Sylas composed himself for a moment before he began to speak. But rather than words coming from his mouth, the echoes of Ancient Ithkuil latched onto the Aether in the atmosphere and began to form one Rune after another.
The change was shocking even to Sylas, so much so that he suddenly stopped. It was only when he saw that Nosphaleen was in a daze that he realized he might have ruined that, and he quickly continued.
Because of Insight, Sylas' comprehension of the Mesmeryx Serpentes Race was extraordinarily deep, so much so that he was easily the equivalent of a professor who had completed several graduate degrees in the field.
All of that knowledge, though, was locked away deep within him and there was no easy way to share it with Nosphaleen.
If he just spoke of it normally, he didn't believe that this sort of last-minute preparation would have any sort of helpfulness at all.
