You could be opening Pandora's box. Just look what happened between KWG and Cliffs.

No new company needs to be established. If cooperation is needed between companies of the Ring then a memorandum of understanding signed by participants may be enough.

As for Matawa, absolutely not. All of them are not entitled. I can see some compensation paid to Webequie because they are the nearest community to the Ring and may have some legal reason to be compensated. But not the others. If you renumerate them all then you are rewarding all the bad pr and troubles that they gave us.

Webequie, Marten Falls and a few others get road, communications, electrical power, perhaps even railway usage, not to mention jobs and lower costs for just about everything as exchange for abandoning old ways and joining modern society. They need more?
Through rewarding you are encouraging a dual class society.
