Elise didn't know that the mirror could move. They could sense movements of the living but not the dead. She wasn't aware of the Hellie Mirror's movements until she was pulled inside by the mirror. The different or the air told her that she had shifted into a different place. Realizing it, Elise couldn't help but find herself looking at the velvet sky which was colored deep in the pitch black color. There was no star on the sky neither was the stars.
The sky was empty and void, only having tinge of red all around them as if below the sky was a heavy sea of burning red flames.
Elise then felt the force of wind blowing her hair upwards, realizing she had fallen from the sky and was free falling down to the ground. The wind caused her to close her eyes.
She was falling! Did Orias think she has wings?!
