Dialogue
HansExcellent timing! You must have caught the whiff
of easy money on the air, eh, my good
HansVery well. You seem trustworthy, so we shall forgo
the signing of any legally binding contracts.
But you must bring me 3 Aquamarines within
a reasonable time period! One more thing...
You need to be at least an Apprentice Miner to
successfully mine Aquamarines.
Don't embarrass yourself by trying if you're not
yet of a sufficient rank! Just buy them instead.
HansI strongly urge you to reconsider. The offer I made
you was quite generous!
HansWhat is this? You've brought me 3 Aquamarines!
Allow me to take those off your hands...
[Choice: Hand over / Keep for now]
HansExcellent! Now that I have the goods, you may
have your payment.
HansAre you thinking of selling the gemstones
to someone else?
Foolishness! No one in Reveria will offer you
a better price.
HansThe gemstones appear to be of a good quality.
I may require your services again in future.
