Oleander

Always appears to be sweet, bubbly, cheerful, and smiling. But don't trust her, she will turn her back on you for any reason she sees fit, including not feeling like putting in the effort to help you. She loves her plants and flowers especially, and 100% knows how to heal and poison someone with said plants and flowers. Likely sells herbal stuff to healers and mercenaries alike

She may pretend to be your friend if she believes that you have something that can benefit her

She is kind to others who like and do stuff with flowers, but it is unknown if it is because she genuinely likes them or if its to keep tabs on them and what they are doing with their business
