scales, Lily's soul is determined to be worthy of Heaven. Anubis implies that Lily knew that helping resurrect Jack would be fatal to her and that her selfless decision to help anyway was what tipped the scales in her favor. Anubis tells Lily to greet May for him, implying that Anubis knows Lily's daughter, and Lily smiles in peace and happiness, as she prepares to be reunited with her daughter at long last.

Lily was once a intelligent and kind-hearted woman who cared for her daughter, May very deeply. Lily's fascination with angels eventually led her to summon Ishim, a wrathful angel who wanted Lily all for himself. When Lily realized who Ishim truly was, she chose to cut off contact with him forever, and went on to start a new life with another angel, Akobel, who was the opposite of Ishim. This peaceful life ends up fueling jealousy from Ishim, who arranged the demise of both Lily's angelic husband and daughter as punishment towards Lily.
From that point on, Lily began to change, becoming vengeful and willing to sacrifice her own existence in order to get revenge on Ishim's flight who took part in the murders of her loved ones. Lily's use of Enochian magic gradually burned away her soul, turning Lily into a dreamless and murderous individual who saw revenge as her only goal for more than a century. After the death of Ishim, Lily admitted she wasn't sure she could give up on her revenge as it had been all she had known for so long. In spite of the fact that the last angel she was chasing (Castiel) saved her life, she still wasn't sure she could forgive him. After Castiel's apology and offer to allow Lily to return for her revenge against him at a later date if she wanted, Lily appeared to finally let go of her hatred and vengeance and move on with her life, tearfully thanking Castiel.
In order to enact her revenge, Lily developed a great deal of patience until the fall of the angels giving her the advantage in getting her hands on her desired targets. Despite Lily experiencing the increasing loss of emotions for over a century, Lily still remembered her daughter and Akobel fondly, and could still feel sorrow by the time she encountered Ishim again. She also showed reluctance to harm and kill innocent humans, pleading with Sam and Dean to back down, and later deciding to share the true story instead of attacking them. With Ishim's death and Castiel's apologies for what he had done, Lily was left to accept that her journey was over and choose move on with the life she had.
Following her time after revenge, she gave up using her powers and allowed herself to rapidly age as she intended to save a sliver of her soul in order to go to Heaven and see her daughter. She made amends with Castiel, despite hating him for a century and helped in trying to save Nephilim Jack. After Anubis determined Lily was going to Hell no matter what happened, Lily felt empty and nearly gave up on saving Jack until Dean remarked on her inhuman nature. Lily related herself to the Winchesters on losing a child and stayed to help, though the cost happen to be Lily's own life. However, Lily was surprise when Anubis offered her another chance to weight her soul, and Lily was happy that the new result was her entering Heaven instead and gently smiled at the thought of being with her daughter for eternity. Anubis implies that Lily knew she would die if she helped save Jack but did it anyway with the implication that it was this selfless act that allowed her to go to Heaven instead of Hell.
