The purple mist traveled through the air on their way to the city, corroding and burning everything in its path

After reaching the city, proceeded to go destroying buildings, also of filling the hearts of fear and desperation to the edge of madness

Feeling the pain of their people, the Princesses decided to use their magic to combat the threat, but rather than trying to expel the mist of the city, is increasingly towards stronger as if absorbing their powers

It was then that the mist swirled and took her true form, revealing her in the eyes of the princesses, which were stunned at the fact that she is causing such devastation and suffering to ponies

Luna: Twilight Sparkle

Celestia: What do you think you are doing?

Dimness Void: Since you two did not allow me to amend my mistake and break the spell, which pushed them to me, because then everyone will stay away from what makes them happy

Then she proceeded to attack the princesses with magic, immobilizing them and blocking their powers

Dimness Void: All will live in absolute dread and cry out for mercy, but I will not give any, because now I will rule, no more princesses, I’ll just be the Empress

Dimness Void: Now I will tear what everyone value most, I will end the day and night, from now neither sun or moon will rise again

Both princesses fell into a deep sleep while his powers were extinguished while the moon and the sun were eclipsed
