Agelcer Crag Gardens

History

Geography

Agelcer Crag Gardens is an immense, mountainous expanse of floating canyon plateaus, broken cliff face structures, and immense stone ledges of the higher regions. Located within a highland temperate transition zone of the Twilight Age world Agelcer is in stark contrast to the abyssal, lightless depths of Aer or the glacial frozen wastes of Agaro. Agelcer is unique in its paradoxical coexistence of an incredibly savage, geologically violent environment holding dense, localized pockets of immense fertility that exist as the Agelcer Gardens.

Topography and Geology

The crags are a product of both tectonic uplift from geological antiquity, the glacial carving of thousands of years of ice and groundwater erosions. As soft rock eroded more readily and densely composed mineral stratum stayed firmly intact it left behind a vertical and broken landscape, massive monolithic crags that shoot from the land floor, natural stair like terrace systems leading down impossibly sheer cliff faces, and hidden between these are hanging valleys, secluded basins, and natural amphitheaters filled with thousands of years of trapped sedimentary deposits.

These locations are what make the crags 'gardens.' The cliff face itself is a fractured wall of sandstone, extremely porous limestone, and rugged, crystalline intruded metamorphic strata, rich in banded mineral deposits of iron-rust red, stark pale ivory, grey-blue shale, and granite colored dark by moss growth.

Climate and Hydrography

The climate of the fractures of Agelcer varies from region to region as determined entirely by the elevation and wind-resistance factors of a given crag face, the higher crags are immensely exposed to wind, high solar radiation, and drastic changes in temperature throughout a given day, but in the sheltered terrace gardens below conditions are remarkably stable and hyper humid and can remain this way through the thermal resistance they achieve from being located in depressions that are surrounded by sheer rock walls.

Morning fog is endemic to Agelcer and forms thick layers in the lower canyons that embrace the stone monoliths. The primary source of water for the Agelcer Crag Gardens is not a surface-dwelling river, but rather massive subcutaneous aquifers bleeding from the porous rock faces in the form of countless crystal clear springs which form delicate, small streams and waterfalls throughout the Garden areas, the constant mineral seepage has over thousands of years deposited vast amounts of Travertine and calcified rimstone.

That combine with the moderate seasonal rains to form a massive (albeit transient) runoff stream that rushes throughout the Garden region.

Traversability

Movement is exceedingly difficult through the Agelcer Crag Gardens, due to the extreme verticality and fragmentation of the landforms there is no ground level passage of any length. Travelers will be forced to either navigate crumbling limestone ledges or to use the only means of safe traversal, the erosion corridors that wind through the impossibly stacked rock.

Plants

Terrace Flora (Garden Basin Vegetation)

The flora of the Agelcer Crag Gardens is exceptionally niche and relies on a fine balance between barren rock and constant seepage from groundwater. The vegetation of Agelcer appears as isolated, hanging pockets of abundance, unlike the continuous and open tundra of Agaro, or the dry wastelands of Adisay. The so called "Gardens" sprout on elevated terraces wherever the elements (wind, debris, and bedrock) are in close enough proximity for small micro-ecosystems to exist for long enough to establish themselves.The genetically rich pockets on the higher terraces provide the most diversity of plants on this highland.

Moisture-absorbing mosses, thick shrubs, and vibrant flowering perennials, are the most dominant species due to their continuous nutrient supply from the trickling groundwater. Plants must have strong lateral root systems because there is very little soil, thus binding and stabilizing the soil and cliff with roots. Because each terrace is separated by an insurmountable drop-off, the rock crags are like an archipelago; neighbor terrace gardens often share only completely unique (endemic) species that are dependent on their position, and mineral content.

Because all of the plants are sustained by dissolved rock, the flora is highly saturated, with emerald moss, silver shrubs, red flowers, and golden lichen growing in abundance.

Cliffside Flora (Lithophytes and Hanging Gardens)

The immense vertical cliffs of Agelcer support gravity-defying, lithophytic flora. These plants do not grow in soil at all, and inhabit the mineral ledges, fissures, and weeping rocks that have seeps in them. To survive in the harsh, windswept climate of the highlands, these plants have abandoned tap roots for holdfasts, aerial roots that dig into the rock and bind the plants to the stone. If the relative humidity is always high enough in hidden chasms or near waterfalls, enormous root mats and trailing vines are hung on the cliffs.

Many of the plants of this high terrain have a unique evolutionary feature called biomineralization. Since the springs are saturated with heavy minerals and dissolved calcium, the plants of these areas have highly calcicole external tissues. The water continually flows over the plants, leaving a casing of travertine and crystalline minerals, essentially building the plant as part of the rock over centuries of growth.

Spring and Wetland Flora (Seep Basin Ecosystems)

The weeping seep pools andhanging wetlands are the most stable of Agelcer's various micro-ecosystems. Because they are continuously sustained by deep, inexhaustible groundwater aquifers, these isolated hydrophytic communities are always healthy and thriving, even when the highlands outside of the crags become severely drought-stricken. These wetlands and seep pools are dense with reed beds, and white blooms, and tall sedges. In the still portions of the pools, wide, buoyant vegetation floats on top of the water, sending dangling roots down to absorb minerals.

Nearly every seep pool on the Agelcer crags is its own unique, localized ecosystem; due to isolation, the same plant community would never be found anywhere else in the known Twilight Age world.

Adaptations (Endemism and Biomineralization)

It is not large environmental changes, but radical geological fragmentation, instable terrain, and high mineral content that drives the evolution of Agelcer Crag Gardens. Instead of spreading outward quickly through geographic expansion, plant life thrives by rooting itself deeply and differentiating rapidly at a local level. Nearly every species is also a metallophyte or a hyperaccumulator, tolerant of the dissolved stones and heavy minerals present that would kill most vegetation.

The ever present threat of rockfalls dominate the ecosystem. These inevitable slides occur constantly; an entire garden might crash down into the valley without notice, leaving bare rock that will eventually be repopulated by trickling highland water.

Animals

Terrace Fauna (Garden Basin Species)

The fauna of the Agelcer Crag Gardens represent the epitome of biological isolation and hyper-specialization. Functionally analogous to a terrestrial archipelago, Agelcer's sheer stone crags have supported innumerable, suspended micro-ecosystems isolated by sheer, unfathomable drops. The biological hubs of the region reside in the relatively sheltered terrace gardens. Adapted for their perilous existence across sheer, crumbling ledges and sediment drifts, these herbivores, pollinators, and predators boast incredible agility, hyper-developed stereoscopic vision and incredibly low centers of gravity.

Because it is near-suicidal for any number of terrace species to traverse the bare vertical rock between gardens, the geographically isolated nature of these populations allows a mind-boggling number of geographically endemic (unique to the locality) species to arise. Each is fiercely territorial, adapted to precisely the flora of its specific home terrace. The only means of predation possible are criesis (camoflage) and ambush; the dense moss and hanging vines simply preclude any sort of prolonged pursuit, leaving hunters to strike only with swift, lethal precision.

Cliff-Wall Fauna (Saxicolous and Vertical Species)

The sheer, exposed faces of limestone and precipitous chasms are home to an entirely separate collection of gravity-defying saxicolous (rock-dwelling) fauna. Within this deadly, vertical space between gardens, these creatures carve out an existence on mineral shelves, weeping crevices, and the thick root-curtains of hanging flora. Their morphology is strictly dictated by their verticle niche. Lightweight, highly articulated skeletons combine with strong gripping appendages and climbing claws, as well as an assortment of specialized adhesive pads that allow them to creep across wet rock, even in highlands gales.

Their only defense is crypsis. Through layered, muted pigmentation they blend into the granite cliffs and reddish iron strata, or seem to melt into hanging lichen-strands. Their migration does not follow the continents in sweeping, annual migrations, but rather, slow vertical, seasonal treks following shifting humidity levels along weeping walls.

Wetland and Spring Fauna (Seep Basin Ecosystems)

The permanent, isolated spring-fed rimstone pools and hanging wetlands represent the single most stable biological niches on the crags. Due to their origin in deep, underground aquifers, the seep basins are capable of supporting permanent populations of amphibious grazers, aquatic predators, and humidity-dependent scavengers. These wetland creatures are adapted for steady, shallow mineral flow by means of highly specialized, hydrophobic outer membranes, webbed appendages, and floatation-adapted bodies.

These elevated wetlands have remained separate for many millennia, resulting in a massive micro-endemism. Each distinct spring ecosystem may house entirely unique species of amphibians, aquatic invertebrate, and detritivores adapted with exquisite precision to the specific chemical and mineral contents of that spring.

Behavioral Cycles (Isolation, Ephemeral Corridors, and Collapse)

Fauna behavior on the crags is driven by water permanence, rather than a broad-scale continental migration. The baseline is an intense biological isolation. Yet during seasonal torrents, the crags become momentarily frantic, as overflow of the springs and runoff cascades forge ephemeral (temporary) water bridges between terraces. During these few weeks, geographically separated populations have brief opportunities to migrate, breed, and hunt across the crag system before water levels drop, severing the temporary corridors.

The overwhelming apex force that shapes life on Agelcer, however, remains gravity. Gravity, in the form of spontaneous rockfalls, collapses of terrace edges, and shifting mineral strata, serves as the brutal, localized ecological resets. The complete destruction of a thriving terrace ecosystem, the vaporized thousands of tons of rock, forces its few survivors to desperately disperse and seek new, vertically displaced refuge.
