The Chancellor? Nyx remembered the Chancellor from the party before the treaty signing but they hadn't shared words. Nyx hadn't really registered him as much of a threat at the time. He was clearly further out of the loop than originally thought. It hadn't been his his place to know though.

"I.. missed quite a bit." Was the best he could come up with at the moment. "I only know as much as the King told me, in the last moments of his life and none of it was in regards to the Chancellor being immortal."

Noctis he knew was the key to turning the tide but that was the extent of it.
