Upon getting closer, Niks started to hear the, in his assumption, almost finished battle nearby, if the battlecry was an indication. Although there was something about the voice that seemed to bother him. As he can start to discern the two fighters, his tail started to flick in agitation and he frowned. He couldn't believe his eyes, even with the whole dimensional travelling of the gates, the sort of thing he was seeing at the moment should not be possible! 

Niks stopped in his tracks over the sheer weirdness of the sight. He stopped as he saw an elf made a stabbing motion at her. He stopped as the gesture connected but failed to prevent the horizontal movement the girl made. He stopped and didn't do anything but stare. Even if he tried anything, only him shouting would had a chance of disrupting the fight, he was too far for anything else.
