Wait soooooo someone spooil me but could it be possible that his fated person changes to E...

I don't know the future, so not necessarily a spoiler, but my guess is that ennid manages to find a cure for MLs poison. That makes more sense based on the plot dyanmics

Take this w a grain of salt but I read somewhere that ennid is his mate and that's why they will choose not to have kids bc once a heir is born the previous dragon dies

But if they don't produce an heir he will die as well

But they did adopt a relative , can he still be saved or not? Also how come ennid's his mate, I thought the one he's destined with lives in the mountains

Didn't Ennid live in a mountain before they traveled? Or am I tripping?

Yeah, but the fated dude lives in a different country. Plus the fortune teller clearly stated that Ennid is not Glun’s fated partner. He did say that Ennid and Glun were destined to get married though. Just married. They can’t have kids cause someone else is Glun’s fated partner.
