Teaser of a future series written and made by me from MLP
 
Interpretation of the scene:
 
‘‘Everyone run and hide! There is something outside destroying the kingdom!’’ Before he could continue to warn of what was coming an explosion impact collides with the door causing the scared pony to shoot out and scream out of shock and fear, that loud explosion caused a strong wind current, because of what had just happened and the pony’s warnings now the guests panic. The princesses immediately took flight and leave the castle through the blast hole and notice how the entire kingdom is falling into chaos and destruction.
 
 
‘‘What is happening?’’ Celestia said, still shocked and trying to find the origin of this chaos.
 
 
‘‘Sister, up!’‘Luna pointed with her hoof at the figure of a Pony flying higher above them, Celestia immediately directs her gaze to the place where Luna is pointing and also sees the mysterious figure
 
 
‘‘Hey! Who are you?! Did you cause all this chaos?!’’ Celestia asked furiously demanding answers that unfortunately she did not have since the figure did not say a single word, which bothered Celestia more ‘‘You don’t want to talk eh?’’
 
 
‘‘Wait … I notice something in its appearance … it looks like it’s a …’’ Luna looks at the Pony well but she can’t distinguish it very well since it is right in the middle of the moon, but Celestia managed to notice something on the forehead of that I put something wide as if it were a stick stuck and I manage to draw a conclusion of what it was.
 
 
‘’It’s an Alicorn…’’ Celestia revealed.
