Composition and Structure of the World
Hyrkania is a terrestrial planet much like our planet Earth. This means that it is a rocky body, rather than a gas giant like Jupiter.
Hyrkania’s shape is very close to an oblate spheroid (a rounded shape with a bulge around the equator). Eons ago, Hyrkania’s interior structure, similar to other terrestrial planets, is layered. Hyrkania had an outer solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
However, through the ages, many catastrophic events (naturally occurring or induced by its vain inhabitants) occurred that ravaged and shattered Hyrkania beyond recognition.
The Hyrkania that stands today has many continental layers (often referred to as “World Shells” or “Shells“) which revolves around its core in separate directions and rotating speed. Each Shell are on average about 5,000 kilometers in radius and does not cover the entire ‘layer’ its sits on. Its common to have a few Shells revolving on the same layer.
The Shells revolves around the core in such complex and intricate pattern that almost every Shell seems to have its own day and night cycles (although their lengths will inevitably vary). There also exists shells that are either constantly in darkness or light.
No one knows exactly how many Shells exists on Hyrkania and ancient scholars often mused on the core of Hyrkania is like.*
