Yedal

Yedal (Cheonja: 霓達) is a cultural and geographical region which is located in northwest Sinju, between Nukigurun and Jeongmi. Yedal consists of three large islands: Yedal itself, Jeolbo, Seokdo and several smaller islands. The mainland of Yedal was formed approximately 11 million years ago at a complex convergent boundary between the Dangdo Sea Plate and the Sinjuan Plate.

Trade competition in Northern Yedal
Between the 15th and 18th centuries, fierce trade competition took place in northern Yedal. First, the country that achieved its heyday was Hwasan, which occupied most of northern Yedal between the 13th and 14th centuries and opened a golden age through various trade activities. However, when Jihwa was founded in the early 15th century, it began to compete with Hwasan by forming an independent trade route based on its abundant maritime capabilities. While Hwasan concentrated on trade to the south and had an edge in spices, etc., Jihwa had an advantage in resources by focusing on trade between Nuki and Jeongmi and northward using the Northern Ocean.

In the late 17th century, political instability in northern Sinju caused pirates to appear, and as Nuki began to expand westward, Jihwa suffered a major economic blow. As a result, Hwasan once again took the lead in the trade competition and exerted great influence in the Yedal region. However, the Jihwa-Nuki War finally ends with Jihwa's victory, and as piracy calms down, Jihwa begins to advance south, as far as Namju, and gradually expands the scope of its trade.

Eulhae War

 * 1935 2.24 Nukigurun presentes an ultimatum to Nabei claiming that the events happened in Nabei were not a revolution, but a rebellion, and that if the troops were not disbanded by Samwol fifth, Nuki would accept Nabei royal family’s request for assistance and deploy troops In Nabei. After the ultimatum to Nabei, Nukigurun concentrates it’s forces on port X in the east and prepares for landing operation. The Yedal strongly condemn Nuki's ultimatum, while rushing troops toward Nabei. However, they did not actually expect the war to break out, and they were not fully prepared for the war. As a result, only 7 Division reinforcements gathered in Nabei.


 * The 1935 3.5 Nuki declared war on Nabei and Yedal in the name of suppression of insurgents and launched a massive landing operation. Unprepared, Yedal failed to deal effectively with simultaneous landings, and within a week six major ports in Nabei were occupied. Subsequent small-scale battles have left the Allies losing one after another to Nuki's overwhelming firepower, and even lost the control of the sea in A strait, making it is difficult to defend the coastline. So the army retreated inland to prepare for a defensive battle in the Jangbaek Mountains.


 * 1935 3.28 Nuki, who was advancing rapidly, encounters Allied forces at Y, and the first major battle occurs. Despite being outnumbered, the Yedal forces fought against Nuki, fiercely resisting using the geographical advantages of mountain ranges and weapons supported by Jeongmi. The battle ended with Nuki's victory, but the severely damaged Nuki stopped advancing. Allied forces build pillboxes across the mountain range to counter Nuki.


 * Owol forth, After completing preparations for the War, Jeongmi and Meisaan declared war on Nuki, forming the Allied forces. However, this was a great mistake, which Nuki claimed they intended only to help the Nabei royal family's formal request for support, but Yedal sent troops to his own interests, and that Jeongmi and Meisaan's declaration of war was imperialistic ambition. Mincang, Gaoxiong, Fusen, and Hachuabsh, who were dissatisfied with the two countries' global hegemony, signed the Chukyo pact in support of Nuki and formed the Contingent Power.


 * 1935 7.2 Meanwhile, Nuki's advance to the defensive line formed by the Allies in the Jangbaek Mountains was blocked, and a new landing operation was set up to land in northern Yedal. The Allies also knew that Nuki was trying to mount a massive landing operation, but did not know where they would land. They expected Nuki will land in O because the port was developed, making it easier to supply and the surrounding flat area makes easier for the Nuki armoured division to advance, and they can halve Yedal with only advancing 500 kilometers. In addition, there was a fierce air battle over Hwasan, and Nuki mobilized a battleship to bombard O, so the allied forces gathered troops on O. But this was a trap, and Nuki's real goal was somewhere else.


 * 1935 7.8 Nuki made a surprise landing of 18,000 troops on Gwangpyeong. Allied forces, especially Jihwa, were embarrassed by the unexpected landing and rushed troops to Gwangpyeong. However, due to reforms centered on the Navy and Air Force, Jihwa's army was weak, with only 16 Division, of which only 4 Division was well trained. Nuki's advance with armour division gave the Allies a big push, and they were broke through without time to prepare for a defensive battle through the mountains.


 * Jijung, the capital of Jihwa, fell in 7. 24 and the royal family and leaders fled to Jeongmi. Northern Yedal's supplies were transported via Jihwa's railway system, but as Jihwa fell into Nuki's hands, Hwasan became unable to be supplied and was besieged by Nuki.


 * 1935 7.31 Allied forces engaged in a fierce naval battle with Nuki to retreat troops from Hwasan. But jeongmi and Meisaan’s naval forces were concentrated in East sea, and the Western fleet wasn’t enough to fight with Nukigurun’s navy. Crucially, Allied powers lost the battle in T sea, which became a disaster to the forces remained in Hwasan waiting to retreat. Nuki launched an all-out offensive against Hwasan, and within two weeks, Hwasan also collapsed and 170,000 Allied troops were captured.


 * Nuki, who conquered northern Yedal in 1935 8.2, planned two operations to take control sea around Yedal before a full-scale invasion to Xencovia. The first was the occupation of Seokdo. Although Jihwa surrendered, an exile government led by the king was still in existence, deploying submarines to the North Sea using Seokdo's ports, and hunted Nuki’s transport fleets. In addition, Johyeon airfield, located in Seokdo, was also a threat, so Nuki tried to consolidate it’s influence on Yedal by occupying Seokdo. After the defeat in the T battle, the Jeongmi Navy did not pose much of a threat because it was focused on defending the coast, avoiding all-out fighting. However, the Jihwa Navy was small in number, but was equipped with battleships and heavy capital ships, and was conducting fleet raids in conjunction with submarines, so Nuki first targeted the annihilation of the Jihwa fleet. The second was to gain control in the West Sea. At that time, the Allies received a lot of supplies from Namju, so they tried to prevent supplies by blocking West Sea. This also allowed us to expect a sea route connection with Mincang.

Geography
Yedal is an area located between Jeongmi and Nukigurun, and consists of the main island and an annexed island. It's total area is 707,262km², and consisted of 8 countries. A spine of east–west mountains, the Jang-baek mountains, dominates the geography of Yedal, stretching over 1,600 km (1,000 mi) across the island, with many mountains over 4,000 m (13,100 ft).In the southern region, the mountains are generally gentle and there are many flat lands. Overall, it is very suitable for farming because it has temperate weather, and through this, Xencovia, which occupies most of the southern region, has historically been able to maintain strong national power without being occupied by neighboring countries.The northern region is generally very mountainous. Since the temperature is low and was inappropriate for rice farming, barley and wheat were mainly grown, and trade, fishing, and mining were used as the driving forces of the economy rather than agriculture.

The highest peak of Yedal is 00san Mountain located in Areum, and its height is 5682m.

Climate
The climate of Yedal changes significantly based on the Jangbaek Mountains.The weather in the southern region is generally mild, and the four seasons are clear. In summer, it is hot and humid due to the influence of the NamXencovian Sea Low, which pours Xencovia lot of rain. In winter, the North Sea air mass is blocked by the Jangbaek Mountains, causing low-temperature and dry winds.

The weather in the northern region is generally cold. Since it is located on high altitude, it is generally cool and dry in summer. On the contrary, in winter, it is very cold due to the influence of the Great North sea high. In particular, Jihwa and Noknukbeol, which have many mountains, are famous for their very heavy snowfall.

Fauna
Yedal region is home to a diverse fauna, because of its different habitats, like steppes, northern taigas, and temperate broadleaf forest. Deer inhabit mainly in the northern regions, and reindeer are often found. They are also be found at the southern area, but they are smaller than deers living north. Tigers live throughout the mountain range, frequently appearing in the center of the mountain range, which made one of the reasons for the poor transaction through land routes between the northern and southern regions. Currently, tigers are almost gone, and countries have designated and managed tiger protection zones in remote areas to protect tigers.

Culture
Due to geographic factors and climate influences, the cultures of the northern and southern regions are very different. However, it can be said that the essence of both regions is the same because they were greatly influenced by Jeongmian culture. Meanwhile, the cultures of the northern region are divided into Hwasanese and Jihwan regions, because the two countries have maintained their independence for a long time and created their own culture.

In terms of architecture, Xencovia in the south had many magnificent and colorful buildings by using its huge and wealthy national power, and has an open structure to make it sunny and airy. The architectural style of the Hwasan is also splendid, and it is beautiful, especially because the cultures of various countries are harmonized thanks to the country’s active trading policy. In addition, the landscape culture was very developed. Jihwa's architectural style is a little different from that of the two countries. With low temperatures, frequent snow, and, above all, lack of wood, so the architectural style of mixing stone and wood was developed and the house looks simple. In addition, the walls are thick to prevent the wind, and there is a passage inside the house to move. Meanwhile, in order to soothe the cold, Jihwa's heating technology was greatly developed, and they used to heat or bathe using hot springs rising from the ground.

Administration
Yedal is divided geographically by three regions and administratively by eight countries.
