Original Description:
 
This fanart you see here was inspired by a fanfiction on FiMFiction called “Twilight Becomes A Dazzling” by Twilight Lightning. It’s an alternate story of what would have happened in Rainbow Rocks if the Dazzlings manipulated Princess Twilight into becoming a siren just like them. There was an aftermath story after this. But it wasn’t completed leaving it with a cliffhanger.
 
This fanart here was based on the end of the third chapter when the Dazzlings finally give Twilight their fourth pendant and in the end felt herself changing from a pony to a siren.
 
Note: I did have a few other fanarts based on the chapters of the story, haven’t gotten time to do them yet. So I did this one just for context. If you’d like me to do the others let me know.
 
The fanfiction can be found right here: Twilight Becomes a Dazzling - Fimfiction
