Rebuilding Squid Coast

I like the idea of being able to expand the campsite and populate it with the villagers you rescue. It would add a nice feel of progression to the game, when you're playing the missions more and more. Furthermore it's a new place to spend emeralds. Like you could use your money to repair peoples homes, rebuild the shops and farms, and fortify Squid Coast against further attacks. 

In addition there would be further attacks, and a few missions where you could further help squid coast. I don't know what those would be, but this is a start of an idea that I think could be expanded upon.
