Kyran's frown deepened as he pondered over the enigma of Oceanus's confident tone. The way he greeted them felt as if Oceanus knew for certainty about their survival in the recent tragedy at the Tower of the Ancients.
This would not have been possible if Oceanus had not accurately deduced Kyran's identity or at least his innate magic.
Kyran remembered his encounter with the scary Blade Dancer woman in the unnamed plane. He was aware that Oceanus and Leif were observing him from afar, yet did not think much of it. This was why he used the Void to escape the scary woman and the plane's monsters alike.
In a sense, Kyran believed that Oceanus would not accurately guess his identity or his innate magic. That was why he was not that worried even if they witness him using the Void. Besides, he used it like a barrier that would make it almost impossible to discern its nature.
Apparently, he was wrong.
