So many questions indeed, I will give them a shot here. So as I pray, Wall of Text.
abscess wrote:I don't remember if this has already been asked but, how big can a Reality Marble be? I mean, Archer and Shirou release something that grabs everyone in a vicinity and transports them into his little pocket world, but how big is that pocket world of his? World size? Just some kms?
I do not believe it is exactly a pocket world. In fact, I think both the user and the victims are still on Earth. Picture this, the reality surrounding you is just made of
playdough, and it can be molded by something called "Order". Your usual surrounding is the way it is because the "playdough" is being shaped by Gaian Order. The user of a reality marble is able to alter/overwrite this Order, thus shaping the "playdough" to his wishes. As the environment conforms to this new order projected by the magus, the reality marble becomes materialized. Because of this, I think the size of the reality marble will depend on the user's ability, such as experience, magical affinity, and most importantly, prana. So, what I am hypothesizing is that, if you run far enough in a reality marble, you can see a boundtry between the reality marble and the unaffected world. This is hinted in the ORT entry. As the reality marble Crystal Valley is described as ORT's lair, which means that it has
boundaries.
For the next question, let's suppose that it grabs people in around a 10 meter radius (I'm just making up number so don't take anything specific here), what happens to the 10 meter radius in the real world? It just keeps on going unchanged?
This sort of falls back to the previous question. The 10 meter radius of space is still
there. This 10 meter radius of space exists to conform to an order. If the Gaian Order is dominant, it is just a regular piece of land. If, let's say, ORT's Mercurian Order is dominant, it becomes part of his crystal valley. You can say the land/environment is blank, you may paint it anyway you like through "Order".

How does space work with the world and a reality marble? UBW is described as an "endless" plain of swords, yet if it was a 1:1 space ratio that would mean technically the world is enveloped in UBW, which obviously isn't the case. So from that, I assume space in RM=\=space in real world. Especially since when shirou used it against gil, rin/saber didn't enter it, and they weren't too far away. But then, what happens when you move around inside UBW? Lets say you enter UBW, run 10km one way, then dispel it. Where would you be in the real world?
This is the original quote from the UBW route:
UBW route: Last Fight wrote:Our[Shirou and Gilgamesh] voices overlap. The change happens in an instant. The light coming from the lake eliminates the hill of swords. A great magical energy has smashed away the already-disappearing Reality Marble.
There are two things to notice here. First of all, since the passage is narrated in first person, this suggests that Shirou can
see the lake from the Reality Marble, that mean it is
not endless. Secondly, the reality marble fades
gradually (possibly in the fashion of a shrinking circle), which may be due to Shirou's dwindling mana. I think both of these points back up my theory. They also answer your question: Reality Marble space = real world space. So if you enter UBW, run 10km one way, then dispel it, you will be 10km from where you started in real world. HOWEVER, AND THIS IS VERY IMPORTANT, UBW does not seem to bend the laws of space. So if someone's reality marble does bend space, and I know there are indeed such ones, I am not sure where exactly you would end up at.
And, a further question. What does a RM look like to someone in the real world? A barrier of fire (in the case of UBW)? Nothing? Could someone "walk" into a RM thats been set up?
From all the sources I have come across, it seems you can just walk into a reality marble.
And finally...doesn't Nrvnqsr state that the Soil of Genesis is a) a reality marble comprised of over 500 of his parts and b) taught to him by the Serpent. Whats more, he uses it to restrain Arc, so its properties are nothing like UBW.
Soil of Genesis is a whole thing by itself, it is a great spell from the Age of Gods, long thought lost. You can consider the Soil of Genesis as an
application of Nero's reality marble.
@Gumaster: Those are some hardcore questions. They actually prompted me to re-read a lot of stuff. I hope I am conveying to you a clear idea.
