Somehow this escaped me when I did the quick session recap on Sunday. The party got the drop on a bunch of bandits in Rappan Athuk - they got both surprise AND won initiative. This resulted in the bandit leader, the ogre and 2 or 3 others dead before the bandits could even respond. Moral roll was failed and they threw down their weapons after the party's thief called for their surrender.
The survivors, both human and orcs, asked to be spared and promised to flee the dungeon. The party asked them to map the part of the dungeon they knew, which they did (pretty much a beeline to the dungeon entrance). In return, the bandits asked if they could retain their daggers. I was surprised (and I'm sure the bandits were too) when the party agreed and let them leave.
I'm fairly stunned.
Of course, you know this will have to become a seed for something else down the line. This will have an impact on events in the area. No matter how it plays out (and boy, I've got some ideas) the players will know they had a hand in it ;)
