Am I getting the concept of entropy wrong or is it Obsidian?
So, there is a "God of entropy". Entropy is a measure of disorganisation, of possibility, in simple terms - measure of chaos inside a system. So, a god of entropy who wants to "end all things", to make everything still in absolute zero, is pretty much the opposite of entropy. He seems as strange as a god of war who dreams of ending all wars and getting eternal absolute peace.
Shouldn't the god of entropy be the opposite, more like Joker, who wishes things to happen in the most chaotic and destructive way?
If I get the concept of entropy right, then Hylea with her "experience everything, invent new, change things" motto is way more entropic in nature then Rymrgand.
I mean, the state of the world desired by Rymrgand seems to be the state of ZERO entropy.
If we have a cup of coffee and a cup of milk sitting on a desk, the god of entropy should wish to mix them, to get the chaos of them mixing, not to freeze them both and sit and enjoy nothing happening. A god who wishes to stop every process in the universe is a god who is AGAINST entropy, isn't he?
I'm not willing to criticize, more to get the idea before DLC releases. Of course, there is always the ultimate answer "a god is beyond your comprehension"
The link between thermodynamic entropy and disorder is kinda tricky (or at least I find it so). As I understand it (which is probably quite poorly), we can measure certain macroscopic properties of a thermodynamic system* like it's temperature, pressure, volume etc., and these tell us something about the microstate of that system (the exact locations and velocities of all individual particles making it up), but obviously not everything. Entropy is a measure of how much we don't know know the microstate of a system, given the knowledge of it's macrostate, so the higher the entropy of a system, the more information we'd need to fully understand it's microstate. It's for this reason it's often described as a measure of disorder of the system, and it turns out that the highest entropy state of the Universe would be what's often described as its heat death: a state where all matter is at the same temperature (though this isn't an entirely accurate description, it's close enough).
It's clear (to me at least) that this is the idea Obsidian had in mind when talking about soul entropy. In this case a low entropy "soul system" would be one including lots of concentrated strong souls, and a high entropy system would be one with lots of what obsidian called soul motes (little bits of souls that have come loose during the natural process of the wheel).
It seems that Rymrgand is the god of all entropy in Eora (thermodynamic, soul and, presumably, information entropy). So he'd like to see them all maximised.
Hope this was at least somewhat helpful.
