Zilari, the Western Section of the Equator Sections East and West of the Habitual Belt on VOI 700 D, is a vast and largely unexplored region. Spanning approximately 370,000 square kilometers—comparable in size to Japan on Earth— Zilari shares identical climatic conditions with its twin region, Asari, due to the planet's tidal lock.

Unlike Asari, Zilari has never been a focal point of Exohuman settlement. However, it is the most explored section of the Western Habitual Belt, having been the destination of the Westward Passage Expedition (2626–2628), the only recorded Exohuman journey into the western half of the planet. The expedition was launched as part of an effort to traverse the Western Habitual Belt and confirm the Twin-Section Hypothesis—a theory that each region of the Habitual Belt has a climatic twin on the opposite side of the planet, resulting in similar environmental conditions, flora, and fauna.

The Twin-Section Hypothesis was successfully confirmed in Zilari, as its landscapes, ecosystems, and wildlife closely resembled those of Asari. However, the Westward Passage Expedition also uncovered an unexpected and unexplained mystery: the Native Tribes of Zilari spoke Shang Telu, the same language as tribes in the Eastern Habitual Belt, and followed identical creation myths and traditions. Yet, when questioned, these tribes had no knowledge of Asari, Nivari, or any distant Native groups beyond their own region. The Exohumans found no evidence of long-distance migration or historical contact, leaving the origin of this cultural connection entirely unexplained.

Despite these discoveries, Exohuman knowledge of Zilari remains limited. The Westward Passage Expedition was primarily a march-through journey, focusing on mapping and observational studies rather than in-depth research. No Exohuman settlements were ever established, and the Peace Treaty of the Gamma Age now prohibits further exploration.

As a result, Zilari remains an untouched frontier, its forests, rivers, and steppe regions home to civilizations and ecosystems that, despite their similarities to Asari, have developed in relative isolation.

Zilari's varied terrain offers a mix of plains, rivers, forests, and mountains, creating distinct ecosystems that sustain its Native Tribes.

• Lake Nirana – The largest freshwater body in Zilari, surrounded by lush rainforests. It serves as a critical resource for nearby Native communities.
• Lake Vemari – A high-altitude lake fed by glacial runoff from the Dabanga Mountain, known for its crystal-clear waters.

• Zilari River – The region’s primary river, stretching over 1,500 km from the Dabanga Mountains to Lake Nirana. It sustains agriculture and provides vital trade routes for Native settlements.
• Tovi River – A smaller but fast-flowing tributary of the Zilari River, passing through dense woodlands and supporting aquatic life.

• Nirani Rainforest – A dense jungle teeming with wildlife, spanning the southern half of the region.
• The Great Zilari Steppe – Open plains where nomadic tribes like the Votu follow seasonal migrations of large herd animals.
• Vemari Highlands – Fertile valleys in the northern regions, home to the Lavani and their advanced irrigation techniques.

• Dabanga Mountain – The tallest peak in the region, a sacred site for Native Tribes. Known for its extreme weather conditions and spiritual significance.
• Tavari Foothills – A range of rolling hills that transition into the steppes, offering natural protection against harsh weather.

The equatorial climate of Zilari supports diverse vegetation, with its ecosystems shaped by rainfall, altitude, and soil fertility.

• Rainforests – Thick jungle growth, including ancient trees, medicinal herbs, and parasitic vines.
• Wetland Vegetation – Aquatic plants thriving in the lakes and riverbanks, crucial for filtering water.
• Savanna Grasslands – Expanses of tall grasses, supporting migratory herbivores.
• Highland Flora – Hardy shrubs and mosses adapted to cooler mountain climates.

Zilari's wildlife is similar yet distinct from Asari, with species evolving to match the lesser Exohuman interference in the region.

• Grazing Mammals – Large, herd-based creatures roam the steppes and highlands, forming the foundation of native hunting and predator food chains.
• Aerial Predators – Raptors dominate the skies over the grasslands and forests, using heightened vision and agile flight patterns to track prey.
• Non-Predatory Birds – A wide variety of songbirds, migratory species, and waterfowl inhabit forests, wetlands, and grasslands. Some species exhibit highly specialized beak structures for feeding on particular plant species or insect populations.
• Stealthy Hunters – Feline-like predators lurk in the dense woodlands, relying on camouflage and ambush tactics to hunt small to mid-sized mammals and birds.
• Reptiles and Cold-Blooded Species – Various snake, lizard, and amphibian species inhabit the forests, wetlands, and rocky highlands. Some snakes are venomous ambush predators, while others are constrictors feeding on small mammals and birds.
• Aquatic Species – Rivers and lakes sustain a variety of fish, amphibians, and semi-aquatic predators adapted to cool, temperate waters. Some species are capable of brief land excursions, suggesting evolutionary adaptations for both aquatic and terrestrial survival.
• Insects and Invertebrates – Pollinators, burrowing species, and scavengers play a crucial role in forest and wetland ecosystems. Some possess reflective or light-diffusing carapaces, likely an adaptation to twilight conditions.

Zilari is home to an estimated 300,000 Natives, living in a variety of sedentary and nomadic communities. Unlike Asari, no permanent Exohuman settlements exist in this region.

Observations from the expedition in the Western Equator Section have revealed a recurring pattern among Native Tribes:

• The tribes of Zilari share the same creation stories and core beliefs as other documented Native societies across VOI 700 D.
• They speak Shang Telu, the common indigenous language, though with distinct regional dialects.
• Despite this linguistic and cultural connection, most tribes have no awareness of other tribes beyond their immediate surroundings.

• NANDA (Sedentary):
• Population: Approximately 70.000
