Hades was wary of Varian. But not to the point of paranoia.
So, while he correctly identified Varian as the biggest threat to his rule, he did not think the 'boy' of a few thousand years would be capable of any ridiculous feats.
All of Varian's specialties were attributed solely to the slivers he held, not the man himself.
This was the common opinion of all divine rankers across Eden, be it the Jai or the alliance.
But the slivers themselves had a different opinion. He didn't become special because they chose him. When there were so many people, why did they have to pick this one delusional, depressed young man?
No. They picked him because he was special.
Logos was clear that anyone else who tried to wield the slivers would've been subject to intense upheavals. The question wasn't if they'd die, but when.
Varian not only survived such twisted fate, but he thrived.
Unfortunately, Hades did not know.
"Here it comes."
Varian raised his hand.
