A slightly nerdier different take on Friendship is Magic.
Nightmare Moon has returned.
Now, a band of misfits must join together against with the Elements of Harmony to save Equestria from the greatest threat they've ever encountered!
It has action! It has drama! It has slapstick humor out the wazoo!
It even has a couple of wazoos, too!
It's the story Gotham needs, but not the story it wants; it's Pathfinder... with ponies!
(Based off of an actual Pathfinder campaign. I cannot begin to describe just how awesome it was without writing an entire story about it. WHICH IS AWFULLY COINCIDENTAL.)
