Hideaway Strath Whims of Fate or was that strings?

The fact that this was a spar and not a true fight was one of the two reasons Nyra didn't simply kill Whrist and get it over with. 
The other reason? She didn't want Donovan to kick her ass again for injuring and nearly killing a packmate.

Keeping her unrelenting grip on Whrist's windpipe, she continued to hold her there. Nyra certainly had the power to do so, especially where she was continuing to tighten her group while making sure the rest of her mass was held firm, blocking Whrist from getting her feet between them both.

Truthfully, Nyra wanted Whrist to give it her all. She wasn't a dedicated fan of easy wins, so an opponent as determined and fiery as Nyra herself was, is definitely a treat. Friend or not, they could learn from each other.
