DAHLIA is a manipulative woman who likes to take control over every situation. Whether that's be emotionally manipulating them, taking away other's needs or acting on their sexual desires, she will get what she wants and rip at your soul at the end of it. When she doesn't have control, she loses her temper and seeks to blame everyone else but herself. 

Her voice is husky and honeyed as if she never means a single word she says. She's got a noticeable posh British accent which gives her this air of maturity.
