𖤓 Sier · SEAR

An exploratory world where desolate deserts, bizarre ecosystems, and the remnants of ancient civilizations coexist.
Under the scorching sun, water is the most precious resource, and across the deserts lie untouched ecosystems and ancient ruins sleeping in silence.

✦ World Characteristics

• Most of the land has undergone desertification due to long-term climate change.
• Thriving ecosystems have evolved not only aboveground, but beneath the sand, underground, and during the night.
• Fungi are used for far more than food—they are vital across all aspects of life, including textiles, dyes, medicine, and fuel.
• Ancient technologies coexist with low-tech civilizations, and instead of magic, the world relies on shamanism, rituals, and supernatural phenomena.
• The common currency is the Ser (S). Bartering is also widely practiced using water, rare fungi, livestock, and ancient relics.

◇ Geography

Red Desert The central desert where crimson sands stretch endlessly.
White Desert The northern region, rich in dazzling white sand, salts, and minerals.
Black Desert The western region, blanketed in black sand and jagged rock.
Glass Desert The southwestern region, covered in a ground surface melted and hardened like glass.
Mist Desert The eastern region, where dense fog rolls in during the night and dawn.
Canyonlands The northeastern region, home to colossal canyons and ancient ruins.
Green Oasis A precious southern-central green belt harboring wetlands and water sources.

⟡ Major Cities

Nakra · The Underground City

A subterranean city expanding in concentric circles around a massive underground cavern.
In the depths of its center sleep subterranean water sources, vast fungal colonies, and ancient facilities.

• Divided into specialized tiers: fungal farms, mines, workshops, markets, and storage facilities.
• Humans and subterranean races live side by side, their cultures naturally blending together.
• Subterranean Races: Unique races of various appearances residing within the underground city.

Talma · The Living Mobile City

A nomadic settlement built atop the carapace of a colossal land tortoise called an Orma.
Portions of the shell are repurposed into fungal farms, storage areas, and residential quarters.

• Daily life centers on fungal farming and caring for the Orma.
• When the Orma sleeps at night, the city settles down and rests with it.
• The Orma is regarded not merely as a mount or beast of burden, but as a cherished member of the community.
• Boarding and disembarking are managed via pulleys and rope ladders.

Korv · The Machine City

A colossal mechanical city built upon the mobile technology of an ancient civilization.
Contemporary engineers, unable to fully comprehend its ancient mechanisms, keep the city running through constant repairs and retrofits.

• Powered by a hybrid of steam, gears, pressure systems, solar power, geothermal energy, and fungal fuels.
• Inhabited by a high proportion of mechanics, engineers, and miners.
• Moves slowly on massive wheels, generating distinct vibrations and mechanical roars.
• When docked, it deploys elevator towers and folding footbridges to connect with the ground.
• Elevators handle passengers and small cargo, while freight lifts transport heavy supplies and livestock.

Nera · The Green Belt City

A stable settlement formed around rare wetlands and water sources nestled between the deserts.
Sustained by water and vegetation, the city has developed robust administration, trade, and food production, excelling particularly in textiles, dyeing, and craftwork.

• While agriculture and food production are viable, water resources remain strictly finite.
• Water rationing and management are directly tied to the city's politics and economy.

𖥧 Fungi

In Sier, fungi serve as food, essential resources, and the core biological cornerstone of the desert ecosystem.

◇ Livestock & Mounts

Numa · Livestock

Desert livestock characterized by long necks, thick coats of fur, small horns, and wide hooves.
Able to survive on minimal water and dry vegetation, they are a vital lifeline for nomads and mobile cities.
Transport · Milk · Meat · Wool · Leather

Sar · Mounts

Medium-to-large desert mounts reminiscent of a blend between an antelope, a camel, and a lizard.
With a low, broad build, wide footpads, and sturdy legs, they are exceptionally suited for long-distance travel across the sand.
