I hope this works.
This is what I've come up with so far (as far as DS1...DS2 might change it with additional information). The world of Dark Souls exists within 3 Physical Planes, as well as 1 Mutable Plane, those being (in no particular order, even though I'm numbering them):
Physical Plane 1: The Material Plane. This is where Humans exist after the war with the Dragons and the Age of Fire has commenced. It is, in my opinion, of the following properties:
It has Earth-like gravity.
It is mutable only through physical manipulation (i.e. you can only make a sword with the proper materials, such as steel or iron, but not out of nothing).
Magic exists but cannot change the physical attributes (i.e. lead cannot be turned to gold).
Physical Plane 2: Kiln of the First Flame. This is where souls were forged for the undead. Four of which were Lord Souls, made for those with enough power/ambition to wield them and usher in the Age of Fire. 3 were made to bring about the AoF, and 1 was the precursor to the next Age, which is, of course, the Dark Soul. It is of the following properties:
It has Earth-like gravity.
It is physical, as well as, magically mutable. This can be seen in the fact that when Gwyn linked the flame the power released was enough to melt the environment and render most of the plane to ash. It is magically mutable in that it was most likely the first origination of mankind's souls.
In my opinion, the magical nature of the Plane would allow magical mutation of elements, given that the wielder had proper experience and power.
Physical Plane 3: The Abyss. This Plane is somewhat a dichotomy in its attributes. It exists as a shadow to other two Planes. Its existence is completely necessary as light cannot exist without darkness. Thus the disparity. It is possible that when the Age of Ancients was in progress, the Material Plane was dominant, repressing the other two planes allowing them to mature. It has the following properties (from what I can figure):
It has an Earth-like gravity, however, it is subjective to the being that is observing it. With proper training and/or transcendence of it is possible to change the nature of the Abyss.
It is completely mutable in that only itself can be manipulated. For example, a material from one of the other two Planes could not be changed by the Abyss, but an object OF the Abyss COULD BE.
It is, as well as, is not, magical. This is why the Abyss is dichotomous, to me, it is that which comes before. The magic does not exist, but the potential for it does. If one can manipulate the potential, they could create whatever they needed.
Mutable Plane 1: Time. I hesitate to call this a Plane. It may be that it is merely a Dimension. It acts in every way as we understand it. EXCEPT, as Solaire explains, in Lordran, where it flows differently. What makes me think it is a Plane though, is that it works on the others, creating what could be considered bends, allowing heroes of one time to enter the time of others. I believe that time is what I would consider a PURE Plane in that it simply IS. One cannot reside outside of it but, as we see with the DLC, it can be manipulated with intent. Which is how Manus grabs the PC and drags him/her to Oolacile past. It has no attributes that I can think of, rather it can only be described as a still lake rather than the more common "river" since one can go backward or forward.
