No, actually, they are knights. Their starting class is knight for all of them. And even if some group of "hunters and adventurers" calls themselves knights of a normal state (and Erathia is a normal state), then that state should either subject them to trials and, depending on the results, either knight them or disgracefully banish them.

Or maybe they were kicked out of Erathia and decided to try their luck in Jadame:D :D

And besides, they came to hunt, not to wage war against their own kind.

P.S. I'm defending them not because I agree with them, but because no one else is, and they are a prototype of us. Don't people also treat each other like that?
