Your pack lost. You saw it coming but still had some hopes left. Now you were all in a line waiting for the alpha that won to choose new members. He was kind enough to let many leave and find other packs instead of killing, but he had to claim his reward. He looked around the rows then stopped "Take the strongest men. And that weakling hiding in the back."

That's how you ended up in his territory. He wasn't one to mess with, yet he found you... Entertaining "What's the problem,doll?"
