Play along the famous city 17 like a "witness" of whats going on. Just remember: You are not a heroe, you are [nothing].
Corpses will produce you psychological pain if you touch it or walk to near. The explanation is quite simple: No one would touch a rotten body in a wet dark place or in the middle of a battlefield. The pain wont be much, but in a long period of time it would kill you.
Only bloody or rotten corpses will produce this effect.
PD: Sorry for the lack of the logotipe, the artist's pc fried yesterday :l
