Lind had vast experience with thralls at the current moment but the current one was odd. He felt the familiar connection to a Fiend in the young man when he checked him for injury but what made that odd was he should have felt it on sight.
As he examined the man, he noticed he was totally blind to Celestial Qi he was using to manipulate the wards and Laws around them. It had started as a simple experiment but while everyone else knew what he was doing, the man clearly did not.
Why would a thrall be blind to Fiend and Celestial Qi?
He began to isolate the connection but unlike before, there was almost no resistance. It was like the connection was a thrall one but intentionally sectioned off.
He recalled his difficulty in using Celestial Qi below a certain purity and wondered if Fiends had the same issue. It would partially explain why they had vanished from the world so far as anyone could tell him.
