@SanszNom that's not it at all.
In the fog puzzle you have to walk around and click on where you hear the sound most (of the poem words) wind, birds, sea and silence
PROTIP for the hard badge: You can AVOID FIGHTS!
On the 'prepare for battle...' screen you can avoid the battle by just right-clicking with your mouse and clicking 'back'. tadaa
And even better: The city is then captured!
A very cruel thing in the game is being poisoned...gives tons of damage and goes on FOREVER. I'm stuck in the game cause of this. I saved my game while i was poisoned and cant even reach a shop for an antidote cause I always die after a few steps! dude!
