Hey, want to read a really, really great story? Of course you do.
Skywriter just uploaded his latest story, Lady Prismia and the Princess-Goddess. This story is part of his "Cadance of Cloudsdale" cycle, but one of the many special things about this story is that it is (I believe) the first fanfic of one of the official MLP novels by G.M. Berrow, namely, Twilight Sparkle and the Crystal Heart Spell. In that book, Ms. Berrow revealed the allegedly-canon backstory for Princess Cadance, including her childhood and how she came to be Princess Celestia's "niece," and an alicorn.
In "Princess-Goddess," Skywriter weaves the backstory provided in Ms. Berrow's novel into his own Cadance narrative, and fleshes out the exciting story of how "young" Cadance discovered her true purpose in the world. There are soul-sucking serpents, a musical mystical monastery, and a wicked witch!
Go read it!
