* Kian or Cain is indeed a royal, but an illegitimate one. His mom was a saintess & she was the one who put a curse on him (I don't remember why lmao)

* Marchioness Justaccia will be the empress in the future

* Motia will be an independent territory, a pretty powerful one too because of the archmage & the sword master couple

* Harriod (blondie prince of the West) will find his match & fall in love. His son will fall in love with Kian & Countess' daughter.

* The main couple will age pretty slowly because of their powers, something their children inherited.

If you're up for it, there are more detailed spoilers in novel updates forum. Just google the title of the manhwa & add spoilers at the last part, & the first result should be the correct site.
