Hey. My name is Melodious Crescendo. I used to a semi plain unicorn. Now I’m an siren-alicorn hybrid with the power of a unicorn ( Biologically ascended but not a Princess ) in another dimension living with Sunset Shimmer. Here’s how that happened and some more after that.

References to MANY other fics. Most of the credit goes to the Rulesverse and the Dead by Sunset stories.
