Bearclaw Valley [intruder] pack, pack, kill, kill

This was more of a struggle than Evien had anticipated Astara having with the intruder. He had to get involved - he didn't want to, but... well, sometimes it was necessary. This was brutal and bloody and dangerous, and he couldn't let a packmate just get hurt like that. 

The medic lunged forward, aiming his jaws at the stranger's neck. He intended to go for the scruff, but at the angle, it was impossible. Teeth sank deep into fur and flesh, and Evien yanked her backward in an attempt to get her away from his co-lead. Blood flooded his mouth - more than he thought he had drawn from the she-wolf - and he nearly choked on it. 

But he was not without injury, either. Sharp pain bloomed on the left side of his face, right over his eye, and he belatedly realized that the world had gone dark on that side of him. Teeth would clench harder at the pain, a deep growl rattling in his chest. He didn't know what had become of his left eye - whether it was still there or not - but at the moment, it didn't really matter.
