Which came first: Oghma Infinium or Mysterium Xarxes?
There's gonna quite a few of my own tinfoil hat theories dotted throughout this opening post, so feel free to dispute. For the purpose of this brain fart, I intend to boil deities down to the base concept they represent.
Oghma Infinium: a compendium of all knowable knowledge created by Xarxes with information provided by Hermeus Mora.
Mysterium Xarxes: a compendium of profound and revelatory information compiled by Mehrunes Dagon.
Xarxes: God of records / death. Synonymous with Arkay and Tu'Wacca. Arkay preceded by Orkay; Malacath. Malacath = posthumous Trinimac (son of three).
Mehrunes Dagon: God of destruction, revolution, and change. Forged in the bowels of Lyg (previous kalpa?) by Meridia (once Et'Ada) who consorted with daedra (methinks Molag Bal). Meridia, the break of dawn, leads to Dagon, the dawn. Dagon revolts / destroys, leaving Lyg to Domination. Lots of cold chains, et cetera.
Xarxes is absent (name taken from long dead, revered Aldmer who represents / mantles the God of Records and Death perhaps?) but Arkay is present. At least one Altmer, priest of Arkay, believes Akray an uplifted mortal (Xarxes perhaps?), but Akay is an ancient concept and amongst the "first spirits". Perhaps absent and needs replacing? Uplifted by Mara (Meridia...?) This leads me back to Trinimac / Malacath. Overtones of the Missing God, but that's not surprising given that half the coin is the tails-side. Perhaps Dagon is to Trinimac what Arkay is to Xarxes?
Long ramble terminated. Mankar (mad but sincere) refers to the Mysterium Xarxes as "forfather to the wife of all enigma", that being the Oghma Infinium (Xarxes named his wife Oghma). Xarxes created Oghma. If both are nothing more than their respective books, then the Ohgma Infinium could be a transcribed copy of the Mysterium Xarxes (penned by the soul uplifted to become current Arkay). Is Dagon (or a previous form / associated concept) responsible for writing the record which became accessible by Mora (courtesy of his sphere) and thereby imparted upon the being who wrote the Oghma Infinium?
I expect no solid answer to this nonsense, and invite other nonsense to join it. I just want to know whether it was the chicken or the egg and why I can't take the damned burnt pages from the Museum of the Mythic Dawn!
