Life, the universe, and everything

Midnight travels through it quite a bit during her stay in Ponyville. It is unclear whether she actually does spiritual travels or is just dreaming it. Both explanations hold their perks and disadvantages, (why does she dream of killing Twilight?) and I have no interest in revealing the secret right now. Basically, the Multiverse theory is what allows me to scavenge failed projects of mine into filler material for her, as well as picking up worlds I like particularly. On that note, Mirrodin is actually a mechanical plane, though I guess it'd fit if she popped in after the invasion. Magic: the Gathering, FYI.

Also, the Multiverse travels hold NO significance to the plot other than how she reacts to different stimuli. Just thought I'd get that out of the way.
