The Blight's Abomination

Before defeating Belos, Belos cursed Luz to die an agonizing death in three days. Luz defeats Belos and the next day, she starts coughing up blood, the curse starting up. The next day, she's coughing up even more blood as Eda takes her to the healing coven. The healing coven can't cure nor treat Luz and due to her violent coughing of blood, she loses her ability to speak. On the last day, Amity comes to visit her hospitalized girlfriend. They spend their last moments together then Luz screamed out of agonizing pain and after, she died. Amity, heartbroken, went into a depression. Everyone else went to Luz's funeral, everyone but Amity. A few months passed by and Amity got an idea. She had the idea to bring Luz back to life with her knowledge of abomination magic and technology. She brings Luz's body to her home as she hooked Luz with abomination goo to keep the body together as she used a heart that ran on steam to keep the body moving and pumping while the brain was a computer chip. Amity's plan works, but not in the way she wanted. Instead of bringing the Luz she knew back, she brought a new person, almost acting similarly to a child. Due to Amity being cooped up in her room and Luz's body being missing, she's seen as suspicious and Amity has to try and keep her creation hidden from everyone else. Will Amity be found out? Will "Luz" be forced to return to being a corpse?
