Interesting choice, there, Blackthorn but it does make sense, I suppose.
Given the Kazari's strength, he'd likely have an easier time carrying Kith back toward the camp and it would give the party a fighter-type at the "rear" on the off chance that we'vve got rotters coming at us from that direction. Soooo, Ch'dau will comply with Khan Aranwen's orders (albeit perhaps not "happily" as he's still hoping for some blood).
I'll try and get a post put together in that regard but, if Olan is looking to get something tacked up before I can do so, just wanted to acknowledge that, yes, the Silver Cat will take over the returning of Kith to camp.
