Faun
Faun is the second of the major moons of the planet Thalassa.
North Polar Regions


The North Polar Regions of Faun are dominated by an extensive frozen cap broken by deep fractures, broad scarps, and heavily reworked icy terrain. The highest latitudes are covered in thick bright ice, but that cover is not uniform. Large cracks, broken shelves, enclosed dark basins, and zones of roughened surface texture interrupt the cap across much of the polar belt. In the northwestern transition zone, the rough uplands known as the Verdis Marches define one of the clearest thresholds between permanent frost and darker exposed ground, while farther east the jagged icebound heights of the Stonecord Highlands rise sharply from the surrounding cap as clustered blade-like formations and uplifted frozen ridges. These northern names fit naturally with the cultic landscape associated with Faun, whose worship around Sylvapolis centers on wooded uplands, carved standing stones, and hidden passages rather than monumental urban sanctuaries.
Along the lower edge of the northern cap, the frozen surface gives way to darker exposed ground, impact-marked plains, and broad transition zones stained by wind-transported material. Craters remain visible both within and beneath the polar deposits, and several dark lowland patches cut into the ice margin. The most prominent of these is the Sylvaron Basin, a broad enclosed depression whose darker interior stands out strongly against the brighter frozen north. East of the basin, the volcanic-looking rise called the Dilëtaz Crown emerges as one of the most visually dominant northern features, while the broken boundary zone of the Therizis Verge marks the transition into more disrupted eastern terrain. The north therefore combines thick permanent ice with an older underlying crust, giving the region a fractured and deeply layered character.
Equatorial Regions
The Equatorial Regions of Faun are dominated by dark plains, broad belts of wind-spread surface material, and large deposits of bright frozen or salt-rich ground. Much of the equatorial zone consists of low-reflectivity terrain broken by craters, shallow basins, and long streaks of lighter material extending across the middle latitudes. These pale expanses form some of the most visually distinctive features on the moon, especially where they spread across smooth plains and basin floors. The broad central low-reflectivity province is commonly designated the Faunion Expanse, a name derived from Faun’s zodiacal identity and used for the moon’s largest uninterrupted central belt. Around it, the broad lighter zone of the Grovefall Plain and the transitional corridor called Hollowgate Reach distinguish some of the moon’s most recognizable middle-latitude surfaces, their names echoing the hidden caverns and descending ritual routes of Faun’s cult without reducing the landscape to overt liturgical description.
Large dark provinces occupy much of the central belt, with scattered impact craters and degraded rims preserved across the surrounding terrain. In several regions, bright deposits gather in broad irregular patches rather than in narrow isolated fields, giving the equator a mottled pattern of dark exposed ground and pale reflective surfaces. This is especially visible in the western trenchlike sector of Sylven Chasma, the enclosed depression known as Kavron Hollow, and the lower basin system called Garland Basin. Farther east, the volcanic-looking depression of Panagion Patera and the broken eastern threshold known as Leafmother Threshold mark a region where bright deposits and dark uplands intermix more abruptly, while the fracture field of Rootsong Fossae further breaks up the eastern equatorial terrain into ridged and segmented blocks. The middle latitudes also preserve evidence of surface transport, with diffuse plumes and streaked mantling extending across wide areas of the landscape. In mapped usage, the Faunion Expanse, Grovefall Plain, Hollowgate Reach, Sylven Chasma, Kavron Hollow, Garland Basin, Panagion Patera, Leafmother Threshold, and Rootsong Fossae together define the most important equatorial regions of Faun.
Southern Polar Regions
The Southern Polar Regions of Faun are brighter, rougher, and more topographically varied than much of the equatorial surface. A broad southern ice mass extends across the highest latitudes, but its margins are highly irregular and broken by exposed rocky uplands, crater clusters, and dark protruding ridges. Much of the south polar terrain is arranged in bands of frozen ground, fractured ice, and rugged mountainous relief. The broad glacial margin known as the Oakwreath Shelf forms one of the clearest southern shelf-like features, while farther west the pale drift zone called the Morrowine Drift marks a more diffuse field of redistributed frost and fine material across the lower polar transition.
One of the most striking southern features is the large concentration of steep, dark mountainous terrain rising along the lower polar belt. These ridges and massifs project through surrounding frost and ice deposits, creating a strong contrast between bright frozen plains and darker exposed rock. Nearby lowlands contain many small bright-rimmed pits and clustered depressions, while the polar margin itself shows signs of repeated fracturing, collapse, and uneven accumulation. This southern ruggedness is further distinguished by the vent-marked zone of the Satyric Fumaroles and the steep boundary of the Petroglyph Scarp, both of which add localized structure to the broad polar landscape. The southern hemisphere is therefore defined by the meeting of permanent ice, cratered plains, and rugged uplifted terrain. In mapped form, the Oakwreath Shelf, Morrowine Drift, Satyric Fumaroles, and Petroglyph Scarp give the southern polar region a more localized vocabulary while preserving the page’s broader description of a broken, bright, and topographically varied south.
