I know, right? But it would have done much better in the hands of a writer who understood the show-don't-tell rule. Speaking of which, I implore everyone on this thread to get an eyeful of https://unicornjelly.com/index.html and http://www.jenniverse.com/

And thus we name our new cosmos Lamdaar! The next will be of a complicated nature - because it is not easy to picture more dimensions I'll ask future posters if we should have three spatial dimensions and one temporal dimension, or go for another amount for either, but not without discussing how that would work first.

>>71789540

And everything physical exists by sliding and latching onto the latticework grid. The perception of left and right and are an illusion caused by the curvature of both temporal dimensions,

They're unfortunately not very adventure-friendly settings that would keep a D&D party occupied very long unless they're the type that can tolerate lengthy screeds about alt-physics. And sword-and-sorcery is a very difficult genre to explain this kind of stuff.
>>71789707
I'll take that as a no, then.

Like Mundis Mundis, Khex Lamdaar has three spatial dimensions and one temporal one. Very convenient for travelers who hail from ours! So far we are: Khex Lamdaar D(4)

Next off we have something more tangible - Hyperdimensional Geometry. For instance, Mundis Mundis is expanding and infinite. It was created from a big bang, and is getting colder and larger. It is fated for heat death. This means it is changing-state and unbounded.

Whereas Tryslmaistan always was and will forever be. This means it is steady-state. No matter what happens to its its laws of physics are averse to entropy which means even after catastrophes like the cataclysm, give it enough time and it will return to its original state.

(From the Gorbald page and Pastel Defender Heliotrope there are many more than just this but I cannot decipher what these abbreviations mean)

> (ss): Steady state
> (fb) Finite bounded
> (Cy) ???
> (E) ???
> (Or) ???
> (As) ???
> (iu) ???
> (Fb) Mispelling of (fb)?

So i'll just make another from the final example we have left - the universe of Aeryx Pastel, where everything originates from a single point and is returns back to where it was after being vaporized at the end of the universe.

For the first step, roll 1d3 to determine if it is a steady-state, unidirectional expanding-state, or omnidirectional expanding-state universe.

Khex Lamdaar is unidirectional expanding-state, in a similar manner to Khex Pastel. For the next half of hyperdimensional geometry, let's roll a 1d3 to decide if it is:

> Horizontally Infinite (There is no end to the world regardless of how far you walk. But there's only one layer of air and one layer of earth, both infinitely deep)
> Vertically Infinite (Infinite layers, all different)
> Horizontally Finite-bounded (Go far enough in one direction and you'll end up back the other end. It constantly repeats over, and over, and over again.)
> Vertically Finite-bounded (Fly high enough and you'll find the bottom of the layer you flew from. There is only one layer)
> Finite-unbounded (The end of the world is spatial.)
> Write-In

The world consists of finite 'pockets' that fold and unfold in response to the cyclic empty/chunky turbulence as it trickles down, sideways, and down and sideways again indefinitely. The universe is in a staircase shape and each step has its own 'pockets' but traveling from one 'step' to another requires an enormous amount of force going upward/downward and backward/forward depending, to surmount the horizontal line of the 'step'. The space between 'pockets' is a vast expanse of empty, whereas the 'pockets' are hollow lumps of chunky that slowly contract and expand as the surrounding empty flows in and is pushed out again.

As time passes on in Lamdaar, it fluctuates between being a "chunky" or "empty" period. The space between a shift in these qualities is called a phrasce ("fraish"). At the start of a phasce roll for:

Roll 1d3 - 2 (so 1 means -1, 2 is 0, and 3 is +1) and change your place on the chart by it. At game start it's assumed to be 5.
At 12 and higher the "chunky" force is too powerful for humans and similar organisms to survive, if colonies of them exist on Lamdaar they need to closely monitor chunky forces and head to cryostasis before the start of another phrasce.

The world is a grid-shaped latticework and upward, downward, forward, and backward apply context to movement. Left and right are impossible, but the perception is formed by the never-ending interactions of empty and chunky loosening/bending the grid respectively. At least those are my thoughts on it, in a way it's more two-dimensional mimicking a three-dimensional existence on a specific four-faceted frame with the abstract density meta hastening/slowing the passage of of time.

Here's an extremely crude MS paint diagram of what I'm talking about. Say the blue and red circles are an adventurer and a bandit, and the adventurer shoots an arrow (brown line) at the bandit, the arrow doesn't fly through the air to strike the bandit, it goes downward, then forward to hit/miss the bandit as they go upward/downward to dodge/fall into the arrow, respectively. There is no sense of left/right, everything takes place on the grid, and the only reason for the sense of broad perception is the warping of the grid that the empty/chunky applies. Maybe this means the more or less empty/chunky there is, the more or less 3D the world seems, maybe chunky refers to density of memetic information weighing down the grid whereas empty is its absence?

Next up is the Entropy Factor. The higher it is, the more it puts Lamdaar at risk of heat death. It is the rate of chaos, the dissolution of forms and how likely things are to break down and spread out. It is the rate of ergometric change, or the measure of physical outcome compared to the effort put into it. Entropy is also the loss of information, whereas anentropy is the restoration of it.

Entropy can come from various sources. Drop a cup on low-entropy Tryslmaistan near a veil and the anentropic energy will repair it. This is because the amount of entropy in that universe has remained the same since the beginning of time. Do the same on an extropic universe and it will detonate and burn your face off, for every action done adds to the universe's net entropy. But drop your crockery on Earth and it will be broken and produce a noise that will be forever consumed by the cold, cruel universe of Mundis where the entropy decreases indefinitely until heat-death.

There's no conflict, here. He rolled for step quantity and I rolled for step size. What's really at a conflict is whether or not the time shifts randomly or cyclically, though I'll explain my reconciliation after rolling on my own table.

>>71797139
I wasn't thinking of it as a 'visibly' flat piece of paper, more that it's fundamentally flat and the distortion of empty/chunky is what gives the world depth. On the surface, it might seem vaguely three-dimensional but the physics are completely at odds with the idea of wide space as opposed to a flat grid. That's mostly only to permit not actually three-dimensional '3D' environments; dungeons, forests, and so on. If that makes any sense.

>>71797188
>Greg Egan's Orthogonal
I've honestly never heard of that but it's very interesting. Curious to see that the world is low entropy. That's probably why it's so huge come to think of it. I'm eager to see what you have in mind.

Of course this is all a group project, I want to hear your ideas about how we can improve on the grid physics or build on the empty as opposed to chunky/time flux dichotomy.

>>71797266
1: Pockets appear to be a solid object like our own planets, phrasces are caused by their analogue of earthquakes.
2: Multiple "planets" orbit the complex centers of the planets. Fluctuating force fields (in the original scientific context) may cause the phrasce cycle as worlds bob into different locations.
3: Up to someone else.
So there's by itself length and depth, but not width. What causes width to occur is the chunky factor, of course. The deeper you go into a pocket, the more spacious it gets until it starts looking like proper khex. Maybe it gets up to 4 or even 6 dimensions when you're deep enough. I imagine that it looks like one of those charts used to explain gravity fields except that a second one is piled on top of the first. However, the player zone is still in 3.something space, except that a residential place's location is not exactly stable, it will shift over a relatively small amount of time (in geological terms).

When I made this thread I had never expected anyone as beyond-thinking as you to participate here, although sadly all this talk might scare off any future posters, for better or for worse. Our interpretations of this setting are probably as varied as our approaches to structuring it.

Anyhow, the entropy is low. It occurs at a much slower pace than it does on Mundis Mundis. Under natural circumstances, if this universe is left alone it will never be under threat of heat death.

I'm thinking the inside of the pockets are a sort of 'macro-pocket' dimension insulated from the empty outside, with a series of interlocking orbital fields going from the outermost portion to the innermost, while 'planets' periodically shift from one orbit to the next, eventually running the entire gamut. Here's another rough MS paint diagram of what I'm talking about.

>>71797632
I'm thinking the 'planets' get more chunky the deeper into the pocket they go, gaining substance and getting larger but gravity doesn't exist so the difference is largely in the recursive amount of territory on the 'planet.' Somewhat related to that, as the 'planets' drift back to the front and lose substance, growing smaller, the loss is jettisoned outward, producing the expanding effect of the pocket, and the contraction as it drifts inward and absorbs the chunky.

>>71797581
So far the physics seem to have internally consistent logic, it's just that it varies depending on how much empty and how much chunky is present in the ambient environment which I think is great, it gives GMs a lot of breathing room for versatility.

>>71797600
I'm not surprised that there's high magic, I'd be somewhat shocked if there wasn't, given that the lack of entropy leaves would-be magic users free from the laws of thermodynamics.

That's a good idea, Checkerpiece too. To expand on the depth idea, what if the closer they are to the empty the smoother their surface is, but the further into the chunky they go, the more jagged they get, ranging from perfectly smooth to sprawling labyrinths? I'll go ahead and write out 1d6 or so atomic laws, there's not necessarily any need to adhere to the system we're used to, especially with how potent and present magic is.

>>71797906
Something with a "handle" theme would be cool. I thought of the chunky cores as being infinitely long cyclinders.

>>71798025
>(a)tomic
Instead of protons, neutrons, and electrons coalescing into atoms, there are pieces of chunky, or chunks, floating in the empty, or emp-field, short for empty-field or empirical-field. The empty is constantly trying to push out the chunky and the chunky responds likewise, but where the force the empty exerts to push the chunky stays constant, the force the chunky emanates grows exponentially the more chunky there is in the ambient environment. That's why lifeforms can tolerate the empty but excessive amounts of chunky are lethal, quantities of force they can't resist comes at them from angles they aren't capable of comprehending.

As opposed to the empty, which seeks to remain static, the chunky force pulls itself together, so the chunks inevitably form into clumps, which differ from one another not in their proportions, as atoms do, but in their texture, forming a mass of like unto like. These clumps can be converted into different kinds of clumps by certain reactions, which are vibrations that slowly carve into and change the texture, For example, setting a pile of logs on fire introduces a vibration that converts the wood clumps into heat and smoke clumps, which are subsets of energy and vapor, two of several broad archetypes of closely related textures.

>>71798197
Everything that has substance is another form of clump, which is itself a collection of chunks, or infinitesimal bits of chunky drifting on the grid. If too much chunky is in a single area, the chunky force causes the grid to 'bend' or 'curve', producing angles that would be impossible otherwise. Empty is the natural state of the world, chunky is an imposition on it that sustains itself in pockets, where the empty pushed pieces of spontaneously spawning chunky together. When too much chunky appears on a step for the empty to push them into manifesting pockets without crowding, the chunky is sent down to the next step, where the empty begins pushing them together, forming a new set of pockets and repeating the cycle. This implies that the stairwell was always infinite and always existed, but there are a finite and linearly but endlessly expanding number of 'pocketed' steps. It comes to me that I'm mostly rambling and haven't grouped any of my thoughts into coherent laws as I specified I would but the question of where to start is incredibly intricate to work on only a few hours before dawn, I should probably go to sleep and re-approach the concept when I come to.

>>71798197
>>71798270
Ehh, not really into the idea of chunkiness instead of energy being the fundamental substance of matter.
Universal scale-Decompassation
Decompassation is the forcing of additional directions into space as "chunky" intersects with empty. The increasing amounts of false-direction over true-direction are analogous to gravitational pull, as more entropy can potentially exist inside a chunky zone. The additional effect of this that gets "chunky" its name is that the interaction between these forces causes organic substances to more easily cohere and stick to each other, unpleasant for extraversal biochemistry. Native creatures have workarounds to this problem.

Okay I'm kicking this thread back up.

Halfway universes are a thing. See pastel.
Universes can transition from one class to another as well. If this diagram is to be trusted, Pastel used to be a Khex universe, and early Mundis Mundis would've been considered an Aeryx class world.

Yeah they're not exactly strongly different. You can easily have an Aeryx Khex.

>>71797632
I'd love to elaborate on this concept but the explanation is not hitting me well. Please reparse or elaborate further.

At the edge of every pocket is a nebular ring of radiation that has been compressed from a radiant into a fluidic form by the emptiness. When this ring is sufficiently massive the innermost regions regain cohesive properties and precipitate back into the center of the pocket. This natural event reduces entropy within the pocket.

Some radiation still escapes the ring, where it becomes fractured into a cross shape. The intersections between radioactive crosses of the ladder are poorly understood, but known to create particles that sometimes reflect back to the ladder and react with the nebular rings.

The most extreme chunky states are the scrolls, infinitely tall and massive centers of the universe. By themselves they're completely black (a necessity to prevent the horrors of an infinite amount of energy spilling into a finite space), but chunks that fall into them knock parts of the mass back out into space, at a net gain to the total amount of mass that exists outside the scroll. There may also be unique forms of 6D lifeforms inside the scrolls.

Frankly, a lot of this thread has gone way, way beyond my understanding and I find it unfortunate that I do not know what questions to ask for elaboration.

Fair, we're talking about things whose Mundis analogue are almost incomprehensible to modern science. Let's go down to the planetary scale of how things work.
>Planetotrahesion holds the atmosphere of Lamdaar to the planet in place of gravity. What this means is that objects are forced "down" by pressure instead of fundamental forces. This only happens in open air, so buildings basically turn off gravitational force. Underground environments, however, have the centrifugal force of the checkerpiece, so a pressurized cave at the right location is an excellent habitation for humans. Many natural caves exist because of phrascic reactions.

>>71821064
Planetotrahesion is actually a misremembering of Cylindotrahesion. I guess it's basically the principle that sufficient mass coheres into a rounded flat shape along the 2d plane, except sufficient chunkiness makes it a cone or even tower shape.

When you think about it it makes some sense. Not the "he was right everyone its fucking happening" kind of sense but the "yeah, I can see why he would think that" kind of sense.
The sun is directly above at noon, this makes one point of the cube, from that geographical location exactly 1/4 of the earth to the east and to the west can see the sun before it hits the termination point and becomes night. Those termination points are where corners 2 and 4 start. If the sun is directly above in corner 1 then there must be a direct opposite on the night side making up corner 3. From corner 3's geographical center exactly 1/4 of the earth to the east and to the west will be shroud in night until you hit the termination point. These termination points meeting the sunward termination points complete corners 2 and 4 making a whole square. Why the fuck he calls it a cube I don't know, you can't even argue the north and south point addition makes it a cube because then it's just a fucking octahedron but whatever. The point where he went full retard was when he arbitrarily determined that these 4 points were both stationary points in time but also simultaneously hard anchored to earth with no defined point meaning each anchored point of the square passes through the 4 stationary points of the square in a day. That means you count each point as a when you consider days meaning each point must complete it's own 24 hours day. He then adds them up meaning it's really a 96 hour(totaled) day and a 16 pointed time star.
Tl;dr it would have made more sense if he sold us on a time ramiel because then it at least differentiates between northern and southern hemispheres allowing for explanations of axial tilt and its effects and he could have gone full crazy on the religious aspect. He could have even sold it as a time cross-polytope as that would still fall in line with his whole "all corners pass through all corners" rule and use time as the 4th dimensional axis.
