CONTINENS AUSTRALIS
The Southern Continent · What Is Known · What Is Not · The World Beyond the Crossing
"The southern continent is, in its majority, inhospitable. The desert that covers most of its northern interior is not a soft desert of sand dunes and occasional oases — it is a hard, rocky, sun-blasted landscape that offers nothing to those who venture into it and that the tabaxi have, sensibly, not attempted to inhabit or cross. What makes Solarhet viable is the coastal strip — a narrow band of habitable land along the northern coast where sea-moderated temperatures and coastal moisture make agriculture possible — and the two great rivers, which bring water from the invisible south and create fertile corridors that the tabaxi have developed into the most productive agricultural zones on the continent."
The southern continent is larger than the primary continent. Roman cartographers have established this much from the coastal surveys the Pilot's Guild has conducted across two centuries of the southern crossing. How much larger is less certain: the western coast has been followed south for approximately eight hundred kilometres from the northern landfall before conditions force every vessel back, and the eastern coast has not been followed east much further than the native jungle where Kha-Meru sits. The southern extent is a matter of ongoing scholarly debate between those who argue the available evidence suggests a continent of roughly one and a half times the primary continent's surface area and those who argue it could be considerably more.
What is known is the northern strip. The tabaxi civilisation of Solarhet occupies a habitable coastal band along the northern coast, fed by two great rivers descending from mountains whose sources have never been reached, bounded on the north by the Mare Profundum's southern shore and on the south by the desert interior that is the continent's dominant feature. Everything else — the desert's full extent, the mountain range that Varro's sources report as visible on clear days from the river cities, the western coast south of where the halfling pilots turn back, the eastern coast east of Kha-Meru, the continent's southern reaches — is, as of 1200 A.P., unknown.
I have been to Solarhet. I have not been to the continent's interior. No one I know has been to the continent's interior. The tabaxi, if they have explored it, have not chosen to say so. What the southern continent contains south of the desert and beyond its currently mapped edges is the largest single unknown in the geography of the known world.
Geography
The Northern Coastal Strip
The habitable band that Solarhet occupies runs along the northern coast's full documented extent, varying in width from a few kilometres where the desert presses hard against the shore to perhaps sixty kilometres at its widest, around the river delta where the Khet and Ura converge. The coastal strip is defined by two geographic facts: the northern sea's moderating influence, which keeps temperatures within the range that agriculture requires, and the river corridors, which bring water and silt from the interior and create fertility in an otherwise arid landscape.
The coast itself is generally accessible along the northern strip — natural harbours at Neb-Khet and the river delta approach, shallow-draft landings at the western fishing villages, and the wide harbour mouth at Khenet-Ura that the tabaxi call the yawning mouth and that ocean-going vessels can enter without significantly reducing sail. This is the part of the continent the world knows, and it is a narrow slice of what the continent contains.
The Interior Desert
Immediately behind the coastal strip — sometimes beginning within a kilometre of the shore, sometimes receding further where the river corridors push their influence inland — the desert begins. Varro describes it as hard: not the sand desert of romance, not dunes and oases and the possibility of travel with sufficient water, but a landscape of exposed rock, gravel plains, and sun-blasted terrain that radiates heat in ways that make the air above it visible. The tabaxi do not enter it. Not because they haven't tried, as far as Varro's sources can establish, but because the continent's interior desert is not the kind of landscape that admits repeated attempts. The expeditions that have approached the desert's edge and continued are the expeditions that have not returned with useful information, which the tabaxi regard as sufficient precedent.
How far the desert extends south is unknown. The two great rivers descend from somewhere, which means somewhere south of the desert there is an elevation and a climate that produces the water they carry. What lies between the desert and that southern highland — whether the desert is the entire interior or merely a northern band of it — is not known.
The Southern Mountains
On clear days, from the upriver settlements of Sek-Khet and Ura-Sek at the furthest navigated extent of the two great rivers, mountains are visible on the horizon. They have been described consistently enough across independent accounts that Varro treats them as established: a range, not a single peak, at a distance that the river currents' character suggests is several weeks' travel south of the furthest settled points. No expedition has reached them. The rivers continue south beyond Sek-Khet and Ura-Sek; they simply have not been followed. The priesthood has not prohibited southward river exploration. It has, consistently and with smoothness that Varro finds professionally significant, declined to organise it.
What the southern mountains are, where they run, whether they are analogous to the primary continent's Iron Spine or something different in character, and what lies on their far side: unknown.
The Western Coast
The western coast of the southern continent is the most comprehensively dangerous coastline documented by any pilot in the known world, and the Pilot's Guild's northern route documentation treats it with the unambiguous caution of people whose profession is managing risk and who have identified something that exceeds manageable proportions.
The prevailing conditions of the western ocean — swell patterns running consistently from the southwest, generated by the open ocean's full fetch over a distance that the Guild's most experienced weather-readers describe as longer than they can model with confidence — meet the western coast's rocky, cliff-faced character in a combination that produces surf conditions incompatible with any vessel currently operating on the known sea routes. The halfling pilots who have pressed south along the western coast, attempting to determine whether a circumnavigation route exists, have reached the furthest point any ship has reached and turned back on grounds that are documented in the Guild's archive with the characteristic specificity of people who are explaining a decision to their professional colleagues and want to be precise about what they saw. The furthest southern reach of the western coastal survey is approximately eight hundred kilometres south of the northern landfall. The coast continued south at that point. The pilots did not.
Whether a navigable passage exists south of the furthest surveyed point — a passage that would connect the southern ocean with whatever ocean lies east of the continent — is unknown. The theoretical importance of such a passage, if it exists, to the question of the eastern continent's accessibility from the south, is something the Merchant Council's navigational theorists have discussed and not shared publicly.
The Eastern Coast and the Native Jungle
The eastern extent of the northern coastal strip is defined by the native jungle — the vegetation that was here before the tabaxi arrived, the jungle that is not the rift-zone jungle of Khenet-Ura but something older and less understood. At Kha-Meru, three weeks east of Khenet-Ura along the coast, this jungle meets the sea, and beyond Kha-Meru the documented coast ends. A few halfling maritime surveys have pushed east of Kha-Meru by several days' sail, noting the jungle's character from the water without landing, and have turned back when the coast began trending southeast in ways that suggested a long journey to any eastward passage.
What lies east of Kha-Meru along the coast, how far the continent extends in that direction, and whether the eastern ocean is accessible from the southern continent's eastern shore: unknown.
Localized Phenomena
The Rift-Zone Jungle at Khenet-Ura
The transposition area of the Eleventh Permutatio — the zone the tabaxi came through in 600 A.P. — is visible as a circle of dense tropical jungle surrounding the sacred capital, bounded by a treeline as sharp as Sylvanmere's and as maintained. No tabaxi enters the rift-zone jungle to cut, clear, or cultivate. This is not a recent prohibition. It is a cultural absolute so ancient that the question of violating it does not arise. The jungle that came through the Rift is sacred. It has always been sacred.
Varro stood at the edge of this jungle and recognised something he had felt at the Sylvanmere treeline. His private notes record a hypothesis he has not published: that the rift-zone jungle and the elf forest are different expressions of the same category of thing, which he has been trying to name for thirty years. The tabaxi jungle came through the Rift six hundred years ago and shows no sign of decline. The elf forest is ancient and declining. They are not the same situation. But the quality Varro recognised — the sense of a boundary that is maintained rather than merely present — is the same quality in both.
The Two Rivers and Their Unknown Sources
The Khet and the Ura — Life and Light in the tabaxi naming — descend from sources that have never been located. The rivers have been navigated for six hundred years from their delta mouth to Sek-Khet and Ura-Sek. Beyond these cities, the rivers continue south. The silt they carry, the volume of water they maintain through the dry season, and the current character they present at the furthest navigated points all suggest source elevations and catchment areas substantially larger than the visible southern mountains alone could account for. Where the water comes from — what the continent's interior hydrology actually is — is one of several questions the tabaxi's subject-change reflex suggests they may have answers to that they have not shared.
What the Tabaxi May Know
The military assessment of Solarhet is that it has no external military capacity and relies on the continent's geography for natural isolation. This is accurate as far as it can be verified. What cannot be verified is whether the tabaxi have explored the interior and simply not reported their findings; whether the Living Goddess's six centuries of accumulated observation extends to knowledge of what the continent contains that is not available to anyone outside Khenet-Ura's temple; and whether the priesthood's consistent management of access to the interior — not prohibiting it, simply never organising it — reflects a decision about what the interior contains. Varro notes this without drawing conclusions he cannot support. The Living Goddess is waiting for something. Thirty years of reflection on the eleven minutes he spent with her have not established what.
Climate
The northern coastal strip: tropical on the coast, moderated by the sea into conditions that agriculture and dense human settlement can sustain. The rift-zone jungle around Khenet-Ura maintains its own internal climate, warmer and wetter than the surrounding coast, in ways that the jungle ecology supports and that the desert immediately to the south makes sharply anomalous. The river corridors are cooler and more humid than the desert through which they flow, creating the agricultural zones that Solarhet depends on. The coastal fishing villages experience the full range of the coastal tropical climate, including the storm seasons that the Pilot's Guild monitors carefully in scheduling the northern approach.
The desert: extreme. The temperature differential between day and night in the rocky desert terrain is large enough to fracture stone over centuries, which is what has produced the landscape's gravel-and-shattered-rock character. Water is absent in the functional sense — not completely absent, because the rivers prove that water exists somewhere to the south, but absent at the surface in the forms that make travel sustainable. The desert is not a place that humans, tabaxi, or any other known people cross. This may be because it cannot be crossed, or because what is on the other side has not yet been found sufficient reason to try.
The western coast's weather regime is driven by the southwestern ocean's swell patterns and the prevailing winds that the halfling pilots describe in their archive entries with the precision of people cataloguing something dangerous. Cold water upwellings from the deep ocean meet the cliff-faced western coast in conditions that produce spray, unpredictable currents, and the particular combination of wind and wave that makes the western coastal approach the most technically demanding navigation the Guild has formally assessed and then formally declined to certify.
History
The southern continent has a history before the tabaxi's arrival that is not known to primary continent scholarship and has not been offered by the tabaxi. Whether the continent was inhabited before the Eleventh Permutatio, by whom, and what became of them: unaddressed. The native jungle east of Kha-Meru is not the rift-zone jungle that arrived with the tabaxi, which means it was here before 600 A.P. What it was doing before the tabaxi arrived — who, if anyone, lived in its shade and what relationship they had with it — is not recorded.
The tabaxi's six hundred years on the continent constitute the entirety of the documented history of Continens Australis. It is an active, detailed history of a civilisation organised entirely around a continuously present divine being: the agricultural development of the river corridors, the construction of the sacred capital and the trade city, the establishment of the Kha-Meru community at the eastern jungle's edge, the opening of the northern trade route with the halfling crossing and its consequences for Solarhet's relationship with the primary continent. The detail of this history is recorded in the Solarhet articles and the Annales Mundi.
What the continent's history is before 600 A.P., and what the continent's geography contains south of what is currently known: the two questions that define what is not yet written.
