Не понимаю, как перевести "upon which that object fastens you". "от которой этот предмет удерживает тебя" или "к которой этот предмет ведёт тебя"?

В контексте:

“It is hardly something I hold pride in myself,” Whitemane said. She flexed her limbs and trotted slowly closer to the smaller pony. “And as a pony first and foremost, I apologize to you, my child. But, as a Queen, I have the safety of my royal subjects to be concerned with. I needed to know if the power that you carried was something that could threaten the populace of Verdestone.”

“And is it?” Rainbow Dash mumbled.

“You mean you don't know?” Whitemane stood before her and pointed towards the golden pendant around her neck. “You are not aware of the sheer precipice upon which that object fastens you?”

Rainbow Dash bit her lip. She brought a hoof up and lightly stroked circles around the ruby lightning bolt. She exhaled long and hard. “How...” She gazed up at Whitemane with soft eyes. “H-how much did you find out about me?”
