Core Class	Verdant Class M
Shorthand	VCM-O-T
Sub-classes	Verdant, Oceanic, Temperate
Atmosphere	78% nitrogen, 21–22% oxygen (elevated due to prolific photosynthesis), trace argon and carbon dioxide
Hydrosphere	78–82% (vast interconnected oceans, numerous mega-lakes, extensive river networks and wetlands)
Land Biomes	Expansive rolling grassy plains, dense temperate and subtropical forests, riparian zones around lakes and rivers, scattered highlands with coniferous stands

Gravity	0.98 g
Diameter	12,800 km
Age	4.8 billion years
Habitability	Superhabitable; exceptionally high biodiversity, fertile alluvial and volcanic soils, stable axial tilt and magnetic field
Life	Abundant multicellular carbon-based flora and fauna; complex ecosystems including large herbivores on the plains and arboreal species in the forests; potential for pre-sapient or sapient development
Orbital Period	372 Earth days
Moons	2 (one large major moon "Lunara", one small irregular moonlet)
Native Species	Verdantians (sentient humanoid species, early industrial stage); various non-sapient megafauna
Affiliation	Independent (pre-Federation contact); limited diplomatic ties with nearby systems
Notable Features	Bioluminescent fungal networks in deep forests at night, massive freshwater lake systems rivaling Earth's Great Lakes in scale, frequent but gentle auroras due to strong magnetic field interacting with solar wind

Verdantia is a Verdant Class M (Oceanic-Temperate sub-class) planet located in the Verdant Sector of the Alpha Quadrant. It is renowned for its lush, vegetation-dominated landmasses, extensive hydrosphere, and superhabitable conditions that support one of the richest known terrestrial biospheres outside of Class M garden worlds like Earth.

Physical characteristics

Verdantia orbits a stable G8V yellow dwarf star (Verdant Prime) at approximately 1.05 AU, placing it firmly within the habitable zone. The planet has a diameter of 12,800 km and a surface gravity of 0.98 g, making it slightly smaller and less massive than Earth but with comparable density due to a large iron-nickel core.

The hydrosphere covers approximately 78–82% of the surface, dominated by a single global ocean divided into several named seas by large continental landmasses and archipelagos. Freshwater mega-lakes and extensive river systems feed into these oceans, creating broad deltas and wetland transitions that blur the boundary between land and water.

Land coverage consists primarily of three large continents and thousands of islands. The continents feature vast interior grassy plains (often called the "Verdant Steppes"), bordered by dense temperate forests on windward slopes and highlands.

Climate and biosphere

Verdantia's climate is classified as warm-temperate with high overall precipitation driven by extensive evaporation from the oceans and orographic effects from mountain ranges. Average surface temperature ranges from 18–21°C, with minimal polar ice and no true deserts.

The biosphere is extraordinarily productive due to elevated atmospheric oxygen (21–22%), rich soils from ancient volcanic and alluvial deposits, and a long period of geological stability. Photosynthesis is highly efficient, resulting in planet-wide greenery visible from orbit as emerald continents veined with blue river networks and lakes.

Major biomes include:

• Grassy plains — vast savanna-like steppes supporting herds of large grazing megafauna
• Temperate forests — mixed deciduous and evergreen woodlands with multilayered canopies
• Riparian and lacustrine zones — wetlands, marshes, and lake shores rich in aquatic and semi-aquatic life
• Highland conifer stands — cooler, montane forests at higher elevations

Life and ecology

Verdantia's ecosystems support complex food webs with megafauna on the plains (including six-legged herbivores the size of Terran elephants) and arboreal predators in the forests. Bioluminescent fungi and symbiotic plant-animal relationships are common in the understory.

The native sentient species, the Verdantians, are humanoid with adaptations to high-oxygen environments (slightly larger lung capacity). They have reached an early industrial stage and live in dispersed city-states along major rivers and lake shores, relying heavily on sustainable forestry, aquaculture, and wind/solar power.

History

Verdantia formed approximately 4.8 billion years ago. Geological evidence suggests a relatively calm tectonic history with fewer mass extinctions than Earth, contributing to its superhabitable status.

First contact with off-world civilizations occurred in Stardate 58321.4 when a Federation survey vessel detected subspace communications from Verdantian city-states. The planet remains independent but has established limited trade and scientific exchange with the United Federation of Planets.

Inhabitants

• Verdantians — Primary sapient species; bipedal humanoids with green-tinged skin tones adapted to high UV filtering through dense atmosphere and canopy.
• Various non-sapient species — Including the Plains Thunderbeast (large herbivore), Forest Glidewings (arboreal predators), and Lake Crystal Jelly (bioluminescent aquatic organism).
