The sordid details of Nualia's past as revealed by her captured journals and notes:

Nualia was a foundling, raised by the kindly Father Tobyn, Sandpoint's priest at the time. As a child, her unearthly beauty made the other children jealous or shy, and many of the superstitious townspeople wouldn’t leave her alone with requests to heal their warts, treat their infertility, and endless other awkward and humiliating requests over the years. By the time she came of age, she felt more like a freak than a young girl, and fell willingly into the arms of a local Varisian youth. They had many trysts in hidden locations, including an abandoned smugglers’ tunnel under the town, and before long Nualia found she was pregnant. The youth called her a harlot and fled, and when her father discovered her condition, he lectured her nightly, refused to let her leave the church, and unknowingly nurtured a black hatred growing in her breast.

She miscarried her child, a child whose monstrous shape was only briefly glimpsed before horrified midwives stole it away to burn it in secret. The shock of this put her into a coma, and as she slept, she dreamed unhealthy dreams. She became obsessed with a cruel demon goddess and the conviction that her wretched life was inflicted on her by those around her. She came to see her angelic heritage as a curse, and the dreams showed her how to expunge this taint from her body and soul, replacing it with chaos and cruelty. When she finally woke, she was someone new, someone who didn’t flinch at the plan to jam her father’s bedroom door shut and set the church on fire before fleeing.

She fled to Magnimar, where she enlisted a group of killers known as the Skinsaw Men to help her track down her child’s father and slay him. The leader of the Skinsaw Men gave her a medallion with a seven-pointed star called a “Sihedron medallion” and told her she had a larger role to play. Returning to Sandpoint, she found herself drawn to the brick wall in the smuggler’s tunnels where her child had been conceived. She bashed down the wall, and found a complex she refers to as the “Cathedral of Wrath” and the quasit Erylium, also a follower of Lamashtu. For many months Nualia studied under Erylium’s tutelage, and during this time received another vision from Lamashtu – a vision of a monstrous goblin wolf imprisoned in a tiny room. She learned that this creature – Malfeshnekor – was also one of Lamashtu’s chosen, and that if she could find him and free him, he would not only help her achieve her vengeance against the town of Sandpoint, but he would be key in cleansing her body of what she had come to see as her “celestial taint”

The notes go on to outline her plans to send an army of goblins against Sandpoint and burn the town to the ground, not only to offer it as a burnt offering to Lamashtu in the hopes of becoming a half-fiend, but also to fuel something she calls a “runewell” hidden in the tunnels below. The notes go on to detail how to cause something called a “sinspawn” to manifest from the runewell, and that if one were to overextend the runewell’s stores, it would be deactivated. Nualia isn’t sure how to reactivate it, and several times stresses that the runewell shouldn’t be used much until after Sandpoint is razed and the deaths of hundreds of angry citizens and goblins have refilled the well.
