1. There is clearly mass that act upon the world and has the world react back on it.
2. There is gravity as evident by jumping and arrows, although we don't currently know the force/mass ratio as of yet. I personally think that they are using approximately 9.8 m/s^2 for gravity in the TES games simply because that's what we are used to, however, for all we know it could be half or twice as strong as ours.
3. The magicka system is and intriguing one. The details are:
a. Our world is held together by what most people call the electrostatic force. I am inclined to believe that the TES universe lacks such a force.
b. When the sky was ripped apart by the escaping Aedra. Those tears in the sky are what allow magicka into Nirn. (The planet Tamriel is on)
c. Magicka allows people to expand their mental faculties and exploit their surroundings in a variety of ways including but not limited to: manipulating objects far away, manipulating the temperature of an area, reanimating dead corpses (I don't know how ghosts and spirits fit into this), manipulating the minds of others, and healing one's self or others.
d. I personally believe that lightning is in and of it's self a manifestation of pure magicka being released in some nearly uncontrolled form. I have come to this conclusion after having heard about the combat overhaul, and how while fire and frost damage are all fine and dandy, lighting spells now inflict mana damage as well as health damage. Look at it like it's shorting out someones mana supply.
e. Now this is pure speculation, but I'd be willing to bet that if someone from TES were to mysteriously make their way out of the sub-creation from whence they came, and into our creation, they would retain what magicka stores they currently have, but it would from then on out fail to recharge.
f. Apparently I stumbled onto a new element, where it says lightning in the above post, I originally made a typo and put lighting. You can tell the difference, and now perhaps it makes more sense, I'm going to have to contemplate how light works into this for a bit and get back to it. -- After a little bit of thought, I've come to the conclusion that the Ayleids may be correct. It's rather complex, but if magicka was actually a replacement for the electrostatic force which is essentially an extension of the electromagnetic spectrum, then it is what binds all matter together. This force that magicka exerts on everything, it in it's purest form, may be white light. If this is true, it could explain a variety of religious influences for the Nine, among other things. It would also hold to explain more about Tamriel in general, but once again I must give it more thought.
4. The types of rocks and minerals in TES are considerable different. We can note that Ebony and Glass are in fact types of ores that are mined out of the Red Mountain. Whether or not these ores are structurally similar to Ebony (a hardwood) and Glass (melted sand... basically) is undetermined. I personally believe they just ended up with a name that is used in other ways. In light of this, we have to ask ourselves: "In the TES series of games, is there any type of tree that also creates Ebony?" It may also be of interest to note that the windows used in pretty much all of the buildings in Morrowind and Oblivion are, at least I think, made out of glass. I personally don't think that one mountain could fuel the worlds needs for such a vast quantity of ore.
Tell me what you think about this, what I call "super anolysis". Any ideas or feedback would be great.
Thanks Velorien for correcting me, It's been a while since I read through the creation story of TES.
