Universe E

Universe E is one of the universes in the collargogglebirdhorseverse. Universe E is principally based on the universe established in the television show My Little Pony: Friendship Is Magic and its supporting media, and (for the most part) follows the rules of that universe, including:

• Only ungulates and mythological species are sapient.
• Ungulates maintain a non-anthropomorphic anatomy.
• Magic is commonplace and intrinsic to many species, although only unicorns and alicorns may manipulate it freely.
• Technology is present but has not developed to industrial levels (with some exceptions).

Timelines

Many individual stories take place in Universe E, some of which have irreversible or world-ending consequences. To allow for several stories to exist in the universe without conflicting continuities, many stories take place in self-contained timelines.
