Author's Note: You may have noticed that I made up several words and concepts over the course of the story. I supplied definitions and explanations on fanfiction.net, but neglected to do so here. I thought I should rectify that. Each entry has a parenthetical amendment indicating where it's first used.

Inventions:
Cesium dragon: Mightiest of the little-known alkali metallic dragons. Famous among dracologists for its fire breath, which burns faster than the speed of entropy. Normally, this wouldn't even make sense, but dragonbreath, like dragons, is magical enough to make it work anyway. What this means is that the information of an object incinerated by cesium dragonbreath is preserved even though the object itself is not. Through the proper rituals of magiquantum entanglement, this can turn a cesium dragon into an instantaneous delivery system.
Note: Unlike many of their lesser cousins, most notably the sodium dragon, cesium dragons neither burst into flame nor explode when exposed to water. Please bear this in mind when attempting to slay one. (Chapter 8)
The Cloppler Effect: Identical to the Doppler Effect, the phenomenon where motion relative to the source of a sound makes that sound change in apparent frequency. (Chapter 14)
KLOP Radio: Radio Free Ponyville, home of DJ Pon3 and MC <3. (Chapter 14)
Muffylactery (MUH-phil-ack-tur-ee) n. A unique variant of magical prosthesis for the Equestrian pony (Equunculus filia) designed to replicate the flexible, spell-form magic of the unicorn subspecies in the others, who are normally limited to innate abilities. Similar in both functionality and design to the magic wands of several universes, these prostheses are generally composed of a core material with high thaumic capacitance encased in a magical semiconductor, usually a stable organic material such as wood. Each individual soul must be matched to a specific core/casing combination for optimal performance. Most such prostheses are modeled in the form of unicorn horns, but studies suggest that the shape of the casing can be as important as its composition, if not more so. Because of several commonly required core materials' exceeding rarity (sphinx hair), expense (stabilized rainbow), and/or inherent danger (cockatrice feather), they are more hypothetical applications of magic theory and curiosities of the rich than common items.
Ditzy Doo's muffylactery is self-made. The casing is composed of Zendikar hedron stone, noted for its high magic capacitance. The core's composition is unknown, as is who taught her how to make the device. (Chapter 1)
Postal abbreviations: CA - Califoalnia, CS - Cantershire, NY - New Yoke (Chapter 19)
Ramen feedbag: An application of one-use spell seals, in which a specific spell is coded to be cast upon the seal's destruction. In this case, the seal acts as a separating partition between two chambers of a disposable plastic nosebag. One side contains instant oats and dried seasonings, while the other holds water. Pulling the strap on the top of the container not only allows it the be slipped over the muzzle for a hand-free meal, but breaks the seal, mixing the wet and dry components and casting a weak heat generation spell. The end result is something resembling oatmeal. Cheap, easy, and very popular amongst college students. (Chapter 5)
Speedy Service: (5436-5509) The daughter of a restauranteur, she discovered her talent for communication at a young age and revolutionized the magical discipline of telepathy. Her work continues to be the foundation of most modern communication spells, including the silent tactical network of the Royal Mageguard. Sadly, vague and spotty records from the time have resulted in an ongoing debate amongst historians as to which of as many as five different unicorns was really Speedy Service. (Chapter 13)
Temporal omnipresence: The ability to perceive time from an objective, nonlinear perspective, a.k.a. being in two times at the same place. Or different places. Or more than two times. (Chapter 16)
