Leila did not spend any more time necessary after taking care of the beast problem. She once again let out her clone to replace her in making sure no one will doubt her presence in the mountain. There is a place she should be other than here.
Though suppose she is to stay here because her followers need her here. But she is confident enough that her clone can do the job itself without her. So she left the place and teleported to Lake Laura as she had promised the last time she came there.
There were almost changes there as far as her eyes could see. As she has already told the creatures living here of her presence in advance, they did not place much importance on her when she suddenly appeared out of nowhere.
