When I think about the events that happened in Oblivion, I think about Gaiar Alata. The so called "Paradise" by some is a place that was created, as it seems, by the owner of the book Mysterium Xarxes, at that time, Mankar Camoran. What are your points of view on Gaiar Alata?
Is a realm created by a mortal related to any Daedric Prince, if that same Prince showed the secrets of creation to that same mortal, or the mortal that creates the plane achieves Godhood or at least Immortality through the creation of his/her own plane?
Is Mankar Camoran the first to create Gaiar Alata or is it possible that others through time after Xarxes have created their own? And the plane created is always a Paradise or the creator can choose what he is creating?
As a notable fact, the knowledge within the Book Mysterium Xarxes comes from Xarxes (the Scribe of Auri-El) who wrote the Book Oghma Infinium. But the knowledge received by Xarxes was given to Him by Hermaeus Mora.
Another question must be made here: Is it possible to create a plane using the Oghma, since that book is the reference used to write the Mysterium?
Its possible that Mankar created Gaiar Alata, and that that power was given to him by Dagon. That being said it is evident that Dagon ether Did not create his own realm (or anything for that matter seeing as how he is Deadric) or did so when he was at some point an Aedra.
Him givng Mankar the power to create makes sense for two possible reasons- 1 The deadra have a profound ability to change the Aedra's creation(ie Mankar Camoran); 2 Mankar like all mer is a decendant of the Aedra (Breton = Ayleid).
The Daedric Realms were formed on much the same principle: padomaic powers using aetherial refuse to build their void-territories. The Towers built on the Mundus, since the lands around them congealed in the absence of the gods, were unable to match the capriciousness of the Lords of Misrule. ~Nu-Mantia Intercept
The basic principle is rather simple. Collect magicka, dump it in the void and create a realm.
For the edification and admonition of all that should pass through this hall. Know that this is one of the five great Anchors that moor the Battlespire in its place and retain it in the life-flood of sustaining Mana, without which there is no light, no life, no Being. ~Anchor Warning
Though they're not very explicit you can find similarities in how the Battlespire stays up.
So anybody can create a realm provided they can provide the magic to sustain it. Providing the magic seems to be the major problem. Not sure where Mankar got his from. Perhaps Dagon was loaning him some.
Isn't Mankar just a bundle of secrets.
This could just be a personal delusion but, there apears to be a very important separation of change and creation in the TES universe.
Bare in mind in this world (the real one that we are in) there is no creation that is not change; the matter in my body as well as my computer and all its involved peripherals are animating(changing) as I type this comment; the computer itself was changed from various forms of matter and, is a conduit for light and electricity which also are having there animation changed, the idea to make computers was a matter of changed animation inside the minds of the creators.
I believe Creation exists in the TES universe just the same as in this one; an abstract incomprehensible concept of divine intervention, which ties rather well to being a trait solely belonging the dead gods(Aedra)
That is what people take away from On Aedra and Deadra. If you look at all the other sources rather then being (in)capable of creation the difference between Aedra and Daedra is simply that of those who created Mundus and who didn't. Were it not for Lorkahns trickery or planning none of the et'Ada would have broken the status quo that existed at the time.
