The Kingdom of Mithra, northern border, Duke Streim's Territory.
In the past, this had been one of the Kingdom of Mithra's foremost territories and powers.
There was no other reason for it; it was simply because the one who ruled here was a duke, a relative of the Mitra Royal Family by blood.
Moreover, Duke Streim's Territory held a status within the Kingdom of Mithra that no ordinary ducal house could compare to.
It bordered the Ragna Empire's territory. Whenever the Ragna Empire and the Kingdom of Mithra stood opposed, should the Kingdom of Mithra be invaded, this would be the first place trampled by the Ragna Empire's iron cavalry.
It had clashed with the Ragna Empire's armies and the Empire Knights several times, igniting many small-scale wars, and had ultimately succeeded in repelling the Ragna Empire's forces every time.
It could be said that Duke Streim's Territory was the first line of defense protecting the kingdom from the Ragna Empire.
The kingdom's lands had not suffered an invasion from the Ragna Empire for the past thousand years, and Duke Streim's Territory's contribution to that was undeniable.
Naturally, the Streim Family's standing in the kingdom had become extraordinarily prominent, to the point that even the King had to show its head three parts respect.
Unfortunately, the Streim Family's glory was no more.
The family head, an iron-blooded general, had vanished roughly half a year ago, his fate unknown.
The Streim Family's only son, the family's heir, had also disappeared during the Cosmos incident.
Even the First Knights of Duke Streim's Territory, its Knight Commander, and the commander-in-chief of the Knights, the territory's strongest individual, had all vanished together.
The disappearance of such an important group of people and vital combat power had utterly pushed the Streim Family into the abyss.
