This is not a spoiler cause it doesn’t happen in the manhwa but...beware.
Frion Knights were not robots in the story. They were Gollems, magical avatars that were made to do their creator’s bidding.
And what were they made of: Girls with Magical Powers.
And how did they get the Girls: Frion Knights would wipe out Villages in the dead of night. Kill everyone and steal girls that had been shown to possess magical powers. That’s why they were no girls with Magical powers. They were killed and their parts made for Frion Knights. And I do mean parts. They never explained how they used the parts though.
And Freesa: Freesa was locked up in a Dungeon of the palace and made to give birth to girls multiple times ( magical pregnancies) so the Emperor could chop them up and make Frion Knights and steal the Saint.
The only thing That never got explained was, what did the Emperor want the Saint for. It made no sense.
The novel was way darker. You guys don’t even want to know what they actually did to Princess Freesia.
