Lescatie, which boasts one of the largest sizes among the monster nations, under the leadership of the diplomat Castor and his wife, a Youko, is engaged in active diplomacy not only with other Mamono nations, but also with other existing human nations. While the old Lescatie was a large country, its industry was underdeveloped and diplomacy relied primarily on the power of Heroes. Lescatie provided other countries with "military power," sending Heroes and Knights to prevent monster invasions under Lescatie's auspices; maintain security by performing punitive operations against bandits; and occasionally provide its forces in wars between human countries. In return, Lescatie received products or money as "offerings to God," which maintained the country's financial strength. The nations protected by Lescatie were able to maintain a certain level of security. But weak countries and remote villages that suffered from famine without rich harvests and could not afford to pay Lescatie were unable to obtain such protection. Moreover, even after they found themselves placed under the protection of Lescatie, the Lescatian upper classes, allied with the aristocrats of their neighbors, simply robbed the common people to nothing, and some of the knights who were supposed to protect the people but had evil intentions in their hearts, often made them suffer.
At present, however, such payments to the government in exchange for military aid are not made. On the other hand, Lescatie still provides other countries with "military forces on credit," such as by sending Dark Knights to them in response to their request for assistance. In return, Lescatie asks for alliances between countries and help in the development of its lagging industries, such as transferring technology or sending engineers from other countries to Lescatie to exchange experiences. In addition, Lescatie has friendly diplomatic relations with many countries that have become mamono realms because of her expeditionary missions. Her diplomats have been particularly active in working with such countries during the unstable transition period, helping them manage to become a stable monster nation sooner. From other countries that have become abundant mamono realms, many different local products are now imported into Lescatie, such as Mamono Realm Jam and others. Often, in response to the dense magical atmosphere of Lescatie, such products themselves undergo changes and new goods are brought into the world and re-imported into other countries.
In Lescatie's diplomacy, a rare mamono realm ore called Druelite, which is mined only here, plays an important role. This red glowing ore has not only a beautiful appearance, but also the ability to amplify stored magical energy. It is used as the main source of energy that solves various problems. Regardless of what mana has been accumulated in it, human or even divine, the output will be enhanced mamono mana, which will have a completely black color. An land where there is a lot of this ore is bound to turn into a mamono realm. As I have been told, Druelite and the goods produced from it are delivered to the poor and barren human lands in various ways. In addition to the neighboring human and monster lands, Lescatie has now expanded the scope of her diplomacy to these small countries, to which she previously paid no attention when she was a pro-Order religious state. Also, in recent years, in order to attract the "human men," who are the most important factor for the Mamono country, an alliance with Dragonia, one of the largest tourist countries, has been initiated by Lady Wilmarina in order to turn some of Lescatie's cities into tourist areas.
