Agnis is the third of the three known, major moons of Chrysos.
North Polar Regions
The North Polar Regions of Agnis are dominated by an extensive polar ice cap broken by dark exposed terrain, fractured margins, and deeply incised troughs. The ice sheet covers the highest latitudes in a broad continuous mass, but its outer edge is uneven and heavily disrupted, with steep scarps, fissures, embayments, and isolated dark basins cutting into the frozen cover. In several sectors the polar terrain includes enclosed depressions and roughened uplands, giving the region a strongly broken and glaciated character.
Along the lower edge of the northern cap, the frozen surface gives way to darker volcanic and impact-marked ground. Craters, buried rims, and broad lowland plains remain visible beneath thin mantling and wind-spread surface deposits. One notable sector of the northern transition zone includes a concentrated field of sharp, bright ice pinnacles and fractured cold-trap terrain, standing out from the broader polar sheet as one of the most rugged icy landscapes on the moon.
The northern hemisphere is defined by the contrast between permanent polar ice and the darker underlying crust. Frozen deposits dominate the highest latitudes, while exposed rocky plains and cratered surfaces become increasingly common toward the equatorial belt.
Equatorial Regions
The Equatorial Regions of Agnis are dominated by dark plains, broad expanses of golden surface material, impact basins, and volcanic landforms. Much of the middle latitudes consist of low-reflectivity terrain interrupted by sweeping fields of pale yellow dust or frost-stained sediment spread across wide basins and plains. These lighter deposits form broad contiguous provinces, especially across the central and eastern equatorial belt, and sharply divide the darker exposed ground into irregular volcanic and impact-marked zones.
Several major craters and volcanic-looking depressions are visible across this region. Large circular basins with dark floors and raised rims occupy parts of the eastern equatorial zone, while smaller crater fields and degraded impact structures are scattered across the rest of the belt. Darker plains in the western and central low latitudes are crossed by long streaks and diffuse plumes of lighter material, suggesting sustained transport and redistribution of fine surface deposits.
The equatorial belt contains the broadest uninterrupted exposures of Agnis’s rocky surface. It is also the most varied region of the moon, combining cratered lowlands, dark volcanic plains, dust-covered basins, and localized areas of brighter material around impact and tectonic features.
Southern Polar Regions
The Southern Polar Regions of Agnis are covered by an extensive ice mass that is broader and more fragmented than the northern cap. Large sections of the south polar terrain consist of continuous frozen plains, broken shelves, enclosed icy basins, and fractured margins where the ice meets darker exposed ground. The southern polar zone also contains embedded rocky uplands, crater rims, and isolated darker masses rising through the frozen cover.
The transition between the southern ice and the lower latitudes is highly irregular. Ice fills depressions, spreads into channels and troughs, and gathers in broad apron-like deposits along the edges of rough terrain. In several areas, exposed rock and dark plains remain visible within the polar region itself, creating strong contrast between white frozen surfaces and the darker crust beneath.
The south has a more complex and broken glacial structure than the north, with broad lowland ice, exposed rocky interruptions, and several enclosed basins suggesting long-term accumulation across uneven terrain. Together, the southern high latitudes present Agnis as a moon of permanent ice, dark underlying plains, and heavily scarred polar margins.
