Guard Jacob:
How do you do, honored traveler? Have you come to our village to see the great shell of cruma? If you have, then you'd be well advised to give up your search. Many have come to this village to view the shell of cruma, but I have rarely seen anyone return from that place intact. The Marshlands where the shell of cruma lies have for ages been a place teeming with monsters -- even our guards don't like to go near there.
Ask about cruma
Ask about the Marshlands
Ask about the local lord and tax rate.
