The nation of Tianoku was founded when the seven cities of the east were united under the great hero Lu Jin shortly after the World Cataclysm. The legend is that Lu Jin only ruled his nation briefly, before taking a fateful journey into the mountains and never returning. Despite this legend, the Lu Dynasty continues to rule Tianoku today.
Tianoku is a coastal nation, with the Endless Ocean bordering it on it's entire left side. To the north are the Goblyn Lands, which despite continual invasion, have been kept out by the city of Kuni. West of Tianoku is the city-state of Wastryana, and further south is the forest of Folalia, as well as several city states, including Sindweth, Kyth-Tiras, Gataania, and Tazarya. Tianoku maintains good relationship with the southern cities.
The most prominent religion of Tianoku is Dyaus-Oter, who is regarded as the god of the four winds and the guardian of the nation's ancestors. The two warrior gods Shiro the Justice Maker and Kuro the Lawgiver are also widely worshipped, though the followers of one god seek to eliminate the other at every oppurtunity. Outside of this, worship of ancestors, dragons, and elemental spirits is very common among the people.
The arcane arts are viewed in Tianoku with much suspicion. At best, users of the arcane are often hermits, who keep themselves in seculsion. There is a wide reputation for many arcane spellcasters to consort with demons, and taint their blood with evil powers. As a result, spellcasters are often distrusted or regarded in high suspicion.
Elves are more common to the south, while Dwarves are generally more common in the mountainous regions. Tianoku is also home to the infamous Brown (gully) dwarves. Goblinoids also are prominent to the north, though are reviled as an enemy of the nation and destroyed whenever they come too close. Monstrous populations are rather high in Tianoku as well, with giants being a large portion of the threat.
The city of Kuni is in charge of maintaining the outer defense, and are generally regarded as brutish warriors and barbarians. Despite this, they have thus far been successful in keeping the goblins from overrunning the nation, and thus are agreed to be nescessary, even if they are not viewed highly by other cities.
Sasori is a large city, known for being a dangerous place to frequent. While there are a lot of luxurious parts of this city for nobles and folks with wealth, generally it is known that most contacts with the underworld, including the Thieves' and Assassins' Guilds occur here.
In the opposite vein of Sasori, Shishi is known for being a very orderly and well taken care of city. Albiet, a good deal smaller than Sasori, Shishi is known for giving rise to powerful orders of samurai. The church of Shiro is most prominent here.
The emperor resides in the capitol city of Riva-Tsuru. This is also the largest city of Tianoku, only being challenged by Sasori in terms of population. Most of the population of Riva-Tsuru are regarded as well cultured, and generally maintain the strong traditions of Tianoku.
To the south, the holy city of Fen Xu is the location of the largest temples to Dyaus-Oter. Additionally, the shrines of the elemental princes are located here, and it is widely known that most priests of the elemental tradition begin their learning here.
Within the mountains are the two smallest villages. The first is that of Ryuji, known to be a mysterious place where monks often travel to study philosophy and gain wisdom. The second is Ikkakuju, which is known for being a barbarian outlander tribe, barely within the jurisdiction of Tianoku. they are widely considered outsiders, and generally avoid the rest of the nation.
It should be noted that the Ikkakuju were much larger before the hordes of Verdorbanon charged through the nation's western border and destroyed most of them.
