Biomes
Each realm and Mirae world consists of one or more biomes — large geographic areas shaped by environmental conditions such as temperature, rainfall, elevation, and magical potency.
Biome classification
All existing biomes can be quickly recognized and classified using 6

| 1 | Polar | Superhumid | Light | Lowland | Sparse | Whispering |
| 2 | Subpolar | Perhumid | Moderate | Low Elevation | Grassy | Glimmering |
| 3 | Boreal | Humid | Seasonal | Submontane | Wooded | Enchanted |
| 4 | Temperate | Subhumid | Frequent | Montane | Forested | Wyrd |
| 5 | Subtropical | Subarid | Heavy | Highland | Lush | Bewitched |
| 6 | Tropical | Arid | Intense | Subalpine | Diverse | Mystic |
| 7 | Supertropical | Perarid | Torrential | Alpine | Dense | Arcane |
| 8 | Subvolcanic | Superarid | Deluge | Subnival | Jungled | Eldritch |
| 10 | Volcanic | Dead | Monsoonal | Nival | Overgrown | Transcendent |
Temperature
Classification based on the annual average temperatures within the biome.

Polar — Very cold climates with an annual average of less than -15 °C.
Subpolar — Cold regions with an annual average of less than -5 °C.
Boreal — Cold temperate climates with significant seasonal variation and an annual average of less than 0 °C.
Temperate — Moderate climates with distinct seasons and an annual average of more than 0 °C.
Subtropical — Warm climates with an annual average of more than 15 °C.
Tropical — Hot climates with little temperature variation and an annual average of more than 25 °C.
Supertropical — Very hot regions with extreme temperatures and an annual average of more than 40 °C.
Subvolcanic — Extremely hot areas, with an annual average of more than 70 °C.
Volcanic — The hottest climates without any significant variation and with an annual average of more than 90 °C.
Evapotranspiration
Classification that reflects the rate at which water is lost from the biome.
Aquatic — Water environments; near 0% loss.
Superhumid — Extremely wet environments; up to 10% loss.
Perhumid — Very wet environments; up to 20% loss.
Humid — Areas with balanced moisture levels; up to 30% loss.

Subarid — Drier regions, where evapotranspiration exceeds rainfall; more than 50% loss.
Arid — Dry environments with high evapotranspiration rates; more than 60% loss.
Perarid — Extremely dry areas with minimal moisture; more than 80% loss.
Superarid — Ultra-dry regions, leading to harsh, desert-like conditions; more than 90% loss.
Dead — Environments with no available moisture and instant evapotranspiration; near 100% loss.
Precipitation
Classification based on the annual precipitation within the biome.
Scant — None or very rare, light showers; up to 100 mm annually.
Light — Occasional, gentle rains; 100-300 mm annually.
Moderate — Regular, moderate rains; 300-600 mm annually.
Seasonal — Distinct wet and dry seasons; 600-1000 mm annually.
Frequent — Frequent rainfall throughout the cycle; 1000-1500 mm annually.
Heavy — Consistent heavy rains; 1500-2000 mm annually.
Intense — Very heavy and often prolonged rains; 2000-3000 mm annually.
Torrential — Extremely heavy rainfall, typically in shorter periods; 3000-4000 mm annually.
Deluge — Near-constant, extremely heavy rains; 4000-5000 mm annually.
Monsoonal — Massive, overwhelming rainfall; exceeding 5000 mm annually.
Elevation
Classification based on the average elevation of the biome.
Belowland — Areas below sea level; bellow 0 m.
Lowland — Near sea level; 0-100 m.
Low Elevation — Slightly elevated areas; 100-300 m.
Submontane — Elevated terrain; 300-600 m.
Montane — Mid-elevation regions; 600-1000 m.
Highland — Elevated regions; 1000-2000 m.
Subalpine — High elevation; 2000-3500 m.
Alpine — High mountain zones; 3500-4500 m.
Subnival — Very high elevations; 4500-5500 m.
Nival — Extreme elevations; above 5500 m.
Biosphere
A classification that represents the percentage of the total land area in a biome, including vertical space (height), that is occupied by plant life and other forms of life.
Barren — No significant life forms, almost devoid of vegetation; up to 1% coverage.
Sparse — Minimal plant life, with isolated pockets of vegetation; up to 3% coverage.
Grassy — Dominated by grasses and small plants; up to 5% coverage.
Wooded — Scattered trees and shrubs, with some open areas; up to 15% coverage.
Forested — Dense tree coverage, with various plant species; up to 25% coverage.
Lush — Abundant and thriving vegetation; up to 35% coverage.
Diverse — High biodiversity, with a complex mix of plants and habitats; up to 45% coverage.
Dense — Very thick vegetation, with little light reaching the ground; up to 60% coverage.
Jungled — Extremely dense and complex vegetation; up to 80% coverage.
Overgrown — Vegetation dominates and overwhelms the landscape; more than 80% coverage.
Magic
Classification based on the magical potency inside the biome.
Null — A place entirely devoid of magic; exactly 0% potency.
Whispering — Magic exists in faint traces, like a soft whisper on the wind; up to 10% potency.
Glimmering — Magic is sporadic, appearing as brief flashes or glimmers that hint at hidden power; up to 20% potency.
Enchanted — The land is touched by magic, with areas and objects occasionally infused with arcane energy; up to 30% potency.
Wyrd — Magic is woven into the fabric of reality, with wondrous occurrences being a regular part of the biome; up to 40% potency.
