North Polar Regions
The North Polar Regions of Ivory are dark, cold, and heavily cratered. A thin cover of frost and ice lies across the highest latitudes, especially along the polar rim and within colder depressions, but most of the underlying terrain remains exposed. Large impact basins, crater chains, worn rims, and rough ejecta fields dominate the surface. The polar frost brightens the margins without concealing the moon’s battered topography.
The northern hemisphere preserves some of the oldest visible terrain on Ivory. Broad crater floors lie beside broken uplands and irregular scarps, while smaller impacts are scattered across nearly every exposed surface. The low albedo of the moon gives much of the north a muted charcoal and brown-grey tone, with the brighter polar deposits confined to limited zones of cold-trapped frost.
Equatorial Regions
The Equatorial Regions of Ivory are dominated by dark cratered plains, immense impact basins, and broad stretches of exposed rocky ground. Several very large circular basins define the equatorial belt, many with smoother, darker floors set inside sharply preserved rims. Between them lie dense fields of smaller craters, overlapping ejecta blankets, and rough highland belts broken by fractures and degraded escarpments.
This is the most varied part of the moon’s surface. Some sectors consist of relatively smooth plains marked by later impacts, while others are more broken and uneven, with clustered craters and irregular ridges cutting across older basin margins. The equatorial terrain is dry, airless, and geologically inert at the surface, with its present form set by repeated bombardment and long preservation under cold conditions. The low reflectivity of Ivory is especially evident here, where darker regolith and shadowed basin floors dominate much of the landscape.
Southern Polar Regions
The South Polar region of Ivory, while similar to the North Polar region in terms of cold temperatures and icy terrain, has distinct geological features. This area is slightly warmer, allowing for intermittent melting and refreezing of the ice. The terrain is a mix of smooth ice plains and rugged, rocky outcrops, creating a visually striking contrast. The South Pole is also home to several large subglacial lakes, which are kept liquid by geothermal heat from the moon's interior. These lakes are of particular interest to scientists studying the potential for microbial life. The dynamic interplay between ice and geothermal activity results in unique formations such as ice caves and meltwater channels.
The smallest of the moons, and indeed of all identified major bodies in the Atos System, Ivory enjoys a close orbit around the planet Momiji, which itself orbits Indigo.
