Well I see the only character left is Papa sharptooth for needed FCs. I'm not sure how I'll do with him but I can give it a shot to fill the gap.
Also, for OC's I'll bring in Twiz and his mom, who we'll name Arkera. Their herd too, but those will be the only defined ones for fitting into Redclaw's gang I'm thinking. They can be sort of looks outs or scouts.
