Swiftcurrent Creek origin stories

Gannet had assumed her fights were always dad's fights, and vice versa, but it was hard for him to imagine there being a time when the two of them weren't a match set.  He'd lived somewhere else?  Then how had they met?  He never saw wolves who lived other places; he thought that was kinda the point.  But he didn't ask, since it didn't really matter now and he already had a bit to think on from what had already been said.

He was fairly certain on one thing - he'd never try to take someone's pack from them.  Why would someone even join a pack if they didn't respect the leader?
