Okay guys this is just a thought. But obviously it is aeternitas in the older brothers body. And since he knows of divine beasts. What if he met lucas when all his magic was in his divine beast, making lucas think that he's weak. But after he absorbs his divine beast, he becomes the so called strongest emperor in history (though hopefully not as strong as lucas). Maybe he holdes a grudge against lucas or something and wants to become emperor again possibly after finding some way to possess anastacius.

okay this is from the novel. The brother of claude is the first prince now. The soul of the first prince is in his body bcs the first prince uses black magic. He learned black magic to get lucas attention. He wanted lucas to be his teacher bcs hes a big fan of lucas but lucas rejected him right away. It still didnt stop him from getting his attention and mastered black magic to get his attention but lucas didnt care until when lucas came back from sleeping (remember how lucas said that hes been asleep for thousands of years) the first prince used the brother of claude's body to try to get his attention in this lifetime. He did successfully and thats the reason hes going all this lengths just get his attention. Thats why hes also mad at athy for being w lucas a lot.
Claude going off to sleep st the drop of a hat is like the most frustrating thing ever. Please progress quickly dear story.
