Lares wants you to tell 
Caine, the Brotherhood's man in the Swamp Camp, to keep the strong herb rolls out of the New Camp. 
Baal Parvez can guide you there.
- 1Speak with Lares after joining the New Camp. He's worried about the potency of the Brotherhood's smoke rolls and sends you to deliver his message to Caine.
- 2Have Baal Parvez guide you to the Swamp Camp so the road is handled for you.
- 3At the Swamp Camp, ask
Cor Kalom where Caine is. You'll learn Caine has gone missing, which opens The Lost Apprentice quest. - 4Make yourself useful to the Brotherhood and finish The Lost Apprentice to track Caine down.
- 5Return to Lares and report what you found out about Caine to close out his part of the plan.
