not really explain as they moved on from it so far, but spoilers and popular conclusion said its due to jealousy and fear, of the barbarian country to the argan (kinda like how in Capri and Smyrna, invaded for no apparent reason other the fear of their potential) and that the barbarian prince wanted to kill her to finally finish of the royal family (to avoid rebellion, risk etc) the duke and his emperor were merely messengers as their kingdom have alliance to the barbarian country, so they are obliged to surrender the princess to the barbarian prince (which is the duke is reluctant to do)
alright that makes sense. a good story would explain that at the beginning though. thank you for the information! ヾ(❀╹◡╹)ﾉ~ where do you get your spoilers from if I may ask?
i read it in novel updates forum. some are in reddit. ╮(￣▽￣)╭
Apparently they were defeated b/c somebody from Argan leaked information to Ugel
Did I miss something or was there no mention of why the Argan empire was invaded and why the victors needed the princess to die until ch 17 at least? If it wasn't because they hated magicians and needed to make an example of her it would make more sense to marry the princess of the fallen empire off, which is what is usually done in stories like these. Seems like bad storytelling to me if that information wasn't lost in translation.
