Immortality

"Aion, I remember you saying you won't talk to me until I stop my prophecies. What made my stubborn brother give up his own word?" 

In a chamber of the city lord palace, Eon sat behind a desk built purely of glowing golden aura and smiled at the older-looking man.

"Elder brother." Aion addressed him with respect. 

Outside, he addressed Eon by his name and the latter didn't refute it to protect Aion's image. But in private, Aion showed a lot of respect to his older sibling.

It's comical for a man who looked to be in his 70s to address a man barely into 30s as an elder. But once anyone knew their divine ranks, it'd be obvious. A peak rank 2 had far longer lifespan than mid rank 2s.

In fact, Eon's proper appearance was supposed to be that of a child six years. He had aged more than he should've—at least by five more times in fact.
