This is Sapphire. I'm going to be brief about this, as I've got personal issues to cope with together with the fact that Sangria isn't among us anymore.
Since I've gotten enough watching the Mandalorians die, I'd not really want to see the Reavers following the same fate. Fortunately, and even if Silver may not agree, you are the fellow that could keep the company alive no matter your current status of recruit. Hell, who could say there's no competent color at the moment to take the lead? Suppose it'll be your time, sooner or later.
So aye, if you are really up to get the Reavers back on track fully, you would find this list of contacts quite useful, or so I hope. Former Mandalorian pilots mostly, probably most of them dead or imprisoned too, but maybe you could get in touch with this one Simon Templar, at the bottom of the list, Consul last I recall.
