Eunha was born on Jeju, an island province in South Korea, and at one point immigrated to the United States. At one point, Eunha married a fellow witch named James and had a daughter with him, Hattie.
Soon after they adopted a girl from the excommunicated Horangi clan and told her her birth parents were sarams, non-magical, teenagers and named her Riley. They persuaded the elders to have her elemental affiliations looked at and all four were fire, with elements only repeating once it was unheard of, and Riley was forbidden from practicing magic.
One Saturday, about a month before his daughter Hattie is to try to receive her Gi bracelet, she is helping Hattie rehearse for her initiation. She informs Riley that the elders have refused to give her an initiation. After Hattie rants about it being unfair and Riley jokes about a way to share her magic with her when she accidentally reveals to her daughters that their is a way, but it is temporary and dangerous. Later during services at temple, which they are late to, they watch as one of the elder's granddaughter has her elemental affiliation revealed, and are warned about an exiled clan trying to get back into the congregation.
Two days later on Hattie's thirteenth birthday, she watches with her husband and Riley as Hattie completes her initiation and becomes a full member of the Gifted Community. She and her husband watch in shock as their daughters perform a power sharing ritual. After her sister reveals that Riley is really a Horangi, they sadly confirm it. The family and her sister are given a choice to make by the end of the week, either all of them are stripped of their magic and excommunicated or Riley is banished like the other Horangi. After Eunha and her husband find the letter his daughters left about summoning Mago Halmi, they try desperately to call them to no avail.
She and James have a Samjogo seer track her to the Horangi and they and Okja go to get Riley. When they arrive Emmett Harrison fills them in and she, her husband, sister, daughter, Emmett, Sora Kwon, Austin, and Taeyo go to a shed to talk. They hug Riley and accuse her birth parents of kidnapping and brainwashing her. When Riley accuses her sister of a coverup, Okja reveals her suspicions of Bongjoon Pyo, the Samjogo elder, of being behind it due to his recent erratic behavior. The group form am uneasy alliance and head to Los Angeles. They arrive at Mr. Pyo's place of work and, after Taeyo hacks into his calendar to make an appointment for his relatives, they walk right in. They find him in a meeting and, when he sees them, runs as they give chase. They corner him in his car as Sora, Austin, and Taeyo subdue him. Riley asks why he framed the Horangi. Mr.Pyo tells them Sookhee Harrison was behind everything before he comes to the realization that she was possessed by the Cave Bear Goddess as part of a plan for her and her sisters to destroy the artifacts, which are actually pieces of the dark moon and dark sun, to erase their sin so that they can enter the Mortalrealm and do what they please with humanity. After realizing the Cave Bear Goddess can possess members of the Gom, Riley asks if they can sever the clan's ties to her. Although hesitant at first, Okja reveals a spell exists and she and her husband agree to it. Just then Areum arrives and says the Dokkaebi know where the artifact is. As they question where to even find a dokkaebi, Mr. Pyo says one lives in the forty-fourth room on the forty-forth floor of the temple. They leave the elder behind and, after stopping at the Tokki elder's house for a sleeping potion, they reach the temple and argue over who is going to make a deal with the dokkaebi. When they reach the room, the decide on the Ohs going in. As her she drinks the potion, she falls asleep as her husband and daughter watch over her. As she speaks, the goblin agrees to give her the star exchange for the life of one of her daughters, something she couldn’t do. She wakes up sobbing ten minutes later and relies what happened as James comforts her.
The others enter the room and, as Riley had their memories of her erased to find the last fallen star, they do not recognize her and are surprised that she knows about their plan to sever the Gom from the Cave Bear Goddess. After she returns Emmett's ring and takes out Taeyo's compass, she believes it is the last fallen star and they head to the Gi Sanctuary. The Cave Bear Goddess arrives and asks Riley for the star. She then requests Hattie and the goddess obliges. She, James, and Riley hug Hattie, who is incredibly thin with a gray hue to her skin. Suddenly Hattie starts to spasm before speaking in the voice of Sookhee Harrison. After she explains to her son what she did and how she regained her sense of self, she turns into a jaguar and goes to the afterlife. Riley berates the goddess for not returning Hattie, the goddess responds that, as she and the other goddesses are the daughters of Mago Halmi, all others are beneath them. Okra then starts the spell to sever the goddess from a Gom, binding the two with thread. Riley goes to cut off threads, but fails to do so as she realizes to late that the compass is not the star. As the Cave Bear Goddess berates Riley, for betraying her, Riley says she is powerless in the Mortalrealm without a host. Just then the goddess tries to possess Okja. She and the others try and fail to stop the goddess. She heals James after the goddess sends him flying at the Gom pews and they both heal Areum after she shields Riley from an attack. She and the others are shocked when Riley announces that she is the last fallen star and watch as she destroys the statue of her clan's patron goddess, expelling the Cave Bear Goddess from her sister and the mortalrealm.
As things calm down, she and James thank Riley for returning their daughter to them. As they continue to mourn, Riley is given a wish by the Haetae to undo anything from her past and she decides to resurrect Hattie. He does so and, after a delay, Hattie is resurrected. They all cheer and the Ohs hug and promise to find a way to restore their memories of Riley as they fill Hattie in.
