The term „Caveworld“ is a little misleading. What a cave is, Wikipedia describes quite simply: A cave is a naturally formed underground cavity that is large enough to be entered by humans and is longer than five meters. This does not define how large a cave can become. Caves in the „Caveworld“ are larger than five meters, in fact, the rocky sky is at a height of more than ten thousand meters. Above the Akeanos, the ocean of this world, it stretches even to about 25 km!
In the rocky sky itself, there are gigantic crystalline transparent bubbles – called sun windows – at irregular intervals, with a thickness that can range from one meter to 20 meters and a radius of 15 to 500 meters. Light passing through this glassy substance is highly concentrated and is sufficient to adequately illuminate the entire vast cavity below. So with that, we should finally say goodbye to our common notion of a cave. There is also weather: sunshine, rain and snow, wind and storms. In summer, the sunny windows heat the world below up to 42° Celsius, and in winter, temperatures can drop to minus 10 degrees. Perhaps the term cave world should be replaced by „Orbis Subterra“, but then this saga would be called differently, and we don’t want that.
These huge rock domes are supported by pillars that strongly shape the impression a visitor has of this underground world. For these pillars are huge and cast enormous shadows. And, of course, there is also a daily cycle in the Cabeworld, and also seasons, because nothing has changed in the circulation of the planet. The total habitable area of the subterranean world is much smaller than on the surface. Large areas are made of solid rock, sometimes crisscrossed by a network of smaller cave systems into which no light falls. These areas are avoided and are mostly inhabited only by grotto-olms. Or even by ghastly monsters used to scare small children when they don’t want to finish their soup.
But since I already mentioned the ocean, there are of course continents. Akrania has approximately the size of Central Europe, the southern continent Veldoor the circumference of North Africa. In the west at the other end of the Akeanos extends Os, the largest continent, which is at the same time however completely uninhabited. And in the middle of the ocean between the continents there are the Cloud Islands. We will talk about them later.
Some may now object: Yes, if you don’t really realize that you are underground, why does it matter? Good objection. But it is important, because the fact that this world is under the earth brought to light properties that did not exist in prehistoric times. One in particular: magic.
