In the quest "Standing it Down" the following text appears.

Experienced Adventurer:
Determined not to return empty-handed, we crept into the bandits' stronghold and set about locating the stolen goods. Long story short, alarums were raised, rogues were awoken, and we fled in a blind panic. I was separated from my employer in the confusion and I've not seen him since.


I believe I have emphasised the pertinent part.
