Amsonia

She joined after she Ran away from a doctor who had messed with her and made her underbelly a holder for liquid. He did this so he could smuggle poison into secure areas and slip it into others food by playing her belly off as a generic capsule gene. She was sent to kill Hyacinth, but he was nice to her and felt awful after poisoning him and rushed him to a doctor after Hyacinth killed the scientist. After being saved by Hyacinth, she felt as though she was in love, however she was just feeling gratitude for the first time. Refusing to believe she was wrong about Hyacinth, she had hatchlings with him, two got her “capsule” gene and one got a different kind of mutation giving him multiple eyes. Only one of her hatchlings seems to be “normal”, but she loves all of them even if she doesn’t truly love their father.
Currently works as a familiar caretaker, and can often be seen with a buttersnake wrapped around her arm or a dreameater trailing behind her obediently.
At first the poison in her belly would harm her too. Depending on the type, it would make her hallucinate, or fall down paralyzed. The effects lessened over time, but that wasn't because she built up a tolerance. The scientist just used lesser poisons in order to keep her healthy enough to do her task. This would usually result in the scientist having to finish the job himself. Amsonia, with those new feelings she mistook for love, immediately took him to a healer to save him too. That's why he felt like he couldn't exactly refuse her confession.
Full name is Amsonia Moruse
