ISO Navira's Sister

This is pretty much exactly the line of thinking that I wanted for this relationship. I would love to see these two but heads over clan-wide decisions - Navira would definitely want to take the "brains over brawn" route. Like you said, they love one another but each would have very different ideas about how to lead the pack. It would be really interesting in this regard for Navira to consider her sister as her general when the time comes but ultimately decide not to. I could TOTALLY see that causing a rift.

I do love the idea of the "big sister, baby sister" play. I can see Navira getting picked on for being the "baby" and therefore inferior or incapable of making decisions as well as Areli.

I think that a part of Navira is really hesitant to take the job of leader, so it might be fun to see Areli, in the midst of the position being open, trying to make some decisions for the clan as well that Navira ultimately disagrees with? Things that make her step up and go "Okay, I feel like I need to be the one to take charge here." A bit of push and pull before Navira is cemented in the role. I think it's only natural for multiple dogs to go toe-to-toe for leadership when the position is open, right?
