Cosmology

Many tales exist concerning what form the universe takes and so this was written to explain the form most true to reality.

Realms
pockets of reality "floating" for lack of a better word within the void, although many will either orbit another, usually larger realm, although most by shere number just fly through the void along ancient paths dating back to their creation.

As for their shape, realms can be of any size really, ranging from the size of a speck of dust on the tip of a flower (although this realm is only claimed to exist by a certain Loxodon scholar) to tens of thousands of miles across such as the various elemental realms however "most" are only three to a few miles across, but there are still hundreds of realms that are thousands of realms across its just the vast number of asteroids, as the smaller realms are known massively skews the average size. But for actual shape, most realms, or at least the energy barrier (sometimes called envelope) which contains whatever atmosphere a realm has is a perfect sphere with a point of gravity towards which all things in the envelope are drawn in the perfect middle of the envelope, however exceptions exist, for example the realm haven which is shaped like an egg and has its gravity point towards the rounded bottom of the realm,

As for how realms are created, there are two ways, the most common way a realm is created is when someone with strong creation magic abilities wills one into existence and they are able to shape the resulting realm as they so please. The other way a realm might be created is when just the right elements and mana collide into one another at just the right time to form an accidental realm, usually, resulting in a chunk of mithral being created which then floats around the cosmos until it collides with a realm and residents of that realm can mine the mithral and work it as they see fit. however chunks of other elements can form.

Axelo.
currently the most well known of the realms, axelo is a world half covered with islands whereas the other half is covered with water, originally a project made by all of the major god s and many of the minor gods, most of the major gods have since left to their own realms taking many of their children with them, but still many of both type of god still dwell on/in Axelo, besides the myraid of races and monsters they created who still dwell there.

Haven
Sometimes known as Heaven or Third moon, Haven is a realm in orbit of Axelo as well as the home of the Celestials. but perhaps its most unusual feature is its egg like shape and silverly, instead of the normal translucent envelope but inside are seven floating islands each with a different role.

The Elemental realms
Far from Axelo lies the Elemental Realms, a grouping of four realms in the form of a triangle, with the realms of Water, Air, and Earth representing the three points of the triangle while the realm of Fire is in the middle providing heat and light to the other realms, but each realm is a perfect sphere ninety thousand miles in radius, however in between the various major realms there is a number of smaller realms known as the "paraelements" where the main elements influences have melded together, these are things like steam, mud, magma, dust, etc etc, these are smaller realms ranging between a few thousand to thirty thousand miles in radius.

Realm of Fire.
the centerpiece of the system and the home of Infeva who has filled the realm with their favoured creations but the primary inhabitants of this ball of molten fire and burnt stone are the fire elementals.

Realm of Air.
the Home of tor-front the realm of Air is well, a tumoltous ball of air and other gases as the heat of the Fire realm causes collosual storms and winds to sweep across the entirety of the realm reaking havoc upon the inhabitants of this realm unless they live within one of the chunks of rock that were once asteroids before landing within the realm of air and now which are held aloft by the winds and can be turned into forestresses and cities by whomever finds them, usually air elementals but often times a dragon will claim one as a roost.

Realm of Water.
similarly to the realm of Air the realm of Water is a giant ball of water that serves as the homerealm of the Water elementals and officailly the brothers Bayo and Fjor but as those two spend most of their time pesting one another in Axelo, rule of the realm of water is a matter of debate between the different minor gods, powerful elementals, and true sea dragons who have claimed different parts of the realm with various degrees of legitmacy.

Realm of Earth
When it was first formed the realm of Earth was a solid ball of stone and ores and soil that its first inhabitants could "swim" through but over time as more creatures imigrated to the realm caverns and caves and tunnels have been created and filled back in by the building of cities and palaces and fortresses galore.

Uderon.
Uderon is a weird realm to describe as on one hand it is the second moon of Axelo, and on the other hand it could arguably be considered one of the elemental realms, or at least a para elemental realm but at the most basic Uderon can be consided the realm of Ice as it is the home of Lord Borealis after the transfer of power from Lord Borealis to the Judge, but within the realm perhaps the most obvious landmark on the entire realm is the collosual palace slash fortress of Borealis himself and occassionaly the members of the Unseelie court but most of them have their own palaces on uderon, axelo, or in small realms floating about. but besides the palaces across the realm there are amidst the frozen wastes and icey seas villages and a few cities for the mortal inhabitants of the realm, most polar elves, humani, and Goliaths but over time a few other races have made their way to this realm and made successful colonies.

the Twilight Forest
midway between Axelo and the elemental realms, causing the realm to be perpetually, albeit dimmly lit by the light radiating from both realm clusters is the realm of the Twilight forest, although it has many other names such as Lamannia or even the Feywild, the realm itself dispite what little life it recieves is full of life, with large swarthes of the realm being covered in trees hundreds of feet tall in forests only really broken by mountain ranges that erupt from the ground only to soar in the sky. but dispite the wealth of life in the realm, with most of the sentients being members of the various Fey species, there are also the palaces and fortresses of various members of the Seelie court and Arch-fey, but dispite that a few liches have come to the realm and built soaring towers so they might feast off the shear amount of life-force the realm generates around itself due to all of its inhabitants and the Horned god himself as this realm is one of his homes.

the Void
Before even the very first realm, before all things was the void, its unknown what created it, or if it just never really didn't exist, but no matter its origins the Void is the base layer of creation and is from what all things come from and what they will one day return to.

If some unfortunate soul were to find themselves within the void, they would see it as a blank, well void, devoid of such niceties as light, gravity, or even breathable air, however the void can be crossed by specialized "ships" although no one familar with ships would recognize them as such.

Leylines
Leylines are one of the most unknown things within the universe with only the learned mages and the gods even fully realizing that they exist so its hard to say with any certainty what leylines are,

The theory I myself find most likely to be true is that Leylines are "cracks" in reality to another plane of existence where magic is stronger if not all that there is within the realm. But no matter what they are, what is known for certain si what they do and a few properties of them, for example Leylines radiate out in all directions from a realm's gravity-point to a distance equal to the realm's radius squared but the farther away the leyline is the weaker it is, However if one knows the location of a leyline and is skilled in the arcane arts, they can siphon power from the leyline to fuel their spells.

But another, even rarer known ability of leylines is that with the right spells and Orchicalcum to channel the energy in the right way, someone with the right know how can "teleport" along a leyline until they reach a point unlong its length that they wish to exit at, when they reach they point they can activate what ever talisman they created to end the spell moving them along the leyline and they will immedieatly appear in "real space" wherever along the leyline they activated the talisman, but be careful as this is extremely dangerous and one can easily end up buried in a wall or miles high in the sky often with no way to get to safety.
