The City Inevitable
A world is the term applied to any type of reality growth that occurs at a simultaneous point on both the Grim and Gossamer Webs. Fields of reality within Gateheart are not worlds (they are classified as “pockets”). Fields of reality that attach to either the Gossamer Web or the Grim Web, but not to both, are known as “demesnes”. A field of reality that attaches to both webs but in non-simultaneous places is called a “tunnel”.
A world can be any size or shape, contain any number of indigenous lifeforms (including no life forms at all), have any type of environment. All that a world must have to be classified as a world is a Feyside and a Shadow to attach it to the Webs, and the potential to generate at least a single world seed.
There are different categories of worlds that exist, some naturally occurring, and some artificial. They are as follows:
Cluster world: A naturally occurring type of world, although they can be engineered. A cluster world is a world that develops as a bundle of smaller worlds and world seeds develop in close conjuncture, until they eventually merge. Cluster worlds tend to have their own planar structures and may require special means to travel from area to area, but once harvested they still yield a single bundle of seeds. The Great Wheel is an example of a cluster world.
Drupe World: A singular world that only contains a single planar structure. It may produce any number of seeds, however. Most worlds are drupe worlds.
Bud worlds: A bud world is a tiny world that may yield a single seed. It is very small, and typically grows off of another world. Some bud worlds are grown intentionally for specific purposes, using specially created seeds.
Slave worlds: A slave world is a type of world that is created specifically through seed engineering. It has a short life expectancy, but typically develops a single type of culture in rapid succession. These are typically created by individuals with intentions of harvesting slaves or resources rather than pets. The Thesid Overmind originally pioneered slave world technology roughly an aeon ago.
Clone worlds: Clone worlds are bud worlds that retain the distinct growth patterns and characteristics of a larger world. Clone worlds very rarely occur, typically when timespace activity within a world causes it to create a parallel world to address a temporal paradox. However, around the time slave world technology became viable, the House of Forgotten Names developed a means of creating intentional clone worlds, which are commonly used for resource purposes.
Hell worlds: Hell worlds are worlds created from red world seeds. A hell world doesn’t grow for the purpose of prosperity, nor does it grow based on a pattern provided by a Feyside. A hell world grows rapidly and chaotically, like a cancerous growth. As such, they tend to be violent, dangerous, and unpleasant for anyone unfortunate enough to inhabit them. Hell worlds are very rarely cultivated, and most are naturally occurring. When a hell world is formed, it is typically isolated to control its growth. It has some uses, however- it produces additional red seeds, which are a vital part of seed weaponry technology. Additionally, hell are the only worlds that can regenerate themselves. If a connection point where a hell world died is exposed to red seed energy in large doses, it will eventually regrow itself, not only retaining its exact parameters but also emulating its timespace progression to the letter, picking up exactly where it left off when it died.
