It's a big multiverse out there, so of course there are going to be some stories that have nothing to do with ponies and thus cannot be on fimfiction (sad). Luckily, we have this forum here! Post any links to non-pony side stories you want here, those I approve will be compounded onto this post in later edits. (The list has shrunk because many of them were moved into Enchorus.)

PRIMARY SIDE STORIES

The MORI Corporation
A story of a corporation plugging away at a multiversal superstructure. Use Spacebattles' threadmark arrows to navigate

Wanderers
The adventures of Vriska and the Doctor (includes some stuff that isn't in Enchorus yet)

In an area of the multiverse called the Prism, things are not as they seem.
