Tracking down Caine in Gothic Remake took me longer than I'd like to admit. This missing mole is apparently somewhere in the Swamp Camp, but if you're ever been to that sprawling mess of ramshackle huts and walkways, you'll understand the issue. If you recall that Caine is Cor Kalom's apprentice, then speaking to him will give you some guidance.
Even then, though, you still have to track down his hut based on a very vague description. I'll run you through The Lost Apprentice quest below, and explain the long process of tracking down Caine.
