On Kepler, seasons are locations.

Because of the Static-Cell Model, Kepler is divided into four permanent seasonal zones. Unlike some other planets, these seasons do not move across the planet as the year progresses.

Instead, specific regions remain locked into their respective climates throughout the year.

Zero Axial Tilt

Kepler possesses an obliquity, or axial tilt, of nearly 0°.

Because the planet does not tilt toward or away from its sun during its orbit, solar radiation strikes the same latitudes with nearly identical intensity year-round.

This eliminates traditional time-based seasons and helps lock regions into permanent climate states.

Retrograde Rotation

Unlike standard planetary bodies, Kepler rotates from East to West.

This retrograde rotation reverses the Coriolis effect. Major wind currents, atmospheric pressure systems, and ocean currents curve to the left in the northern hemisphere.

This fundamentally alters global moisture and heat distribution and drives the atmospheric “conveyor belt” from the North toward the East.

Orbital Eccentricity

While Kepler’s axial tilt remains static, its orbit around its star is highly elliptical.

The planet’s physical distance from the sun therefore fluctuates throughout its revolutionary cycle, triggering global temperature spikes and drops.

This orbital eccentricity is responsible for the extreme global weather events known as the Raging Seasons.

The northernmost region of Kepler is locked in perpetual summer.

This extreme heat is driven by a massive geothermal “super-plume” beneath a thin planetary crust, combined with localized greenhouse atmospheric variance.

The North effectively acts as the planet’s radiator, generating constant heat independent of solar radiation.

Holy Metzia is the only sovereign nation located entirely within the Alsummer Zone.

Other Sovereigns Partly Located in Alsummer

• Eiria
• Uttaria
• Teranua

The southern pole consists of a massive, high-altitude ice continent.

Characterized by its extremely high albedo, the continent reflects much of the solar radiation it receives back into space.

This keeps the region perpetually frozen and generates massive reserves of sinking, cold air.

Salvation Island, the base of the World Council, is located within this zone.

Sovereigns Partly Located in Alwinter

• Atteria
• Jureslavia
• Delsur

The Alspring Zone occupies the eastern corner of the world and experiences perpetual growth and bloom.

The reversed Coriolis effect pushes rising warm air from the Alsummer Zone eastward.

As this air travels east, it collects enormous amounts of moisture and deposits it over the region.

The result is a constant cycle of warmth, rainfall, and biological growth.

Sovereigns Partly Located in Alspring

• Uttaria
• Eiria
• Atteria
• Delsur

The Everfall Zone is defined by constant coolness and aridity.

By the time atmospheric currents cross the planet from the east, they have been almost entirely depleted of moisture.

These winds descend over the west as dry, cool air, creating an environment of perpetual autumn, crisp air, and natural preservation.

Sovereigns Located in Everfall

On the Western Continent, the following sovereign nations are almost entirely located within the Everfall Zone:

• Teranua
• Hordad
• Sang
• Jureslavia

Located at the center of Kepler, the All-Season Zone acts as the planet’s meteorological “drain.”

It is the convergence point where the warm, wet winds of Alspring collide with the dry, cold winds of Everfall.

At the same time, the heat of Alsummer battles the frost of Alwinter.

As a result, this is the only region on Kepler that experiences dynamic, shifting weather throughout the year.

Sovereigns and Recognized states Within the All-Season Zone

• Evelyn — Entirely within the zone
• Kanata — Entirely within the zone
• Eiria — Partially within the zone
• Atteria — Partially within the zone

Although Kepler’s geographic climate zones remain permanently fixed, the planet still experiences global intensifications caused by its highly elliptical orbit.

When these weather patterns reach their absolute peak, they are classified as the Raging Seasons.

☀️ Raging Summer

June–August — Perihelion

During this period, Kepler reaches its closest approach to the sun.

The resulting influx of solar radiation triggers Raging Summer in the North.

The global heat spike also pushes the Alwinter Zone to its warmest temperatures while amplifying the warmth of Alspring.

🍂 Raging Fall

September–November

Raging Fall is characterized by violent, drying winds across the western regions.

These conditions create an optimal mixed-crop season for agricultural regions such as Sang.

❄️ Raging Winter

December–February — Aphelion

Kepler reaches its furthest point from the sun.

The resulting reduction in global solar radiation triggers Raging Winter in the South, pulling temperatures downward across the planet.

🌸 Raging Spring

March–May

Raging Spring occurs during the transitional period of planetary temperatures.

The season brings extreme precipitation, flooding, and hyper-growth to the eastern regions of Kepler.
