Progress

Progress is a comedic fan-fiction written by Andrew J Talon, with derivative works by other authors and artists. They can all be found on Equestria Daily. It is one of the earliest and most influential Luna-centric fictions and runs on social awkwardness and run-away imaginations.

Plot
Each story or chapter is titled Luna vs. 'X', with 'X' being the object or concept that is giving Luna trouble. The first story involves Luna attempting to discern the purpose and operation of the castle's microwave while stubbornly refusing to ask for help. In the process, she acquires an abacus that eventually becomes something resembling a pet or stuffed animal to Luna, since it is a relic from her pre-banishment life that she actually knows how to operate. The second story has Celestia sending Luna to attend a baseball game with the Apple family, in disguise of course. The third story spans three chapters and tells of Luna's "assignment" by Celestia to move in with Luna's attendant Sundance and her boyfriend Hoyden -- who basically works as a crash-test dummy for an explosives company -- to better understand Earth Ponies and how the normal population lives.

Luna
Adorkable in the extreme. She wants so badly to fit in to modern Equestria, but has a tendency to babble when she gets nervous. Gradually she learns about technology, sports, and other facts of life. Her imagination has a way of running away with her when things start to get awkward. She often disguises herself as an earth pony or unicorn named Selene, but that disguise is rarely able to stand up for very long, especially around ponies who know the Princess.

Sundance
Whether through fear of losing her job or nearly infinite patience, Sundance is always ready to assure Luna that nothing is wrong and that her latest fauz pas isn't the end of the world.
