Escort Professor Phizzlethorpe to the cave and back.
Now that we are full-fledged Blackwater Raiders it is our job to help Mr. O'Breen locate the lost elven treasure.
It is next to impossible to find the gems in the dark sea without aid. The doctor has constructed some goggles that will help. He needs the goggles charged with the energy derived from the enchanted stone in the cave just up the hill.
But the cave is cursed! When we get close, we get ambushed. Defend me and I can harness the energy from the stone into the goggles.
The goggles work perfectly now! Well done, <name>.
