which chapter
The manhwa is not following the novel but what chapter are you talking about with the portal? you might be talking about Aeternitas (is that how you spell his name?) if the "prince" had shoulder and messy hair
It was about Claude's past, when he was searching for his brother & that one was looking with an absent in front on a portal
Oh ok. So the one that Anastasius was โlookingโ at was Aeternitas, the one who Lucas calls a weakling but turns out to be the strongest emperor. So when they were kids, it was shown that Claude and his brother had a good relationship, until Anastasius was possessed (I think)
I need EXPLAINATION
Even tho I'm not sure if the manhwa follow the novel anymore, I've never read the novel,, who is that prince with black hair that he saw & the figure behind the portal before
