Rasatal (rah-sah-tahl)

Geography

Rasatal is a disk-shaped realm, 3600km wide, where one face is habitable while an 'underside' is unenterable. Though it is flat, the edges of the habitable face experiences a shift in gravity's pull that feels like climbing up and down increasingly steep slopes. This makes it more difficult to leave Rasatal at the edges.
The very center of this disk is a 40km hole. It is a perpetual cyclonic system that experiences unique weather conditions that differs significantly from the surrounding regions. It is calm and tranquil but forces that typify a storm whip around Rasatal's inner rim like a semi-permeable wall; that also acts as its ground.

Ecosystem

The Twelve Slices

12 Zones

	11. Vicia A murky, damp marshland where the very ground beneath shifts and sinks, making it difficult to maintain footing.	12. Jura A high, flat expanse of land that sometimes shifts and tilts, creating sudden drops or steep inclines.	1. Perm A massive glacier that creeps and crawls across the landscape, carving out deep valleys and towering ridges underneath.
10. Decon A vast expanse of grasslands that shift and twist, forming hills and valleys, sometimes even creating sudden gullies or canyons.				2. Creta A deep, winding gorge with walls that shift and move, sometimes creating new paths or even closing off old ones.
9. Teria A coral reef that constantly shifts and grows, creating new underwater landscapes and sometimes even forming islands.		d12		3. Ordo A range of mountains with peaks that rise and fall unpredictably, and valleys that twist and turn in impossible ways.
8. Silvur A dense forest of tall trees that constantly rearrange themselves, creating new paths and opening up clearings that weren't there before.				4. Quater A barren wasteland where sand dunes shift and reshape themselves, sometimes revealing hidden oases or swallowing up entire parties.
	7. Missi A massive impact crater with constantly shifting walls and floors, creating new obstacles and hazards for those who dare to explore it.	6. Slvia A serene lake that periodically transforms into a turbulent, churning whirlpool, complete with dangerous underwater currents and vortexes.	5. Tert Massive peaks that can suddenly erupt, spewing ash and lava across the surrounding terrain.

Clock-wise Calamities

The 12 sections of Rasatal are a series of dynamic and unpredictable landscapes, oriented like a giant clock face, that defies conventional understanding. Each environment is unique, and its boundaries are in a constant state of flux, with a wide range of natural disasters that can occur at any time.

— GMs can alter the difficulty in traveling to the center by including needing to cross sections of the neighbouring slices for encounters in 2 normal and 1 extreme condition or vis versa

Localized Phenomena

Otherside

Some undefined, gravitational strangeness is usually blamed for the 'underside' which also partly curves over the rim towards the habitable side; effectively creating a 100km high wall. Attempts to enter into this region, leads to the trajectory gently curving away from the Otherside until they miss entirely. It is impossible for anything, intelligent or otherwise, to enter.

Climate

Unconventional Ground Energy

Liquids and a pseudo-atmosphere tend to want to bubble closer to the center. However, this movement is countered by an influx of energy coming from the other direction via the strange energy emanating from the rim of Terakon. These ionized particles move like a tide through the earth; feeding energy into the many disaster level storms throughout.
The pattern and strength of the convection currents makes it such that it is easier enter through the very edge of Rasatal and leave near the center than vis versa.
