Like in the real world, at some point, something happens which shakes the balance... someone wants more power or wants to become The Big Dog.
Example Atamara, there was quite attempt to reduce this central atamaran alliance power, but it failed. Not because Central Atamara was so strong, but because rest of us sucked and we didnt want it enough. South chickened... north fumbled cause of mixed diplomacy.
But i have no doubts some day, someone will make the CE/Tara block to collapse. There are boring times, then people leave to other islands, that opens up oppurtunities to new players get in power or influence current people at power.
