Princess Twilight Sparkle was having a day off. But that was before this strange mare showed up on her doorstep, telling fantastical stories about other universes and politely requesting impossible miracles of science. The Princess of Friendship is always willing to help a pony(?) in distress, though. And really, what better way to spend a day off than making new breakthroughs in the science of magical interdimensional gateway creation?
Of course, she didn't count on Discord's involvement, the scavenger hunt, or that particularly unpleasant portal problem that pops up as a result...
This is a tale that started out exploring the idea of what would happen if a human-in-Equestria story involved the human going straight to Twilight for help instead of wandering around aimlessly and fanboy/girling the whole time. It ended up involving Discord and possibly the fate of the universe. These things happen.
