The warlocks wanted to stop her, but she ad warned them.
As much as they could easily drag her back and sit her down to explain the kind of transformation she would be undergoing in an hour's time, her warning was, to them, an order. And no one who openly defied and challenged the alpha queen ever lives to see the next day, warlock or werewolf, such as the gift and curse by the mood goddess to her people.
Rhian was many things, she was literally a lot of profanities that the world would use to describe a person like her, but there was one something she wasn't.
She was not a killer.
She would steal, she would beat up people who fought against her, but she never killed. She bever wanted to leave a child without a father or a mother. She knew first hand what being alone meant, and she never wanted to be the reason anyone was left without a family.
