A surprise attack paved a path for both Nix and Waltner akin. And this is something that's bound and prewritten by destiny. The one who wins will change the tide of war. An easy, sure-fire kill for both sides.
As though Waltner had already seen the ending a smile bloomed on his face. A smile of relief, a smile that contained sorrow one wouldn't able to predict what was really in his mind unless he utters his feelings but, for some reason, Nix sensed sorrow in the edge of the blade that was approaching him while Nix's had nothingness.
Nix's mind was blank at that point. His sword didn't carry a purpose or passion. IT was an empty blade that didn't carry any emotion. Unlike most people's expectations, none died as their swords collided.
The huge repulsive wave transferred a shiver down the spines of the spectators. Surmise one was to fight these two deadly men they'd surely die akin to any other human regardless of their race.
Sorry if you felt like this is a filler but, Waltner's perception about Nix had to be revealed and why he fought with him to death.
