She took a deep breath before finally continuing to walk to the throne room.
People's support was quite expensive. It does not come for free.
But, once she had done her part, she would be assured that she had their support as long as they still benefited from her. This was something she learned in her past life.
They might betray her at some point, but only if something or someone offers more use, benefit, or value than she does.
Thus, Arabella needed to be as useful, beneficial, and valuable to them as possible to maintain their support.
She recalled the time she was standing by the window of the Magic Tower. Her allies back then betrayed her and came to kill her. And she understood now that she was betrayed because her use was done. She was their way into the securely guarded capital and when that was done, she was set to be disposed of.
