Would be nice to have a Nomadic Outcast Group that actually try to cure themselfs. We ain't speaking about the WHOLE OC as in a bunch. A mix of Kusari Exile and Phoenix probably <- Maybe a bad example but as close as we can get to explain.
But all in all. Why not? Why wouldn't some of them risk that and live Nomadic, while Corsairs would lend them Hospitality and respect their Honor in risking this just for the Cure.
Hell I would even think that Sairs would Honor such ally, which almost risks so many things just for that.
