Im sure Im going to get flak for this, but who is MK?
MK is the spiffy fan-jargony name we use to refer to one of our favorite Elder Scrolls developers: Michael Kirkbride. MK was part of the Bethesda dev team, influencing most notably Redguard and Morrowind. He left the company before Morrowind was finished, but he still is revered and he still keeps in touch. MK's influence was a key shatterpoint in the Elder Scrolls' departure from a more cliche Tolkienesque D&D type setting to the more three-dimensional and deeply fascinating fantasy universe we got. His alien, esoteric artistic flavor and his florid prose molded the aesthetics of those two games, and with that he left his mark on the series. Many of the more seasoned lore buffs in the community regard him as the father of the complex mythology, mythopoeia and apotheosis that shapes the series so profoundly, and for good reason. Many in-game books were written by him personally (someone posted a list of them all a while back).
Kirkbride is most especially beloved on these forums for many reasons, one of which being that he keeps in touch with his fans. You can see him prancing about the forums under his new pseudonym
Merry Eyesore the Elk, spitting riddles and not having a care in the world. Not only that, but MK is the Lore community's number one source of renewable material for in-between game releases. While not officially employed by Bethesda any longer, they have paid him to do writing for Oblivion and its expansions, not sure about Skyrim. His most beloved works in this community, however, are his stories. Every now and then, when we have worn thin our anolysis of every in-game book, dialogue and meaningful glance we can squeeze from the latest installment of the Elder Scrolls series, jolly old MK posts one of his excellent http://www.imperial-library.info/content/michael-kirkbrides-texts (labeled Obscure Texts) for us to read, ruminate over, dissect and enjoy thoroughly. Just this past New Years Day, MK posted a great number of short stories that were really fun to read.
There has been controversy season unending over whether or not MK's independent works are "canon" (ignoring how little that word means in relation to the Elder Scrolls) and my answer to that eventual inquiry is this: Nothing in the Elder Scrolls is canon if you don't want it to be. Every history, every novel and account is colored by bias in this fantasy universe. It is up to you to interpret that information as you will. Ninety percent of the Elder Scrolls Lore is anolysis and interpretation, and there is very little fact one can shake a bug-armor-spear at. MK's works allow us to understand some of the finer nuances of the clockwork complexity of the Elder Scrolls universe from the perspective and knowledge of one of the chief designers of that complexity. I'm sure there are very few of us who take at face value the assertion that there is a colony of Khajiit living on one of the two moons, and that they balled up a lot of their hair to make a third. But in that weird-ass depiction of a half-reality, there are things we can glean, ideas we can refine and fun we can have.
It may have been smarter to end that answer after the first few sentences, but I hope the long answer can nip some of your later questions in the bud.
