Zhenia is a nation located on the eastern coasts of the continent of Tarsis in Themys, primarily facing the Hanmaric Ocean. Zhenian geography shows great physical diversity, ranging from fertile lowlands and foothills found along most of the Golden Arc area, to the semi-arid basins and mountains to the west. Both due to terrain and climate, a vast majority of the nation's population and agricultural potential are focused in the east, particularly near the Gulf of Danguk.

While Zhenia's northern and southern borders are each defined by the Baekryong and Chang Rivers respectively, Zhenia's geography is primarily characterized by the existence of the Cheonsan and Mountains, which act as physical boundaries separating western and northern Zhenia from the remainder of the nation respectively. Arid plains, scrubland, plateaus and rocky deserts dominate the landscape west and north of such mountains, while the Taimir River Basin occupies much of what is central Zhenia. The Bukdu Mountains, with the Manho Heights at its northern end, runs through the length of the mostly mountainous Danguk Peninsula, accompanied by smaller, secondary mountain ranges.

Eastern Zhenia (Danguk Peninsula)

Main articles: Danguk Peninsula and Haedong Islands

Although its definition has expanded in recent years to include the Haedong Islands as well, Eastern Zhenia still often refers to the Danguk Peninsula and annexed islands, as clarified by the Constitution in 1979. Surrounded by the Gulf of Danguk, the Strait of Zhenia and the East Zhenian Sea, eastern Zhenia is home to a relatively high concentration of Zhenian inhabitants due to adequately temperate climate and flat terrain formed by alluvial plains, particularly in the coasts facing the Gulf of Danguk.

The Bukdu Mountains form the primary backbone of the peninsula, running from the Musudan Highlands to the southeastern edges of the peninsula. Due to the fact that the Bukdu Mountains are somewhat slanted to the east coasts rather than the west coasts of the peninsula, it is traditionally accepted that the eastern half of the Danguk Peninsula is on average higher in elevation than than the west, and that more rivers in the peninsula empty at the Gulf of Danguk rather than the East Zhenian Sea. Highlighting such fact, most of the region's major population centers are focused near the west coast than the east.

The Haedong Islands are a series of islands formed as a result of centuries volcanic activity at a tectonic hot spot around 2.4 million years ago, east of the Danguk Peninsula.

Northern Zhenia

Northern Zhenia stretches from the cold coasts of Bukhae Province to the northeastern branches of the Cheonsan Mountains and the Yangwei Mountains, and from Zhenia's northern borders to the Weisu River. A considerable part of northern Zhenia is mountainous and covered in forests, forming a natural border between central Zhenia and the cold, semi-arid plains extending to the north.

Central Zhenia

Central Zhenia comprises of the area between the Cheonsan Mountain region and the Gulf of Danguk, between the Taimir River and the Weisu River. With the exception of the Yangwei Mountains extending from the Cheonsan Mountains at its northwest and other smaller mountain ranges, most of central Zhenia is covered by the Central Zhenian Plains, a broad expanse of alluvial and flood plains that are primarily a part of the Taimir River Basin. Central Zhenia is therefore home to a majority of Zhenia's arable land. Few major mountains are observed in the region the most notable being Osong Mountain in the border between Imhae and Namhwa provinces.

With most of the macroregion being a part of the Taimir River basin and its tributaries, there are steep drops in elevation as the Cheonsan and Yangwei mountains give way to the Central Zhenian Plains, resulting in multiple alluvial fans near the edges of said mountain ranges.

Southern Zhenia

Southern Zhenia is a macroregion comprising of the area between the Taimir River and the Chang River, which in hand forms the nation's southern border with Yinguo. Mountains fan out from the southern branches of the Cheonsan Mountains, forming the southern end of the Taimir River watershed. The Taehwa Plateau, a densely cultivated region with an average height of around 900 meters (3,000 ft), marks the end of the extension of the Cheonsan Mountains. The plateau is famous for its limestone karst landscape.

The Balhae Peninsula extends to the east into the Gulf of Danguk after the Taehwa Plateau subsides. The Balhaeryeong Ranges form the backbone of the peninsula, somewhat mirroring that of the Danguk Peninsula. With alluvial plains stretching across the northern half of the peninsula and hills dotting its southern half, almost the entirety of the Balhae Peninsula is arable in nature, allowing it to be home to some of the most heavily populated regions in the nation.

The Chang River basin is primarily surrounded by mountains, with present-day Zhenian territory primarily spanning over the northern half of the basin and the remainder belonging to Yinguo today. The alluvial plains stretching from the midstream of the Chang River to its delta are primarily covered in forests.

Western Zhenia

Western Zhenia is a macroregion spanning all of what's west of the watershed created by the Cheonsan Mountains, which are home to the highest mountains in the nation. The western slope of the Cheonsan Mountains give way to the Sahaetan Basin, which contains the Haetan Desert, the largest desert in the nation. Lake Sagyeong located in Dragon Valley, the lowest point in Zhenia at -87 meters, is in the northern parts of Sahaetan Basin. Enclosed by the span of the Cheonsan Mountains running northeast to southeast and the Saghan Mountains to the west, arid regions of the Haetan Desert receive the smallest amounts of precipitation in the nation as a result of the rain shadow effect. Also being home to the highest recorded temperatures in Zhenian history at 48.9 C, the Haetan Desert is regarded both as one of the hottest and driest places in the nation.

Climate

Zhenia is home to a highly diverse climate, due to tremendous differences in latitude, longitude and altitude throughout its territory. Spanning between the latitude lines of 20.8° and 52.6° N, Zhenia's climate spectrum runs from hot in the south to cold in the northeast and humid in the east along the coastline to dry in the west, resulting in a climate that ranges from tropical in the south, subarctic in the northeast and desert in the west. Climate in much of Zhenia is influenced by seasonal winds and monsoons, bringing in a yearly oscillatory cycle of dry seasons and wet monsoons, in which a bulk of annual precipitation is highly concentrated in certain months of the year. Warm and moist air from the Hanmaric Ocean results in high precipitation and typhoons during the summer season, while the cold and dry continental air from the north dominates the winter season with cold weather and far less precipitation.

While absolute amounts of concentrations vary drastically from region to region, with arid regions such as the Haetan Desert receiving an average of 25 mm of precipitation each year while southern regions of the Balhae Province receive an average of 2,600 mm of precipitation of each year, precipitation is primarily focused in the summer seasons due to seasonal wind activity.

Natural disasters

Volcanic activity

Despite its location near active plate boundaries, Zhenia is home to only a handful of active volcanoes that have been active in the past 300 years, the most notable one being Mount Honghwa in the Haedong Islands. While there have been no life-threatening eruptions within the past 100 years due to the distance of active volcanoes from major populated areas, the most recent major eruption of an active volcano in Zhenia occurred in 1987, during the eruption of Mount Honghwa. The Ministry of the Interior, in tandem with the Ministry of the Environment, has been overseeing volcanic activities of both active and dormant volcanoes throughout the nation since 1974, while all signs of volcanic activity was formally included into the nation's emergency alert network since 1995.

Typhoons

In much of mainland Zhenia and the Danguk Peninsula, a bulk of the annual precipitation is focused in the summer seasons, a considerable portion of which often comes at the form of typhoons, which originate in the West Hanmaric Ocean and make their way westward before turning clockwise to the north to the East Zhenian Sea. While Central and Southern Zhenia tend to be more affected by typhoons in June and July, more typhoons tend to pass through the Danguk Peninsula and the Haedong Islands in August and September due to seasonal variations in wind speeds.

In theory, almost all of Zhenia's coastline can be at risk of typhoons; however, while most typhoons normally affected mainland Zhenia and the areas surrounding the Gulf of Danguk, recent trends since the late 2000s have seen increased frequency of typhoons making way further northeast, increasing the risks of flooding and significant property damage in the area. There have been increased concerns regarding the rise of surface temperature in the West Hanmaric Ocean, as well as varying patterns of temperature oscillation in the Hanmaric Ocean in general, in fear that such factors are contributing to stronger typhoons.

Human geography

Population distribution

The population distribution around Zhenia generally follows that of arable land distribution, with higher levels of population concentration observed in central, eastern and southern Zhenia than northern and western Zhenia.
