Twilight Sparkle and Sunset Shimmer are tracking down a dangerous criminal through dimensions. Just how far is Twilight willing to go to stop him?
Based on Sunlight Sliders and Novel-Idea's And a Sky full of Stars. Contains mild spoilers. Can count as an unofficial prequel to the latter. Yet the story is self-contained.
The original version is in Chinese and can be found here. The link goes to a page where both Chinese version and English version are provided but you can navigate to the Chinese only version if you know how to use fimtale.
