Siren
For the first time in a long time, Nero completely lost his composure. As the illusory image of Virtuous Moonlight became solid, and the sense of being observed by a superior being faded, Nero became aware of the fact that something historic had just happened to him.
He had felt the aura of Sages before, but even they could not be as overwhelmingly as what he had felt. Sages, no matter how unbelievably powerful they were, still felt like they were human. They were just very strong humans, standing at the peak of their species. But whatever had looked down on him… if Nero believed in religion, he might have thought that a deity had looked down on him. Since he didn't, the most logical answer his brain could come up with was that a very, incredibly powerful Eldrim had peered over at Nero.
