The Royal Prank

Rage suddenly rushed through Twilight as the shadowy figure disappeared with a teleportation spell, laughing in a piercing shriek as the ground below exploded with Twilight’s blast. Looking at the second next best option, she galloped towards Flash Sentry, eyes showing nothing but resentment towards this character.
“Um…Twilight…Hello…Got to Run!”
Flash ran away from the alicorn princess, too scared to use his wings as Twilight’s expression and the sharp stalagmites above made it impossible to fly without losing focus, Twilight following in hot pursuit.
“You Traitor! I trusted you! I befriended you! I liked…Erugh!” She shook her head and continued the chase, firing magical blasts behind his feet.

“Wait Twilight, its not what you think its liked!”
“You don’t deserve to explain anything!”
“What do you mean…?”
“Don’t “What do you mean” me mister! You and that pony were planning to attack all the alicorn princesses weren’t you?”
The blasts were getting closer to Flash Sentry as her anger increased.
“Wait, Twilight! I…”
Flash Sentry tripped over a rock and fell on the stone ground, leading to Twilight reaching him and using her hoof to hold him in place.
“Explain!”
“Rainbow Dash isn’t frozen! We never meant any harm! I’m sorry if we caused such a emotional trauma for you! I mean…we thought this was…”
“Just a prank. I’m sorry Twilight Sparkle.”
The shadowy figure stepped out into the light, leading Twilight to scream in surprise as the princess of the moon revealed herself, removing her disguise of Nightmare Moon that she had used so many Nightmare Night’s ago.

“Princess Luna?”
