"Leave this place" Emilia told Theia in a serious tone
Theia is still confused about this world because everything is happening so fast that she is getting no time to think straight and get everything arranged properly.
Theia took a deep breath, then she said "Okay, I am ready to leave the place, but before that,
Can you tell me just what are you?
I have never seen a white deer in my whole life, and that too is a speaking one.
Also, I am hearing various voices and seeing dreams where I see various monsters,
Then you are talking about me being a week or not ready to enter here, I am not understanding anything"
Emilia looked at Theia, She told her "You will understand it yourself as the time goes,
For now, your presence in this world is dangerous, not for this world or those monsters who live here, but for you.
Leave this place, I will contact you myself.
