Convergence

Rowan Empyrean Sight became the method he observed the world when he lost his Soul and for a lot of the time, he disregarded a majority of the information he had access to, either because they were meaningless or he did not understand it.

Rowan did not need to know the taste of the blood of an insect that was a thousand miles away, or that a certain mortal heartbeat was too fast, or the scent of light and so much useless information that his Empyrean sights had access to at all time.

Perhaps if he had dwelled in a mortal world for a long time, then such sensations and observation might have been important, but Rowan never walked those paths, his own had been a narrow one, and as a price for power he did not regret not living as a mortal for an extended period of time.
