Marriage is a sacred ritual where a man and woman form a bond as husband and wife.
While this has been the custom of human society since the ancient imperial era, things were somewhat different for nobles.
Unlike common humans, as descendants of gods, they needed to spread their magical bloodline as much as possible.
Noble marriages came in two main forms.
The first was companion marriage, similar to commoners' marriages, between magical users of relatively equal standing.
The second was subordinate marriage, where multiple inferior magic users were bound to a superior one.
What the seven houses proposed was the latter - they would offer women born with some potential, daughters of knights, as concubines to Turan.
Naturally, as mere concubines, they wouldn't dare interfere with Kalamaf's governance.
"Of course, they're young ladies well-educated to become concubines of noble ones, lacking neither in appearance nor refinement."
