Yamamura
Yamamura was a catastrophic world-ending event that began in a Surochi village that worshiped the southern deity Suzaku where the former emperor Malong battled the giant yaoguai Rou Shan which ended in both their deaths and a crack that led in all the demons of Kindao into the mortal realm. This war forced all dominating factions of the planet to form a brief union and was widely considered one of the most devastating events. It led to other world-affecting occurrences, such as the end of the Ren dynasty, the birth of Shadow Rot and the Itami cult, and the dismantling of the Seigun Shogunate.

History
During the reign of Dragon Emperor Ren of the Shilon kingdoms they thrived. The nomadic hordes were silenced, old enemies were subdued, and the kingdoms outside the walls were safe. For a time, the kingdoms of Shilon felt at peace, yet Emperor Ren yearned for more.
The solidated nomadic tribes of Surochi proved themselves peaceful, but their loyalty and faith in the heavens remained unclear. Their land was barren and of no use, but Ren's pride and thirst for achievement were unsavory. Wanting to annex Surochi into the Shilon law, but even Ren knew any means of force or violence would leave his reputation a tyranny, and will only create feared enemies instead of trusted allies. So, in 3100 RH, Emperor Ren sent a pilgrimage group led by Malong to the south to persuade them peacefully. Malong's charm was able to stir the Patriarch of Surochi, Elder Tsering to his favor but wasn't enough to gain his approval. Frustrated by his refusal, they remained loyal to Ren's plan of peaceful negotiation. But instead of journeying back, Malong decided to stay behind, for he was captured by Surochi's hospitality and culture.
In the middle of the night, a vicious evil turned the sands black and a colossal earth yaoguai named Rou Shan tore up from the ground in a village named Yamamura and attacked the temple where the Surochi Patriarch resided, but was thwarted by Malong and his men. Mighty, the former emperor stood true, their battle laying waste to the temple and the monks within. Finally, after five days, Malong subdued the yaoguai king, chopping him into seven pieces. One of them being a tooth that pierced Malong's skin with a fatal poison. After Malongs death, the severed remains of Rou Shan picked themselves up and hammered a lavish hole into a revered temple of the Vermilion bird of the South; Suzaku. Causing a great eruption that quickly turned all standbys into dust.
For an hour the desert plain and the excavation remained quiet but were soon interrupted by the sounds of a screeching militia of yaoguais. They climbed on top of each other like a colony of ants and began scattering across the globe. The first wave began finishing their conquest of Surochi. Due to the low presence of a military system within Surochi, the people in the steppes of Rusuke and the dunes of Kalbaar stood no chance. They then came for the Hanggai steppes of southern Monkhu and narrowly slaughtered all of the nomadic tribes there when a battalion of Monkhu troops intervened. They then swam the ocean and headed for the islands of Tekkan and engaged in deep combat with the Seigun, but were utterly defeated by the samurai of clan Tatsu who rained steel upon the yokai with their firearms.
Withdrawn from the islands, the swarm of beasts set their eyes on the rest of the southern Monkhu and Midora Provinces. But after the attack on Hanggai, The Khagan of Monkhu Arku seized an all-out hunt on the yaoguai, including the remaining pieces of Rou Shan, who were continuing their rampage among the desert plains. While being pursued by the Monkhu Horde, they were redirected to the kingdom of Shaojhin in the east and managed to consume half of the country. However, as they reached a river that stretched across the entire country, they were left thwarted by the scolding hot waters of the river, which was being boiled by the flames of the sword of Dragon Emperor Ren, who was accompanied by Admirals Ox Lao and Snake Fu Bai, the seven hundred spears and shields of the White Horns, and the fifteen imperial legions of the Shilon Kingdoms. All who had come to avenge the death of Horse Emperor Malong.
The legions of Shilon pushed the army of yaoguai back into the south, but as they strayed further into their kingdom and closer to the enemy territory in Yamamura they were left at a stalemate. But with the Monkhu horde suppressing the yaoguai from the west, and the Shogun's naval forces trapping them from the southern and eastern shores, this horrific sea of monsters was surrounded. Through great might and sacrifice, the brave warriors of Kudao cornered them into their pit and were sealed beneath a mythical tomb created by Admiral Snake Fu Bai, who had buried himself to ensure the door between the living and the dead was never turned again.

The Kindao Army
Even in defeat, the Kindao’s invasion scarred Kudao for life, and for the worst. The Kindao army is an endless horde of Yokai that devour anything from soil to innocent souls. Those who fought a yokai soldier from the Kindao army close enough to be able describe it's facial features, and lived, have either been lost in pure dementia or paralyzed with fear by the horrors they saw in front of them.
Those who have been able to describe them illustrate them as living manifestations of ferocious monstrosity and darkness. Kaiju taller than palaces, trampled Tekkan with colossal power, giant flying heads that would grab you with its long black hair and devour you, animated corpses that ripped impaled arrows out of their spines to fire at you. And worse of all, some of these yokai were left behind when the gateway closed, and still lurk in the shadows today.
