Because COLORING!!

Okay, well The Dresden Fillies is a trilogy of fics. It starts off with Strange Friends, which opens with Harry fleeing from monsters in the Nevernever. He randomly opens up a rift to escape, and ends up in Equestria. He meets the Mane Six, but then Spike gets kidnapped and he helps them find him. Adventures ensue.Whenever the story is told from Harry's perspective, it uses the traditional Dresden Files first-person narration, and it is done so incredibly well that you'd swear Jim Butcher himself is writing it.He later goes back to visit in the second fic, False Masks, and this time he brings Bob with him. ^_The final fic in the trilogy, Great Power, is currently ongoing.
