Primespace is the most recent world to have breached their crystal sphere. Unlike most worlds, they seem extremely unified and in constant contact with each other. They seem very open to trade and commerce, and welcome merchant vessels with open arms. Some have reported trying to learn how their economy works, but money moves in this world faster than can be tracked by anything short of an ancient dragon sage.
Technologically speaking, the people of this world have harnessed metal and lightning to create wonders and weapons that even archmagi struggle to replicate. This can apparently be traced back to an event in their past called the War of Divinity, a conflict in which the weave was broken in their world for a time, and technology stepped up to take magic's place. When magic was restored, technology and magic merged into a new form the likes of which have not been seen anywhere besides within the Illithid Union.
However, traders beware: testing has shown that their devices are so reliant on small quirks of their laws of physics, that they often break in horrible and disastrous ways when brought outside their crystal sphere.
As far as we can tell, "Primespace" owes its name to the fact that Prima was been much closer to its planescape than most wildspace systems, and also was the only populated planet in their system. As a result, for most of their history their world was known primarily as "The Prime Material," as the people felt a greater need to differentiate their world from the other planes than the other planets in the sky.
Close study is still required, but this seems to be a fairly standard sun: a yellow class-H spherical Fire Body.
A silver class-D spherical Earth Body, with no atmosphere. A common pattern in this setting is that, unlike most spheres, apparently only Prima has any native life at all. Another pattern is that they have seemingly named most planets after a member of their Dawn War pantheon. It is yet unknown if these planets have any magical connections to their namesakes.
A yellow class-E spherical Earth Body, with a thick inhospitable atmosphere. A warning to travelers: The atmosphere is apparently so dense that from the outside, it can easily be mistaken for an Air Body.
A green-and-blue class-D spherical Earth Body. This is seemingly the only planet in this system that can support humanoid life natively. However, the inhabitants of this planet have developed spells and devices to temporarily survive the inhospitable environments of their neighbor planets.
Oddly, the people of this world seemingly did not name their continents at any point, neither before nor after their world was restructured by a spellplague. Our current theory is that this world has been so interconnected for the majority of its history, that regions were known purely for their political borders.
Spelljamming ports can be found in almost every major city, having been adapted from ports for their own advanced air vessels or built from the ground-up in mere months. Recurring trade vessels can request electronic devices to identify themselves and request landing, while unidentified vessels tend to be greeted by heavily armored military ships before even reaching Prima's atmosphere, and escorted to the surface.
A red class-D spherical Earth Body. It has a thin atmosphere, but the air is only breathable in small settlements and laboratories, with large ongoing projects to terraform this planet into a copy of Prima.
A collection of thousands of Class-A to class-C Earth bodies, of various shapes. According to Priman mythology, these are all that remains of the Abyss after Primespace's Asmodeus won their equivalent of the Blood War.
A pale orange class-G Air Body. Has over 80 moons, none of which seemingly are able to support life.
A pale yellowish-green class-G Air Body. This planet is seemingly known primarily for having a very intricate ring system. Notably, after being introduced to Spelljamming technology, they have started planning to bring ships of people here from Prima. As such, infrastructure is currently being built near the planet to allow resupply before returning. They have also apparently allowed extraplanar travelers to restock here, assuming you put on a good face and have enough money to pay for it.
A grey class-F Air Body. Interestingly, the storms on the surface act more like plate tectonics than weather patterns. According to Priman scholars, this planet was named as such because they initially believed it was made of solid stone.
A blue class-F Water Body. While it does have oxygen-rich water and can easily support aquatic life and exploration, the atmosphere surrounding the planet is extremely poisonous.
A light gray class-C elliptical Earth body. This is the odd one out, as the only non-life-supporting planet in their system not named after a Dawn War deity. According to Priman scholars, this planet was a recent discovery just before the War of Divinity, and was kept as part of the pact between gods that ended that war, as the last vestige of the old wildspace system.
Unlike most worlds, Primespace has had a large number of deities rise and fall. However, due to the spread of power, their deities apparently are quite a bit less powerful than gods in most other worlds. Tracking what gods exist here would be a monumental task due to the overwhelming quantity of them, so instead, we list here the most notable events in determining the Priman pantheons.
Like most worlds, Prima had a Dawn War. However, unlike most Dawn Wars, only a few gods formed: Ao, Erathis, and Pelor - representing Justice, Law, and Light, respectively. These gods created mortal beings, then chose who they thought were worthy from among them to become new gods when the Primordials rose up.
The strangest part of their Dawn War, however, is the story of this universe's version of Tharizdun. He was the leader of the Primordials, and was far more powerful than most of them. So powerful, in fact, that he managed to defeat Ao, splitting them into the gods Bahamut and Tiamat. From here, he should have won - but miraculously, the gods managed to pull ahead and imprison Tharizdun instead, winning the Dawn War. This is consistent with the thematic pattern of Tharizdun being imprisoned, which is an event that occurs in most universes with a Dawn War. However, it is concerning in this case: apparently, this universe's Tharizdun was not a god to start with, and instead ascended when he absorbed most of the raw power of an Overgod.
Interestingly, this world had an event very similar to Nerathspace's War of Winter, which saw the not-to-uncommon ascension of the Raven Queen to godhood. The biggest difference was the effect it had on the cosmology of Primespace. In this world, the War of Winter was the origin of Prima's seasonal cycle, as the continuation of a pact between Corellon, Pelor, Sehanine, and the Raven Queen.
In our research, this is the single largest-scale ascension event in any known universe, with hundreds of new gods and demigods ascending and dying extremely rapidly. Prima's entire wildspace system was destroyed in a spellplague, and this sparked a war between the heavens and hells of Primespace. Supposedly, their Asmodeus eventually capitulated, and he gave his stolen power to the other gods for them to rebuild their material world, in exchange for being allowed to use that power first to finish the Blood War once and for all. Now Primespace is effectively entirely devoid of demons, and is seeing levels of prosperity almost unheard of on other worlds.
