Planets

Summary:

• Temperate Tepui World

• Inhabitants: Talians

• Moons: Ithar, Selune

Tal was a temperate planet dominated by immense tepui formations—vast table-top highlands rising abruptly from lower plains. These structures created extreme geographic compartmentalisation, with each tepui supporting its own climate, hydrology, and endemic ecosystems. Waterfall systems cascading from plateau edges fed major river networks and fertile lowlands below.

The dual-moon system provided long-term climatic stability while introducing layered seasonal and tidal rhythms. The Talians developed as settled agrarian societies, often confined to individual tepui systems due to natural isolation. This resulted in parallel cultural development, strong regional identities, and limited planetary political cohesion.

Summary:

• Archipelago Ocean World

• Inhabitants: Morans (Aquatic and Amphibious subraces)

• Moons: Pelara, Neris, Oshuun

Mora was a fully archipelagic planet, lacking continuous continental landmasses. Thousands of island chains ranged from coral atolls to volcanic island arcs, each hosting dense and highly localised ecosystems. Biodiversity was exceptionally high, with rapid divergence between archipelagos.

The three-moon system generated complex and often extreme tidal interactions, enriching shallow seas and coastal zones. The Morans diverged into two primary subraces:

• Aquatic Morans, adapted to open water and reef environments

• Amphibious Morans, adapted to shorelines, mangroves, and intertidal regions

Moran societies were inherently maritime. Political and cultural organisation followed migration routes and island networks rather than fixed territory. Inter-archipelago contact was frequent, but planetary unification remained minimal.

Summary:

• Tundra and Boreal Snow World

• Inhabitants: Lethians

• Moon: Khal

Leth was a cold-dominated planet consisting almost entirely of tundra, boreal forest, and permanent snowfields. Ice sheets, permafrost, and long winters defined most of the surface, with short, limited thaw periods.

The single moon produced stable seasonal cycles but offered little thermal moderation. The Lethians evolved as a cold-adapted race, clustering settlements around geothermal pockets, subglacial rivers, and sheltered valleys.

Lethian societies were conservative, communal, and survival-focused. Population density was low by necessity, and cultural continuity was prioritised over expansion or technological experimentation.

Summary:

• Gaia-Class World

• Inhabitants: Three major Aseran races

• Moons: Kethra, Vaelor, Sythis, Ruun, Maelis, Torr, Ixa, Beloth, Naar, Calyx, Ureth, Zyra

Asera was a true Gaia planet, exhibiting long-term ecological equilibrium across its entire surface. Forests, plains, wetlands, deserts, oceans, and polar regions coexisted in sustained balance. Its position within the overlapping habitable influence of Ando and Var’s stars provided stable energy input and moderated climatic extremes.

Despite possessing twelve moons and elevated tectonic activity, Asera’s biosphere remained resilient. This allowed the emergence of three major sentient races, each adapted to different planetary zones yet capable of coexistence within an integrated planetary system.

Asera supported the highest population density and greatest societal complexity of all Pre-Erulian worlds, including urban centres, large-scale agriculture, and advanced non-magical engineering.

Summary:

• Highland Forest World

• Inhabitants: Kaelians

• Moon: Dravos

Kael was a highland-dominated forest planet, with dense forests covering most of its surface. Vast mountain systems formed the planetary backbone, giving rise to innumerable rivers that carved deep valleys and fed fertile lowland basins.

The Kaelians evolved as a highland-adapted race, constructing settlements along ridgelines, forested plateaus, and terraced slopes. Their societies were decentralised and regionally distinct, shaped by natural barriers and limited overland connectivity.

Engineering efforts focused on water management, slope stabilisation, and forest integration rather than monumental urban development.

Summary:

• Savannah Lake World

• Inhabitants: Threns

• Moon: Hesk

Thren was a savannah planet with no true oceans. Instead, it featured massive freshwater lakes distributed across broad continental interiors. Dominant vegetation consisted of thick, cactus-like megaflora capable of storing enormous quantities of water in underground reservoirs.

These natural water wells sustained life through prolonged dry seasons. The Threns evolved as mobile, savannah-adapted societies, migrating between lake systems and seasonal grazing zones.

Permanent settlements were rare and typically associated with stable lakes or major subterranean reservoirs. Thren culture prioritised mobility, water stewardship, and adaptive survival strategies.

Summary:

• Tropical–Desert Hybrid World

• Inhabitants: Virasians

• Moon: Loryn

Viras was a biome-diverse planet, characterised by alternating belts of tropical vegetation and arid desert regions. Rainfall patterns were sharply regional, with lush equatorial forests giving way to dry basins, dune seas, and scrublands.

Subsurface water flows connected many of these regions, enabling ecological interdependence across otherwise hostile terrain. The Virasians developed cultures capable of operating across starkly different environments, with trade and migration linking tropical and desert populations.

Virasian societies were flexible and resilient, but deeply dependent on stable climatic cycles, making planetary disruption particularly catastrophic following the Great Convergence.

• Subterranean Ice Moon

• Inhabitants: Kethrans

Kethra, Asera’s largest moon, had a barren and inhospitable surface. However, massive polar ice caps fed meltwater through fissures and faults into extensive subterranean cavern systems.

These underground environments were geothermally warmed and hydrologically stable. The Kethrans evolved entirely below the surface, adapting to low light and enclosed spaces. Their societies were structurally sophisticated, relying on precise water control, stone engineering, and closed-cycle resource management.

Surface habitation was neither viable nor culturally relevant to Kethran civilisation.
