Agrovionimb Island
Type
Island
Agrovionimb is the final surviving city of civilization. For more than 1,137 years, it has endured after demons overran the mainland and destroyed nearly every known nation.
Long before the Fall, the island of Agrovionimb was part of the Kingdom of Druvavarbia, a maritime nation consisting of four great islands: Agrovionimb, Andavum, Marate, and Porduroria. These islands formed a prosperous trade network linking the sea peoples and coastal civilizations of the world.
Today, Agrovionimb stands alone. The other islands fell silent after the demon invasion. The city that once served as a minor trading port is now the last refuge of civilization, its harbor filled with the descendants of refugees from every surviving culture.
The sea protects them. Demons cannot create—and therefore cannot build ships.
Across a thousand years of survival, the people of Agrovionimb have preserved knowledge, rebuilt society, and continued a singular act of defiance: they build ships and send them back into the demon-ruled world in the hope that something, somewhere, might still survive.
Geography¶
The island of Agrovionimb covers approximately 2,500 square miles and lies near the southern edge of the Dragon’s Maw, a turbulent region of ocean currents and shifting sea lanes.
The island’s geography is divided into three distinct regions:
Northern Forests
Dense temperate forests covering rolling highlands. These provide most of the island’s timber.
Central Swamp
A vast wetland occupying the center of the island. Its existence defies normal climate and hydrological expectations, making it one of the greatest unsolved mysteries of the old kingdom.
Southern and Western Coasts
Rocky coastal cliffs broken by natural coves and one major harbor.
The city of Agrovionimb itself sits along the western coast, where a deep natural harbor allows safe anchorage for large vessels.
Ecosystem¶
The island hosts a surprisingly diverse ecosystem shaped by both ocean influence and the presence of the central swamp.
The northern forests support typical temperate woodland ecosystems, while the coasts host seabird colonies and marine life supported by strong ocean currents.
The swamp ecosystem is far more unusual. It contains:
- dense reeds and mangrove-like trees
- massive insect populations
- amphibious predators
- strange bioluminescent fungi
The swamp’s biodiversity appears far richer than the island’s climate should support, which was the primary reason the old kingdom established a research outpost here.
Ecosystem Cycles¶
The island’s ecosystems operate on several interlocking natural cycles.
Ocean Migration Cycles
Large fish migrations pass near the island each year, providing the primary food supply for the city.
Storm Renewal Cycles
Seasonal storms replenish freshwater reservoirs and maintain the island’s wetlands.
Swamp Water Cycle
Unlike natural wetlands, the swamp appears to maintain a stable water level independent of rainfall or tide, suggesting unknown underground water sources.
This anomalous hydrology remains unexplained.
Localized Phenomena¶
The central swamp is one of the greatest natural mysteries in the known world.
Based on the island’s elevation, rainfall, and drainage patterns, the swamp should not exist. The terrain should drain naturally into surrounding coastal waters.
Yet the swamp persists.
Strange observations recorded by earlier Druvavarbian researchers include:
- water levels that remain stable regardless of rainfall
- deep sinkholes leading into submerged caverns
- rare gases bubbling from the mud
- unusual magical readings detected by arcane instruments
Before the Fall, the island hosted a royal research station dedicated to studying the phenomenon. The wars preceding the demon invasion prevented any final conclusions from being reached.
The mystery remains unsolved.
Climate¶
Agrovionimb experiences a maritime temperate climate influenced heavily by surrounding ocean currents.
Typical conditions include:
- mild summers with steady sea winds
- cool, wet winters
- frequent coastal fog
- powerful seasonal storms
The surrounding ocean prevents extreme temperatures but creates unpredictable weather patterns.
The swamp region tends to be significantly warmer and more humid than the rest of the island.
Fauna & Flora¶
Flora¶
- coastal hardwood forests
- salt-tolerant grasses
- mangrove-like swamp trees
- medicinal herbs cultivated in terrace gardens
- vast kelp forests offshore
Fauna¶
- seabirds and cliff-nesting gulls
- amphibious swamp reptiles
- migratory ocean fish
- swamp insects and amphibians
- small woodland mammals
The swamp ecosystem contains the most unusual wildlife, including species not found anywhere else in the former kingdom.
Natural Resources¶
Agrovionimb’s resources are limited but carefully managed.
Primary resources include:
Timber
Harvested from northern forests for construction and shipbuilding.
Fish and Marine Life
The city’s main food supply.
Kelp and Seaweed
Used for food, rope fiber, fertilizer, and alchemical ingredients.
Stone
Quarried from coastal cliffs.
Freshwater Springs
Provide drinking water for the city.
The swamp itself is rarely harvested due to its unpredictable terrain.
