Kingdom of Raja

The Kingdom of Raja (ラージャ小亜国) is a small nation ruled by Queen Towa, located west of the Jura Tempest Federation. It is the main setting of the movie Scarlet Bond in which it was infiltrated by Daemons. The nation is located on a strip of land surrounded by towering cliffs and numerous waterfalls that feed the lake below neighboring the kingdom. It was founded by a gathering of those that escaped from oppression, providing refuge to Humans, Demi-Humans, and Monsters.

Background
During its earliest days, Raja was the target of numerous threats. It was constantly met with pressure from attacks by the ferocious Monsters of the Jura Forest, as well as greedy human nations that desired cheap labor. As it was not a great nation similar to the likes of Dwargon, the pressure was more than it could handle. The queen at the time despaired at her people's predicament and desperately prayed for a breakthrough. Eventually, her prayers were answered by the figure Violet and she was granted a special tiara that could give her the power to save her people.

The queen used the tiara to enrich her nation, but as a consequence, she soon passed away to the risks presented by overusing the tiara. Despite the nation acquiring newfound wealth, it did not get any easier for the following queens to deal with the attacks aimed at them. In fact, the discovery of the gold mine dormant beneath the land caused the attacks to intensify, but through the power of the tiara, the nation nonetheless endured.

Change would later come when Lacua, a Daemon serving Violet, sought to curry favor with her by poisoning the nearby lake. Since the poison was reinforced each time it was purified, various generations of queens were forced to rely on the tiara more than ever to cope with this disaster. This plight serves as the key premise of Scarlet Bond.

Government
Raja is a traditional monarchy. Below Towa is the prime minister, and being the small nation that is, there is only only one minister under him. Towa's approach to governing is an active, hands-on one that allows her to promptly respond to her people's concerns.

Military
Raja's military is 2000 strong. The nation has shown to domesticate their own flock of Wyverns hinting at its potential for aerial combat. Hiiro is the strongest combatant within its ranks.

Economy
It does not have any local specialty nor is its food productivity very high. The local gold mine was its main source of income for hundreds of years up until it dried up. It currently relies on the resources of the Jura Forest to sustain itself. It is also a trade partner of Tempest, selling to them their newly discovered iron ore.

Trivia

 * Despite being introduced in an anime original work, it is canon to the Light Novel by virtue of being referenced in the spin-off How to Spend a Certain Vacation which is directly written by Fuse and confirmed canon to the LN.
