Honestly we I believe we should wait, because holy crap we weren't even close to finished discussing everything.

At any rate, the other two locations are important to. And let's not stop with just figuring out what resistance lies there, but what main threats and facilities they have to deal with as well. IIRC, Eggman built a factory somewhere near Green Hill. Exhausting the land of its resources and minerals, the area around the factory is turning into a desert.

At the Mystic Ruin, we have Final Egg, which has expanded large enough to overtake half the jungle. This is where Eggman's fleet of airships come from; as such, shutting it down is vital to the heroes' victory.

As for the other two locations, I'm thinking somewhere overseas from the mainlands and South Island. I'm thinking that this is one place where the resistance split: After a crushing defeat some were forced to flee in another direction to the east, and began regrouping at a new location. The rest who made it back to the original base were immediately ambushed by the enemy, leading them to abandon the base entirely. The few survivors headed south. The failed mission was to prevent the launch of the Death Egg. No doubt this is where Tails and Knuckles fell next.
