Like the other residents, Greyerl signed a contract with Labrelum Inc. to live in Labyrinthia and have her memories repressed. However, Greyerl's new life was one of poverty. Her circumstances were exacerbated by her being one of the town's witches; as the laws of Labyrinthia stated that all witches were to be executed, she hid this from her parents.

One winter, her parents were unable to pay the rent for their house and facing eviction. Attempting to get the needed money, Greyerl intended to cast Goldor on a fallen leaf to turn it to gold and then sell it. However, the spell was accidentally cast on her pet goat Margaret. Horrified, Greyerl attempted suicide by drowning herself in a river. She was saved by Belduke, who paid the rent and allowed Greyerl to stay at his house as his butler, with her parents' approval. Greyerl pretended to be male to ward off suspicion, as only females could be witches.

Five years later, Greyerl and Belduke witnessed a bell tower appear in the Town Square after a lightning strike; Greyerl noticed a change in Belduke's personality after this. She later noticed him writing a letter that mentioned "exposing the witch". Believing that he was referring to her, she plotted to stop him. She placed a soporific inside his drink of tomato juice before giving it to him in his office. Later, using the Godoor spell, she created a portal behind Belduke so she could take the letter without him noticing. Reading that it was addressed to the Storyteller, Greyerl strangled Belduke, who did not resist; unknown to her, he had committed suicide by poison. She then took the contents of the envelope and replaced it with blank paper.

The following morning, Emeer Punchenbaug helped Greyerl break down Belduke's door. As they entered the room and saw Belduke's body, Greyerl left and called for the knights, thus avoiding suspicion of evidence tampering. Greyerl kept Belduke's letter with her, but could not bring herself to either read or destroy it.

Three months after Belduke's death, Greyerl met Phoenix Wright and Maya Fey. Learning that they were investigating Belduke's death, she allowed them to explore the house. During the investigation however, a disguised Darklaw appeared and cast Goldor on Hershel Layton in Belduke's office. Fearing suspicion, Greyerl removed the Godoor gem from her Talea Magica and replaced it with the amethyst she wore around her neck to make it look like a Familia gem. She then created a portal from her room to Belduke's office and dropped the sceptre. Fey was accused of being the witch who cast Goldor on Layton and was arrested.

Greyerl claimed the following day that she was awake all night looking for a way to undo the spell on Layton. During Fey's trial, she released her long hair and confirmed Wright's theory that she was in fact a girl, but she denied being a witch. She testified about the events surrounding Belduke's death, but continued to deny involvement. Wright was eventually able to prove that Greyerl was a witch and demonstrated that Belduke had committed suicide, meaning that Greyerl, contrary to what she thought, was not guilty of murder. She then read the letter, realizing that the witch Belduke was referring to was not her, and that he had cared about her the whole time. Seeing that she was mistaken about her master, Greyerl broke down in tears.

Though she was innocent in casting Goldor on Layton and killing Belduke, she was still revealed to be a witch and therefore sentenced to be executed. Espella Cantabella intervened and offered her life instead by claiming that she was the Great Witch Bezella. Though Greyerl was spared, Fey leapt into action to save Cantabella, and was sent into the flames instead.

As the court decided against executing her for being a witch, Greyerl was placed inside the Deathknell Dungeon to await a new sentence. Later, Wright, Cantabella, and Luke Triton encountered Greyerl in one of the cells. She apologized for Fey's apparent death, but Triton informed her that they earlier met Kira, who was alive and well after being sent to the flames, meaning that Fey could still be alive. Feeling indebted to the group, Greyerl distracted the guards so they could enter the courtroom and examine the fire pit mechanism undetected.

After the final witch trial and the revelation that magic had been staged, Greyerl was released from prison. She returned to Belduke's house to continue her duties tending to his home.
