Meiko: Today I'm meeting with Jasper, one of the Knights of Matrech. Jasper, maybe you could start by explaining exactly what the Knights of Matrech are, and how they fit into the Matrech Guard.
Jasper: Both of them originated in the Zelmony Kingdom. Matrech was the capital of the kingdom, and so the Matrech Guard were the main force, setting them apart from vassal armies. The name remained after the kingdom split up, and is now still in use for the Matrech army. Within the original Matrech Guard, the Knights of Matrech were the elite troops consisting of high nobility. Their main function was to protect the capital and the royal family.
Meiko: But nowadays it's slightly different, isn't it?
Jasper: Yes. Despite the name, the Knights of Matrech are now separate from the Matrech army. Together with the Captain of the Matrech Guard, they form the backbone of the State Army, and it's their task to coordinate actions between all states.
Meiko: So the Matrech Guard is simply Matrech's own army, but the Knights of Matrech serve the State Union as a whole.
Jasper: Exactly. Local commanders will never be put in charge of divisions from other states, but the Knights of Matrech may be.
Meiko: I see. What's your current function within the Knights, then?
Jasper: I'm still a low-ranking officer. At the moment, I serve as one of the captain's personal guards. Normally, I protect her when she's on a mission, but I may also be dispatched in her place to deal with minor affairs, like with the liberation of Grunthall.
