First of all, I haven't played the Adventure mode that much, so I'm not quite sure what kind of features it has already. Anyways, here's the story:
---somewhat irrelevant story begins---
My best character yet got a quest from a human town mayor to kill an elite kobold bowman. I departed the town and was very desperate to have recieved a suicide mission. I sneaked around in the cave, stabbing kobolds in the heart with my well made iron spear. I walked on a stairway, and suddenly got the "I am blah blah blah" message. The odds were in my favour; the kobold elite bowman was standing right next to me, and it was my turn. The first (and likely to have been my only) attack solved the battle right away. I stabbed him in the heart, and both lungs, effectively rendering him incapacitated. So now I stab him like a maniac until he's dead. I grab his good loot and head back to the town.
---somewhat irrelevant story ends---
So I arrive to the town at night, so I go into the tavern to wait to talk to the mayor, and sleep on a bed. But when I wake up.... almost all the people in the town are dead, including the mayor. Some of them were killed in their beds, some corpses are scattered outside. There's lots of clothing and pieces of armor around, too... I'm sure this wasn't one of the towns I had raided with earlier characters, and I'm also sure the corpses weren't there the first time I visited the town. Can't be 100% sure about the night because... it was dark :p .
So I'm wondering... What on earth happened? :O
