You reported the success of your duty at Ordlac's house and delivered the dagger you found to Dudsig.
'This poison upon the blade of this dagger is secreted by the slugs that dwell in the marshes to the east. It is quite deadly and must be collected with much care. Perhaps that is where the leader of these brigands skulks?
'If so, he should be dealt with...perhaps if you are able to dispatch him, his followers will return to the Stonedeans and leave us in peace.'
The brigand leader may be found in the marshes east of Oserley.
Dudsig has asked you to find and defeat the leader of the brigands who assaulted Lúfa.
Dudsig is near the stables in Oserley, west of the marshes.
You should return to Dudsig with news of your success.
