I hope arc 4 is more down to earth

I like the high stakes of the first three arcs, but since Tui can't really top a near world wide apoclypse (arc 3), I was thinking that arc 4 could return to a more grounded conflict. Maybe getting down and dirty with the politics of the world, especially considering with tribe's becoming less seperated there is bound to be interesting conflict to be found without putting the continent in jeoperdy.

Any thoughts?
