The Overflow

The Overflow is one of the many sub-realms of The Void. It might perhaps be thought of as a nursery of creation, a place where someone who knows what to look for, and can survive its extremely hostile environment, can access other realities besides the one from which they came. Like most of the Void, it seems to entirely defy the laws of physics, but it can perhaps be thought of as a place where the quantum state of matter and time is constantly in flux.

Why does Tempest call it the Overflow? I think because they think of it as the place where the "extra stuff" goes that didn't get incorporated into reality as we know it. Like a kind of "holding tank" for creation.

Tempest Kwake was connected to this realm of the Void in some integral way, like most of the other members of Voiders Anonymous are connected to specific Void regions, and many of their powers and abilities seemed to originate from that connection. They were immune to its incredibly destructive effects and could travel freely within it. They could even use their connection to the Overflow to create portals to and from other realities that, with help, could be accessed by other people. The only other person known to be able to travel with some of degree of safety in the Overflow is their sibling, Queen Sable Aradia. While she appears to be immune to its dangers, she does not have the same intimate understanding of the realm that her sibling did. She cannot navigate it nearly as proficiently, and cannot make use of its powers. Some speculate that Duke Uri Kwake, being the child of Prinx Tempest and displaying similar fiery powers, might be able to do so, but this is as yet unconfirmed. Whether or not any of the other Voiders can travel safely in the Overflow is unknown.

Geography

It's hard to describe the geography of this magical realm as geography unless you are extremely familiar with the Overflow. Fortunately for you, I am pretty familiar with it, since I have spent literally years wandering around through it. I know its ins and outs, I can read the signs it shows. I might not know the specifics of what each new reality holds, but I do know what to look for in each region. Most of the time.

The Overflow is a rough amalgamation of several types of realities, according to Tempest Kwake, the Voidtouched individual who was connected most strongly to the Overflow. Most of it appears as a realm of elemental fire unless you know exactly what you're looking for. The only one who knew what to look for was Tempest. There are the "real" realities, the ones that are very similar to each other with seemingly small changes. When arriving in these realities, you may not notice any particularly obvious differences. For example, the only obvious change between the 1337 Speak Reality and the reality Tempest spent the most time in, known as ""the Tomeverse" when differentiation has to be made, is that at some point, most modern writing systems were abandoned in favor of 1337 speak, a type of writing based off symbols, letters, and special characters. There are the "special" realities as well. These ones have something that makes them obviously very different from the "real" realities. One such is the "bubblegum reality," as Tempest called it. In this reality everything, up to and including the air, is made of bubblegum.

You can't really... move. I don't understand this reality or why it exists.
— Prinx Tempest Kwake, Voider

Some of these "special" realities are less concerning and have more obvious history behind them, including several ocean realities where the vast majority of Earth is water. Tempest preferred not to talk or think about these realities, knowing that something in the past went very wrong and that it's not outside the realm of possibility for any reality to have this happen. There are also "time dilated" realities where time runs counter-intuitively to most others. For example, there is a reality Tempest sometimes visited where there is a distant planet that was colonized and terraformed by House Sauropoda in the times of the ancient dinosaur civilization. The vast majority of the planet is sandy beaches with human shaped "AI" dressed in cabana chic. Time in this reality runs so slowly compared to other realities that several hours takes only a few minutes, and even two or three days will only take about twenty to thirty minutes. In the more dangerous parts of the Overflow, there are the "dying" realities. These realities are decaying in such a way that they are all ultimately consumed by the Overflow to keep them from infecting other realities. Tempest did not like to go into or talk about these realities, so very little is known about them. There are also several very small but important pockets of the Overflow that Tempest referred to as "nursery" realities, where new realities are born.

I don't really go into them very often. They don't need me mucking things up.
— Prinx Tempest Kwake, Voider

As such, not much is known about these realities. They could be the same as the "real" realities. They could be more like the "special" realities. Too much is unknown.

Ecosystem

I saw Overflow whales, which is... new?
— Prinx Tempest Kwake, Voider

Apparently the Overflow has whales. This was news to everyone, but especially Tempest.

Localized Phenomena

The vast majority of the Overflow is made of the very fires of creation. It is very hot, radioactive, and tends to literally burn anything in it (with exceptions for Voiders). There is also no gravity in the Overflow excepting in the various realities. Whether or not gravity works the same way in all of the realities or not is unknown.

Climate

Um... it's fire???
— Prinx Tempest Kwake, Voider

Fauna & Flora

Prinx Tempest has referred to Overflow whales before, but they haven't had the time recently to investigate further. Honestly, they were too startled by the appearance of the whales to do anything besides go to the nearest reality and hide in a corner for several minutes. Perhaps somewhat disturbingly, Prinx Tempest believed that the Overflow itself has consciousness, even self-awareness, and had extended conversations with this entity. No one else, not even the other Voiders, are entirely convinced this wasn't a persistent delusion, but all accept it might indeed be the case.

Natural Resources

Obviously there is fire in the Overflow, but there are also strange crystals floating in the plasma. What these crystals are, where they came from, and why they exist is entirely unknown.

The Company, in their highly illegal bioexperiments on literomancers and their kin, used something they called "Substance G". It is suspected that this is a Void tainted crystal, perhaps even one out of the Overflow. How they got such a thing, no one is certain at this time. Most of the people exposed to Substance G died.

Tourism

While tourism in the Overflow is not especially possible in the typical sense, with the aid of Queen Sable and her "force field" power, there has been some travel to and from other realities via Tang Portal. Most notably was The Great Migration, in which millions of people from the 1337 Speak Reality were evacuated to the Tomeverse before their reality was destroyed. The effort of this massive undertaking, however, cost Prinx Tempest their life. Prior to this, the Voiders and their friends would occasionally visit other realities on a lark. Tempest could sometimes be persuaded to bring people to the "beach" reality on vacation. Duke Uri and Princess Luna have spoken of a place called "The Cupcake Reality" that many people would really love to visit.
